Executive Summary
The purpose of this report is to provide information to several stakeholders and to satisfy the regulatory
requirements of the Safe Drinking Water Act (SDWA) including the Drinking Water Quality Management
Standard (DWQMS), and regulatory reporting required under O.Reg. 170/03 (Section 11 and Schedule
22). The report is a compilation of information that helps to demonstrate the ongoing provision of a
safe, consistent supply of high quality drinking water to customers located within the City of Guelph and
the Gazer Mooney Subdivision (located in the Township of Guelph/Eramosa).
Water Services is a municipally-owned and operated water utility established in 1879. The Guelph
Drinking Water System (Guelph DWS) is a Class IV Water Distribution and Supply Subsystem and is
composed of water supply and treatment facilities and a water distribution system. The Gazer Mooney
Subdivision Distribution System (Gazer Mooney SDS) is a Class I distribution system supplied with water
from the Guelph Drinking Water System.
Both the Guelph DWS and the Gazer Mooney SDS are required to comply with the Safe Drinking Water
Act (SDWA) and Regulations as well as requirements contained in Permits to Take Water (PTTW),
Municipal Drinking Water Licences (MDWL), and Drinking Water Works Permits (DWWP). Having met the
quality management system requirements of the SDWA, Guelph Water Services is an accredited
Operating Authority with an up-to-date Operational Plan (OP). The OP is available upon request from
Guelph Water Services.
The source of Guelph’s drinking water is a series of 21 operational groundwater wells and a shallow
groundwater collector system; this system consists primarily of true groundwater sources, with some
“groundwater under the direct influence of surface water with effective filtration” (GUDI-WEF) sources
(i.e. Carter Well field, Arkell 1 and the Glen Collectors).
The City has approximately 41,653 fully metered water service connections, 542 kilometres of
underground watermains, and a population of approximately 126,250 within the City of Guelph. The
Gazer Mooney Subdivision has approximately 70 fully metered water service connections, 2 kilometres
of underground watermains, and an approximate population of 200.
There were no incidents of non-compliance (described in Section A of this report) associated with the
Guelph DWS and Gazer Mooney SDS in 2014. As the Operating Authority for both systems, Guelph
Water Services is annually inspected by the Ontario Ministry of the Environment and Climate Change
(MOECC) for compliance with regulatory requirements. The results of the 2014 Ministry of the
Environment and Climate Change (MOECC) Annual Inspection Report for the Guelph DWS and Gazer
Mooney SDS are still pending.
From Jan. 1 to Dec. 31, 2014, Guelph Water Services reported three Adverse Water Quality Incidents
(AWQIs) in the Guelph Drinking Water System: one of the incidents involved the detection of Total
Coliform at a well site above regulatory limits; the next incident was related to sodium results above the
reporting threshold, but within the aesthetic objective; and the last incident was related to temporary
UV disinfection system failure. There was one AWQI in the Gazer Mooney Subdivision Distribution
System related to sodium results above the reporting threshold, but within the aesthetic objective. In
conjunction with Wellington-Dufferin-Guelph Public Health and the MOECC, all appropriate corrective
actions and reporting were completed.

Water Services’ risk assessment updates, emergency response testing, internal and external audits help
facilitate continual improvement of processes and systems through the implementation of corrective
actions.
The water system is operated to meet daily, seasonal, and other operational demands (fire demands)
with various combinations of supplies in operation at any given time. From Jan. 01 to Dec. 31, 2014, a
total of 16,594,145 cubic metres (16.6 billion litres) of water was treated and pumped to the system.
The average daily water demand was 45,463 cubic metres (45.5 million litres). The highest daily use of
water occurred on Jun. 17, when 52,614 cubic metres (52.6 million litres) of water was pumped. The
minimum day production of water was 32,644 cubic metres (32.6 million litres) and occurred on Dec.
26, 2014.
All water provided to the Guelph Drinking Water System and the Gazer Mooney Subdivision Distribution
System was treated with sodium hypochlorite (for chlorine disinfection) with some sources also using
ultraviolet disinfection (UV). All supplied water was tested and met all regulatory standards.
City Guelph Water Services maintained the drinking water system in a fit state of repair and followed
best industry practices during the repair and maintenance of the system.
Details of ongoing and emerging water quality, supply, and distribution initiatives are outlined in Section
J of this report and include successful programs related to: water conservation, source water protection,
and lead reduction. Water Services continues to implement recommendations of the Water Conservation
and Efficiency Strategy, awaits MOECC approval of its policies to manage significant drinking water
threats through the proposed Grand River Source Protection Plan, continues to invest in the Arkell
Springs Forest Stewardship Project (to protect the Arkell Wellfield’s source water quality), and is
successfully implementing its extensive Lead Reduction Plan in accordance with the regulatory relief
provisions of the SDWA. The Lead Reduction Plan is partially grant-funded, and from Jan. 1 to Dec. 31,
2014, there were 11 full or partial replacements of lead service water lines.
Water Services’ Operational Testing and Adaptive Management Plan continues to assess the aquifer in
the area of the Arkell Wellfield and pumping conditions to determine a sustainable capacity with respect
to environmental conditions in the area. Infrastructure review occurs regularly between Engineering and
Water Services to optimize priority projects and minimize common costs. Work related to the Water
Supply Master Plan update is ongoing.
The City maintained a robust backflow prevention program overseeing 2,652 properties with 6,149
backflow prevention devices installed. There were no reported backflow incidents.
The City has completed this Annual & Summary Report to satisfy the regulatory requirements of the
Safe Drinking Water Act, O.Reg 170/03 (Section 11 and Schedule 22). For more information please

Systems Overview
Guelph Drinking Water System
The mission of the City of Guelph’s Water Services department (“Water Services”) is to provide customers
and the community with a safe, consistent supply of high quality drinking water while meeting, exceeding,
and continually improving on legal, operational, and quality management system requirements.
Water Services provides and promotes reliable, cost-effective systems for the safe production and delivery
of consistently high quality water.
Water Services is a municipally-owned and operated water utility established in 1879. The Guelph
Drinking Water System is a Class IV Water Distribution and Supply Subsystem and is composed of water
supply and treatment facilities and a water distribution system. From Jan. 1 to Dec. 31, 2014, thirty-five
water operators and staff were certified to operate and maintain the water systems.
Water Services maintains full scope accreditation to the Drinking Water Quality Management Standard
after a successful on-site audit in June 2014 conducted by a third-party accreditation body. This full
accreditation satisfies part of the requirements under the Municipal Drinking Water Licensing Program.
The distribution system (including watermains, valves, fire hydrants, services, and meters) serves a
population of approximately 126,250 within the City of Guelph. All new system components meet NSF 611
requirements or approved equivalents and are installed and maintained in accordance with approved
industry standards. The system is fully metered.
The Guelph Drinking Water System distribution system is comprised of the following infrastructure:
- 6.38 kilometres of 900-1,050 mm diameter water supply aqueduct;
- five underground storage reservoirs with a combined approximate capacity of 48,000 cubic metres
(48 million litres);
- three water towers with a combined approximate capacity of 11,200 cubic metres (11.2 million
litres);
- approximately 542 kilometres of buried watermain with a diameter < 900 mm;
- approximately 4,062 watermain valves;
- approximately 2,698 fire hydrants; and
- approximately 41,653 water services and water meters.
The source of Guelph’s drinking water is a series of 21 operational groundwater wells and a shallow
groundwater collector system; this system consists primarily of true groundwater sources, with some
“groundwater under the direct influence of surface water with effective filtration” (GUDI-WEF) sources (i.e.
Carter Well field, Arkell 1 and the Glen Collectors). The Guelph Drinking Water System uses 12 per cent
1 NSF/ANSI Standard 61: Drinking Water System Components -- Health Effects
Annual and Summary Report
Page 4 of 77
Sodium Hypochlorite (that is NSF 602 certified) for primary disinfection at 10 locations and for multi-
barrier primary disinfection at three locations. At three locations, ultraviolet light is also applied as part of
multi-barrier primary disinfection. At two locations, NSF 60-certified sodium silicate is used for aesthetic
purposes to sequester dissolved iron and manganese. In total, Water Services operates and maintains 31
facilities for water. These facilities perform the following functions: sources, supply, treatment, storage or
transfer.
The replacement cost of the entire system (excluding Gazer Mooney Subdivision Distribution System) is
estimated to be $541.5 million or approximately $4,400 per capita. The majority of Guelph Drinking Water
System operations are funded directly from the sale of water, with minor additional funding through
government grant programs. Property taxes are not used to fund operation or maintenance of the system.
From Jan. 01 to Dec. 31, 2014, a total of 16,594,145 cubic metres (16.6 billion litres) of water was
treated and pumped to the system. The average daily water demand was 45,463 cubic metres (45.5
million litres). The highest daily use of water occurred on June 17, when 52,614 cubic metres (52.6 million
litres) of water was pumped. The minimum day production of water was 32,644 cubic metres (32.6 million
litres) and occurred on Dec. 26, 2014.
From Jan. 1 to Dec. 31, 2014, all regulatory microbiological and chemical quality samples were taken by
certified operators and tests performed by accredited, licensed laboratories on water samples collected
throughout the drinking water system. These tests include both regulatory and operational testing – in
most cases only regulatory reporting is included in this report. In all cases, the drinking water supplied to
all customers was confirmed safe and the water was of higher quality than all Ontario and Canadian
health-related guidelines.
The Guelph Drinking Water System is defined as a large residential system operated under the regulatory
requirements of the Safe Drinking Water Act and the Ontario Water Resources Act (accessed at
http://www.e-laws.gov.on.ca). The Guelph Drinking Water System operated under Municipal Drinking
Water Licence (MDWL) 017-101 (issue number 5 and 6) and the Drinking Water Works Permit (DWWP)
017-201 (issue number 3, 4, and 5).
The MDWL and the DWWP describe system-specific requirements that are supplementary to provincial
regulations and act as licences for water supply and distribution operations. These documents outline
specific conditions and requirements regarding operation, maintenance and upgrades that are required by
the system and are considered regulatory in nature. These documents are available by request for viewing
at 29 Waterworks Place, Guelph.

Gazer Mooney Subdivision Distribution System
The Gazer Mooney Subdivision Distribution System is a Class 1 Distribution Subsystem that serves
approximately 200 people, and is owned by the Township of Guelph/Eramosa. The system is operated by
Water Services by a legal agreement that was last signed by representatives of the City of Guelph and the
Township of Guelph/Eramosa on July 30, 2009. The terms of the agreement apply until May 31, 2019. All
of the water for the Gazer Mooney Subdivision Distribution System is supplied from the Guelph Drinking
Water System. All water is treated to provincial standards in the Guelph Drinking Water System and no
further treatment chemicals are added to the Gazer Mooney Subdivision Distribution System.
All new distribution infrastructure components meet NSF 61 requirements or approved equivalents and are
installed and maintained in accordance with approved industry standards. The system is fully metered.
The Gazer Mooney Subdivision Distribution System is comprised of the following infrastructure:
- approximately two kilometres of buried watermain with a diameter < 900 mm;
- approximately six watermain valves;
- approximately six fire hydrants; and
- approximately 72 water services and water meters.
The cost of construction of the Gazer Mooney Subdivision Distribution System was listed as $197,933 in
1980.
The Gazer Mooney Subdivision Distribution System is considered a small residential system and is
operated under the regulatory requirements of the Safe Drinking Water Act and the Ontario Water
Resources Act which may be found at http://www.e-laws.gov.on.ca.
The Gazer Mooney Subdivision Distribution System operated under Municipal Drinking Water Licence No.
104-103 (issue number 1), and Drinking Water Works Permit No. 104-203 (issue number 1). These
documents are available by request for viewing at 29 Waterworks Place, Guelph and at Township of
Guelph/Eramosa, 8348 Wellington Rd. 124, Rockwood.

Summary Water Services Report
a) Incidents of Regulatory Non-Compliance
This section describes all incidents of non-compliance (excluding those defined as “Adverse Water Quality
Incidents” (AWQI) reported in Section B of this report).
Guelph Drinking Water System
There were no incidents of non-compliance associated with the Guelph Drinking Water System in 2014
(Jan. 01 to Dec. 31).
The results of the 2014 Ministry of the Environment and Climate Change (MOECC) Annual Inspection
Report for the Guelph DWS and Gazer Mooney SDS are still pending.
Gazer Mooney Subdivision Distribution System
There were no incidents of non-compliance associated with the Gazer Mooney Subdivision Distribution
System in 2014 (Jan. 01 to Dec. 31).
The results of the 2014 Ministry of the Environment and Climate Change (MOECC) Annual Inspection
Report for the Guelph DWS and Gazer Mooney SDS are still pending.
b) Adverse Water Quality Incidents
This section describes all “Adverse Water Quality Incidents” (AWQI). This term refers to any unusual test
result from treated water that does not meet a provincial water quality standard, or situation where
disinfection of the water may be compromised. An adverse water quality incident indicates that on at least
one occasion and at a certain instance in time, a water quality standard was not met. On average, the
Guelph Drinking Water System processes four to five AWQI’s annually.
The process of water quality sampling and testing can result in false positive results for contaminants;
these results can be caused by contaminated sampling containers and equipment, sampling technique,
sample handling and transportation, and sample analysis. In almost all cases, mandatory follow-up
sampling and analysis confirms that contaminants are not present in the water provided to customers.
Please note: Any residential tap lead sample results collected as per the Regulatory Lead Sampling
Program above 10 µg/L are tracked and reported separately to the Public Health Unit, the Ministry of the
Environment and Climate Change (MOECC) and the customer, and will be addressed as per the City’s Lead
Reduction Plan. The Regulatory Lead Sampling program has been replaced with the Lead Reduction Plan
(LRP) – see Section J for more information.
Guelph Drinking Water System
From Jan. 1 – Dec. 31, there were three adverse water quality incidents (AWQI’s #115902, #116157,

c) Deviations from Critical Control Point (CCP) Limits and Response Actions
This section describes any deviation from essential steps or points in the drinking water system at which
control can be applied to prevent or eliminate a drinking water hazard or to reduce it to an acceptable
level. These essential steps or points in the system are known as critical control points (CCP). The CCPs
are used to identify control measures that are in place to address hazards and hazardous events. These
CCPs are in part stipulated by regulation and in part derived through risk assessment of the Drinking
Water System.
Water Services’ Critical Control Points include:
- primary disinfection,
- secondary disinfection, and
- backflow prevention.
Additional information (e.g. critical control limits and response actions) is included in Appendix “A” in the
“Summary of Critical Control Points and Critical Control Limits”.
Deviations from the CCPs are reported to both the Owners and Top Management, and are summarized in
the tables included in Section B of this report. There was one confirmed deviation from CCP Limits in 2014
(described in Table 1 as AWQI #120786).
d) The Efficacy of the Risk Assessment Process
This section confirms the occurrence of reviews of the risk assessment process to determine the
effectiveness of the process in identifying and appropriately assessing the risk of hazardous events and
hazards, and in identifying the appropriate control measures, critical control points (CCPs) and related
critical control limits (CCLs).
5 The aesthetic objective for sodium in drinking water is 200 mg/L. The local Medical Officer of Health should be notified when the
sodium concentration exceeds 20 mg/L so that this information may be communicated to local physicians for their use with patients
on sodium restricted diets.

e) Internal and Third-Party Audit Results
This section describes any of the audit outcomes identified to date that require follow-up actions.
6 Risk Ratings are based on the risk calculation (likelihood rating x consequence rating), as included in the "QMS 08 Risk Assessment
Outcome" document: "Low" risk: 1 to 5; "Moderate" risk: 6 to 11; "High" risk: 12 or higher
7 Cells with GREEN highlights indicate that Water Services has determined there are sufficient control measures to adequately
control the risks. Items highlighted in YELLOW and RED indicate risk areas that are not sufficiently addressed through existing
control measures, and require additional work. + - Improvement being made
Annual and Summary Report

Internal auditing and third-party auditing is performed to fulfill the mandatory requirements of the
Drinking Water Quality Management Standard (DWQMS). The internal audit is completed using trained
internal staff. The purpose of audits is to evaluate the level of conformance of Water Services to the
DWQMS. Audits identify both conformance and non-conformance with the Standard as well as
opportunities for improvement.
The 2014 internal process audits were completed on May 15 to 23, 2014. Internal audit findings are
related to QMS orientation training updates for current and any new staff (QMS 04). Various opportunities
for improvement suggested by staff were also noted in the internal audit report. The next scheduled
internal audit will take place in January 2015 so that there is a separation between annual internal and
external audits. The month of December will be targeted in the future as the new annual internal audit
period. This will also allow proper time for following up on corrective actions and opportunities for
improvement. It will also present the opportunity to verify effectiveness of actions taken to address
findings between internal and external audits.
The 2014 third-party external on-site audit was completed on Jun. 10 to Jun. 12, 2014. There were no
nonconformities identified during this audit. Noted opportunities for improvement by the auditor were
related to improving the following processes: communications (QMS 12); and tracking improvement items
(QMS 21). These opportunities for improvement will be followed-up on by the auditor at the next on-site
audit in Jun. 9-11, 2015.
f) Results of Emergency Response Testing
Emergency response testing is regularly completed as a component covered by the Water Services’
Quality Management System (QMS) to ensure that Water Services maintains a reasonable readiness to
deal with emergencies. The ability to deal with emergencies is critical in demonstrating that Water
Services has taken a diligent approach to operating the Guelph Drinking Water System.
Feedback from this testing and from actual events is gathered during debriefing sessions and
improvement items are incorporated into the Water Services Emergency Plan and /or daily operations.
During the winter of 2014, Guelph experienced seventy-six frozen services (with sixty temporary lines
installed), the greatest number in one season since 1993. Typically, there are six frozen service lines in a
winter season. For each frozen service event, immediate actions were taken by staff to prevent any
further complications. Water Services staff continue to work on closing corrective actions initiated from
debriefing sessions related to Winter 2014’s frozen services and ice storm events that occurred in 2013.
Table 4 includes the dates of Completed Emergency Response Tests for the past three years.

g) Operational Performance and Statistics
The following section describes Operational performance statistics within Water Services that includes:
− 2014 Totalized Pumpages as per the Municipal Drinking Water Licence and Permits to Take Water;
− 2014 Instantaneous Flows as per Permit to Take Water requirements;
− Water Production and Population;
− 2014 Collector Flows; and
− Other Operational Performance Data.
2014 Totalized Pumpages and Instantaneous Flows (Jan. 01 to Dec. 31).
The Safe Drinking Water Act (SDWA) and the Ontario Water Resources Act (OWRA) each require that
operating authorities record and report both water takings as governed by Permits to Take Water
(PTTWs), and water being supplied to the City of Guelph.
Summaries of total water pumped, instantaneous flows and capacity (flows and volumes compared to
rated capacities) by the City of Guelph can be found in Appendix “C” – Total Water Pumped and
Instantaneous Flows.
8 “Water Shortage” and “Damage to Main Supply...” hazardous events are being deferred until the lessons learned and corrective
actions from the 2013 and 2014 events are adequately addressed.

2014 Totalized Pumpages (Jan. 01 to Dec. 31).
Figure 3 below depicts the water pumpage rate in cubic metres per day (m3/day) that is averaged each
week.
Figure 3: 2014 Totalized Pumpages (Jan. 01 to Dec. 31)
Water Services processed 16,594,145 cubic metres (16.6 billion litres) of water to the distribution system
in 2014 (Jan. 01 to Dec. 31). This represents 2.4 per cent more water being supplied to the distribution
system in 2014 as compared to the same time period in 2013 and 0.5 per cent more water than in 2012.
The average daily water demand was 45,463 cubic metres (45.5 million litres). The maximum day
production of water in 2014 was 52,614 cubic metres (52.6 million litres) and occurred on Jun. 17, 2014.
The minimum day production of water in the same time period was 32,644 cubic metres (32.6 million
litres) and occurred on Dec. 26, 2014.
Possible explanations for water use changes include: economic conditions (“an economic downturn”),
seasonal variations (sufficient precipitation that is conducive to lower outside water use), conservation
program outreach and education, and water loss associated with infrastructure demand due in part to the
harsh winter (frozen services and watermain breaks).

Collector Flows
The Arkell Spring Grounds Collectors (“Collectors”), one of Guelph’s many water sources, consist of a
gravity-fed under-drain system that collects shallow overburden groundwater. This system has been in
use since the early 1900s and can represent as much as 40 per cent of the total city-wide daily water
production. When the output of this source is reduced, Water Services is required to make up the
difference from other water supplies. Throughout the year, the production from this water supply varies
from an approximate low of 4,000 cubic metres (4 million litres) up to an approximate high of 20,000
cubic metres (20 million litres) per day.
The Collectors can also be used as a measurable index of the state of the environment (i.e. very dry to
very wet as they respond to rainfall and other environmental conditions). The volume of water that the

Collectors produce is one of the benchmarks used in the decision-making process to determine the
appropriate level for the City’s outside water use program.
Seasonally, between April 15th and November 15th, the City has a PTTW (permit to take water) that allows
water to be pumped from the Eramosa River to a pond and trench-based “Recharge System”. In the
Recharge System, the river water is filtered in-situ through the ground and approximately 50 per cent of
the flow is captured in the Glen Collector System. It should be noted that the Recharge System has not
been utilized from 2011 through 2014 in order to accommodate the Arkell OTP/AMP (Operational Testing
Plan / Adaptive Management Plan) which is a condition of the Arkell Well Field PTTW (Permit to Take
Water).
The productivity of the Collectors can also be used as a predictive tool. If the production volume from the
Collectors is low, then it can be assumed that other water supplies would be needed to make up the
difference. This may alter how regular maintenance is performed as well as the urgency with which repairs
are made to supplies that unexpectedly go off-line as they may be needed to supplement overall
production for the City when the Collector System is unable to produce a sufficient supply.
The Collectors have produced 3,076,164 cubic metres (3.0 billion litres) of water in 2014 (Jan. 01 to Dec.
31). This represents 13.6 per cent more water as compared to the same time period in 2013 and 42.7 per
cent more water than in 2012.
Note: This information should not be used in isolation as a predictive tool.
For a visual representation, please refer to Figure 5: 2014 Glen Collector Volumes (Jan. 01 to Dec. 31):
2014 Glen Collector Volumes (Jan. 01 to Dec. 31).

h) Raw and Treated Water Quality – Guelph Drinking Water System
This section describes the water quality monitoring, both regulatory and operational, that has been
completed in 2014 (Jan. 01 to Dec. 31).
Annual and Summary Report
Page 20 of 77
Water Quality Review – Guelph Drinking Water System
Under the Safe Drinking Water Act (SDWA), municipalities are required to monitor both the raw and
treated quality of the source water supplied. This monitoring is performed for both regulatory compliance
and due diligence and is expected to identify any changes within the treated water as well as in raw
source waters.
A note about all tables included in this section:
1. All regulated chemical parameters where values above the lab’s MDL (minimum detection limit)
have been detected in the City of Guelph’s treated water sources are underlined indicating a
hyperlink to an Excel Workbook in Guelph’s electronic document management system (EDMS).
Note: EDMS is available for internal use only. The workbook contains a definition of the parameter
and an Excel worksheet for each treated source where the parameter has been detected with
values for all sample results from Jan. 01, 2007 to Dec. 31, 2014. This database is used to closely
track the instances of the identified chemical parameters and therefore provide time for planning /
budgeting if treatment or an alternative supply is eventually required due to the presence of a
given parameter. The database is updated semi-annually.
2. Tabulated values are from best available information at the time of table creation. While the values
above satisfy the regulatory minimum regulatory requirements, Water Services performs many
additional operational tests not listed in this report.
3. All acronyms and initialisms included in tables are described in Appendix “E” – Index of Terms,
Acronyms and Initialisms.
The following section summarizes daily Distribution free chlorine residual test results required by O. Reg.
170/03 Schedule 7-2 where “secondary disinfection” is provided for the period of Jan. 01 to Dec. 31,
2014. The Verney Tower sample point is used to represent the water quality provided by the Zone One
distribution system pressure zone and the Speedvale Tower sample point represents the water quality
provided by Zone Two for the purposes of the regulation. Please note that the City of Guelph takes
additional “operational” daily Distribution samples and tests for free chlorine residual in order to better
monitor the free residual in the Distribution System and respond accordingly. There was no instance of an
adverse result in 2014 (Jan. 01 to Dec. 31):

As a part of the Guelph Drinking Water System’s Municipal Drinking Water Licence (MDWL), Guelph Water
services is required to assess twice annually Arkell Well #1 and The Arkell Collector Systems which are
both groundwater under the influence of surface water with effective in situ filtration (GUDI-WEF). The
purpose of the assessment is to ensure that the sources continue to meet the GUDI-WEF source water
characteristics as outlined by the MOECC. Sampling was performed on these two water sources in the
spring of 2014. The sources continue to meet the GUDI-WEF source water characteristics.

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 6-5 - “Continuous Monitoring”
Results Summary
Water Services utilises over twenty regulatory and operational continuous monitoring devices to measure
water quality. Each regulatory device has controls associated with it such that in the event that the device
detects that a measured value is outside the acceptable parameters for that location, the device causes an
alarm to be sent to an operator for immediate response (24 hours per day seven days per week) and
either automatically shuts down the station or activates a second alarm for immediate operator response.
Both the minimum allowable levels (if applicable) and the target values for Water Services regulatory
continuous monitoring devices are listed below. The target values represent a safety margin to help
ensure that regulatory requirements are satisfied at all times. Please note that with the exception of the
values reported in the AWQI section of this report if applicable (Section B), continuous monitoring values
all fell within acceptable regulatory standards in 2014 (Jan. 01 to Dec. 31).

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 13-6 and 13-7, “Three Month”
Sampling Results Summary
In 2014, all operational Treated Sources were sampled and analyzed for Schedule 13-6 and 13-7
parameters as per O. Reg. 170/03.
Regulation 170/03, Schedule 13-6 requires a minimum of one distribution sample taken from the
Distribution System where THM’s (trihalomethanes) are most likely to develop (locations with high
retention times). Water Services uses Speedvale Tower and Clair Tower for this purpose in the Guelph
Drinking Water System. The Maximum Allowable Concentration (MAC) for THM’s is 0.1 mg/L. However, for
this parameter the MAC uses a running annual average of quarterly samples.
The results of the running average value for THM’s for all related Distribution System samples in 2014
(Jan. 01 to Dec. 31) is below the ½ MAC (half of the maximum allowable concentration).
All operational Treated Sources were sampled and analyzed for Nitrates and Nitrites as per Regulation
170/03, Schedule 13-7. There was no instance of an adverse result in 2014. Raw sampling results are also
shown in Table 13 (ODWQS do not apply to these values).

In 2013, all operational “Treated Sources” were sampled and analyzed for Schedule 23 parameters as per
O. Reg. 170/03. All of the City of Guelph’s treated ground water sources are on a three year sampling
schedule. F.M. Woods’ Station is the exception and is sampled on the annual surface water schedule due
to the fact that three of the eight sources that supply F.M. Woods are GUDI-WEF sources (the Carter Well
field, Arkell 1 and the Arkell Glen Collectors).
The results of the Schedule 23 inorganic parameter analysis in 2013 were all under the ½ MAC (half of the
maximum allowable concentration) and the majority were under the laboratory’s MDL (minimum detection
level). Please refer to the section entitled “O. Reg. 170/03 Schedule 23 Results Summary” included in
Appendix “B” for more information.
The next scheduled “Three Year” Schedule 23 sampling event takes place in the third quarter of 2016.
The results of the Annual Schedule 23 inorganic parameter analysis in 2014 for F.M. Woods’ Station were
all under the ½ MAC (half of the maximum allowable concentration) and the majority were under the
laboratory’s MDL (minimum detection level).

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 24 Results Summary
If sampling for a particular schedule’s parameters (e.g. Schedule 23 and 24) did not occur within the
calendar year of the report, then the most recent values are required to be included in the report for
reference.
In 2013, all “Treated Sources” were sampled and analyzed for Schedule 24 parameters as per O. Reg.
170/03. All of the City of Guelph’s treated ground water sources are on a three year sampling schedule.
F.M. Woods’ Station is the exception and is sampled on the annual surface water schedule due to the fact
that three of the eight sources that supply F.M. Woods’ are GUDI-WEF sources (the Carter Well field,
Arkell 1 and the Glen Collectors).

The results of the Schedule 24 organic parameter analysis in 2013 were all under the ½ MAC (half of the
maximum allowable concentration) and the majority were under the laboratory’s MDL (minimum detection
level). Please refer to the section entitled “O. Reg. 170/03 Schedule 24 Results Summary” included in
Appendix “B” for more information.
It should be noted that values for TCE (trichloroethylene) at Membro and Emma have on occasion, crested
the ½ MAC value of 0.0025 mg/L and as a result Water Services has moved to an “Increased Frequency
Sampling Plan” as required by Regulation 170/03 - 13-5 which requires that sampling for this parameter
be sampled every “three months” until two consecutive sample results are below the ½ MAC value. As a
precautionary measure, Water Services samples both raw and treated sources on a monthly schedule at
Membro and Water. All other sources, both raw and treated, are sampled annually (minimally) for VOC’s
(Volatile Organic Carbons) through a “Guelph VOC Scan” in order to better track parameters such as TCE
via more data. Currently, TCE is above the MDL but below the ½ MAC at Membro, Water Street, Park and
Paisley* POE.
*The TCE at Paisley POE can be attributed to Emma, Membro, Water Street and Park feed water via the
Paisley Reservoir low zone fill line as VOC analysis from 2007 to the present on Paisley raw water shows
values below the lab’s MDL (minimum detection level) for all parameters.
The next scheduled “Three Year” Schedule 24 sampling event takes place in 2016.
The results of the Annual Schedule 24 organic parameter analysis in 2014 for F.M. Woods’ Station were all
under the ½ MAC (half of the maximum allowable concentration) and the laboratory’s MDL (minimum
detection level).

Sampling Results Summary
If sampling for a particular schedule’s parameters (e.g. Schedule 23 and 24) did not occur within the
calendar year of the report, then the most recent values are required to be included in the report for
reference.
In 2014, all operational “Treated Sources” were sampled and analyzed for the Schedule 13-9 Fluoride
parameter as per O. Reg. 170/03. In 2014, Fluoride (naturally present) was detected at all treated
sources; the analytical results were all under the MAC (maximum allowable concentration). The values in
Table 17 reflect the 2014, Schedule 13-9 sampling regime. Sodium, however, is sampled on a more
frequent basis (annually) than the Schedule 13-8 requirement. Due to the fact that at every treated
source with the exception of F.M. Woods (currently), sodium levels are above the lower reportable limit of
20 mg/L. The increased frequency of sampling provides more data in order to better establish sodium
value trends. Sodium results for 2014 can be referenced in “
Table 18: City of Guelph General Chemistry Selected Results Summary”. This data is provided to
Wellington-Dufferin-Guelph Public Health.

Chemical Analysis Package). This body of data can be used to answer “customer inquiries” as well as
inquiries from Water Services staff and consultants in terms of treatment upgrades et cetera.
Please note that Schedule 23 parameters are also part of the “Annual General Chemistry Sampling
Regime” and therefore the values in the “General Chemistry Results Summary” section in Appendix “B”
include a repetition of the relevant data from the Schedule 23 Table. The “General Chemistry Results
Summary” lists the total number of samples analyzed for these parameters in 2014.
In 2014, all operational “Treated Sources” were sampled and analyzed for general chemistry parameters.
Please refer to the “General Chemistry Results Summary” in Appendix “B” for the full list of parameters.
Table 18 highlights specific parameters due to their presence / significance within the water supply.

i) Treated Water Quality – Gazer Mooney Subdivision Distribution System
This section describes the Regulatory water quality monitoring that has been collected in the Gazer
Mooney Subdivision Distribution System in 2014 (Jan. 01 to Dec. 31, 2014). For regulatory sampling
schedules that do not occur in 2014 related to the Gazer Mooney System, the most recent historical data
is listed.
16 Where supplies contain naturally occurring fluoride at levels higher than 1.5 mg/L but less than 2.4 mg/L, the Ministry of Health
and Long Term Care recommends an approach through local boards of health to raise public and professional awareness to control
excessive exposure to fluoride from other sources.

Water Quality Review - Gazer Mooney Subdivision Distribution System
Under the Safe Drinking Water Act (SDWA), municipalities are required to monitor both the raw and
treated quality of the source water supplied. This monitoring is performed for both regulatory compliance
and due diligence and is expected to identify any changes within the treated water as well as in the raw
source waters.
A note about all tables included in this section:
1. All regulated chemical parameters where values above the lab’s MDL (minimum detection limit)
have been detected in the City of Guelph’s treated water sources are underlined indicating a
hyperlink to an Excel Workbook in Guelph’s EDMS (electronic document management system).
Note: EDMS is available for internal use only. The workbook contains a definition of the parameter,
an Excel worksheet for each treated source where the parameter has been detected with values for
all sample results from Jan. 01, 2007 to Dec. 31, 2014. This database is used to closely track the
instances of the identified chemical parameters and therefore provide time for planning / budgeting
if treatment or an alternative supply is eventually required due to the presence of a given
parameter. The database is updated quarterly.
2. Tabulated values are from best available information at the time of table creation. While the values
above satisfy the regulatory minimum regulatory requirements, Water Services performs many
additional operational tests not listed in this report.
3. All acronyms and initialisms included in tables are described in Appendix “E” – Index of Terms,

Treated Water Quality Statistics – O. Reg. 170/03 Schedule 13-6, “Three Month” Sampling
Results Summary
In 2014, Gazer Mooney Subdivision Distribution System was sampled and analyzed for Schedule 13-6
parameters as per O. Reg. 170/03:
Regulation 170/03, Schedule 13-6 requires a minimum of one distribution sample taken from the
Distribution System where THM’s (trihalomethanes) are most likely to develop (points with high retention
times). The MAC for THM’s is 0.1 mg/L. However, for this parameter the MAC uses a running annual
average of quarterly samples.
The results of the running average for the Gazer Mooney Subdivision Distribution System samples in 2014
(Jan. 01 to Dec. 31) is below the ½ MAC (maximum allowable concentration).

j) Status of Ongoing and Emerging Water Quality, Supply and Distribution
Initiatives
This includes summaries and updates related to the implementation of the:
- Water Conservation and Efficiency Strategy & Water Supply Master Plan;
- Source Water Protection Plan; and
- Lead Reduction Plan.
Water Conservation and Efficiency Strategy & Water Supply Master Plan Updates
Water Services continues to implement recommendations of the 2009 Water Conservation and Efficiency
Strategy. The Water Conservation team produces an annual report on The Water Conservation & Efficiency
Program, and the last update, “2014 Annual Progress Report” is included in Appendix “D”. Below is a
summary of 2014 aspects of the Water Supply Master Plan that were implemented between Jan. 1 to
December 31, 2014 to support sustainable water resources management:
- The City of Guelph celebrated Canada Water Week with the second annual H2O GO Festival, a large
scale engaging celebration of water. Collaborating with community partners, H2O GO welcomed the
contributions of local businesses, community organizations, experts, performers and families. The
event attracted over 400 participants of all ages to City Hall for water-themed presentations, live
performances of music and dance, interactive exhibits, games about water and artistic children’s
activities. In addition to these initiatives, nine local water-themed public events were hosted
throughout the City during the month of March in support of Canada Water Week and World Water
Day. The festival was held on the same day as and within walking distance of two other
sustainability themed events, Guelph Environment Leadership’s EcoMarket and Transition Guelph’s
Resilience Festival. At all events, participants were encouraged to attend neighbouring events,
18 The aesthetic objective for sodium in drinking water is 200 mg/L. The local Medical Officer of Health should be notified when the
sodium concentration exceeds 20 mg/L so that this information may be communicated to local physicians for their use with patients
on sodium restricted diets.
Annual and Summary Report

thereby creating a festive spirit in the downtown core that achieved the goal of engaging the public
in learning about water in Guelph. In addition to these events, Water Services launched a week-
long social media engagement campaign about water protection, conservation and enjoyment
featuring items on the importance of the Grand River watershed to this region in accordance with
the week’s theme of “Watersheds 101”. Also part of Canada Water Week, the Guelph Public Library
and Guelph Water Services Department partnered to host ‘Water Wednesdays’ at two local library
branches. These events offered water-themed educational programming for all ages, including
interactive games and activities designed to inform local youth of Guelph’s water sources, steps
taken to treat our community’s drinking water, and the importance of conservation and protection
of our precious water resources.
- On June 9th, 2014, approximately 800 students from Guelph elementary schools participated in
H2Awesome, a day-long event celebrating water conservation and the importance of water in our
daily lives. The event featured well-known water advocates Alex and Tyler from The Water
Brothers, the TVO eco-adventure documentary series. Also key to the event was a variety of 17
different curriculum linked workshops on various themes, including arts, science, and technology,
enabling students to pick their own specific learning venue. The event was a successful
collaborative partnership project with the City of Guelph, Wellington Water Watchers, the Upper
Grand District School Board, and the University of Guelph.
- Review of City’s Outside Water Use By-law was completed in March 2014 with Guelph City Council’s
endorsement of the revised Outside Water Use By-law and associated program amendments.
Terms of the revised by-law came into effect on April 1, 2014. For more information on the revised
by-law and by-law review process please visit guelph.ca/owureview.
- Tender for the construction of the integration of rainwater harvesting within Guelph Transit’s bus
wash was completed in June 2014 with construction of process completed on October 8, 2014.
Through the integration and use of harvested rainwater for the final rinse phase of this process,
potable water and chemical wash needs are anticipated to be reduced by 40 per cent per bus. This
project is made possible through funding provided by the Province of Ontario’s Showcasing Water
Innovation Program.
- Field implementation of six district metered areas (DMAs) continued throughout early 2014 as part
of the City’s Leak Detection Program. These works, supported by the Province’s Showcasing Water
Innovation Program, will allow the City to proactively monitor and respond to leakage at the time
of leak occurrence in defined DMA locations, as well as retain on a ongoing basis water loss savings
previously reclaimed. In building upon these innovative works, detailed hydraulic modelling and
prioritization of an additional 21 DMAs was initiated in January of 2014 with these additional DMAs
to be implemented over the next 4 year period (2015-2018).
- Annual Leak Detection Program launched in August 2014 including sounding and correlation of all
metallic watermains within the City’s distribution system, encompassing 287km of linear
infrastructure. This study concluded in October 2014 with 3 watermain breaks of significance
identified through the study. Water savings following remediation of this infrastructure is
anticipated to be approximately 1,024 m3/day based on field water loss estimates.
Annual and Summary Report
Page 34 of 77
- Operation and optimization of existing conservation programs continued (e.g. Residential Rebate
Programs, Blue Built Home, ICI Capacity Buyback Program), equalling 230 m3/day in collective
demand reductions in 2014.
Source Water Protection Plan
This section includes summaries on Guelph’s Source Water Protection Program initiatives and
ongoing work related to preparation for implementation.
The Lake Erie Source Protection Committee submitted the Proposed Grand River Source Protection Plan
to the Ministry of the Environment and Climate Change (MOECC) for review and approval. This Plan
includes a number of proposed policies to manage significant drinking water threats (identified in the
Assessment Report) for the City of Guelph. The MOECC is presently reviewing Source Protection Plans
that have been submitted from across the province. The Lake Erie Source Protection Committee
anticipates that the Grand River Source Protection Plan will be approved by the Minister in 2016.
Currently, City staff are working on: the development of education and outreach materials for
stakeholders, development of guidelines for the preparation of risk management plans, and working
with internal City of Guelph departments to ensure conformance with the proposed policies in the
Source Protection Plan. The City is also assessing the data management and information needs that
will be required to administer the program once the Source Protection Plan is approved.

Arkell Springs Forest Stewardship Project
The Arkell Spring Grounds cover an area of 804 acres. The area is comprised of old and new forested
areas, which makes it necessary for monitoring, maintenance and new planting plans. The objective of the
Arkell Springs Forest Stewardship Project is to manage past plantings and prevent losses while monitoring
general forest health. Delicate forest stands require continued maintenance and observation to ensure the
prevention of any unnecessary and undesired losses.
Since 2007, the Community Environmental Leadership Program (CELP), on a volunteer basis has planted
16,500 trees on 18 acres, and Bartram Woodlands (on-site contractor) has planted 21,200 trees on
another 16 acres. In addition, funding was secured through the Ontario Ministry of Natural Resources’ 50
Million Tree Program—part of the United Nations Billion Tree Campaign. The Ontario portion of the fund is
committed to planting 50 million trees by 2025. This funding allowed the City to plant 5,245 seedlings in
fields adjacent to Watson Road.
The many benefits of the Arkell Springs Forest Stewardship Project include the creation of a diverse and
functioning forest cover, maintenance and re-generation of older forested areas on the property,
protection and recharge of underground aquifers, prevention of undesirable surface water runoff and
flooding into local waterways, and regulation of the flow of water.
The characteristically strong organic matter component of soils within a forest allows for added infiltration
and precipitation to recharge the underlying aquifer. The filtration ability of a forest system results in
additional methods to filter water.
Annual and Summary Report
Page 35 of 77
This multiple barrier approach results in the highest possible quality of water to supply Guelph’s drinking
water system. Forest systems also extend the longevity of the existing snow pack by stabilizing the
temperature of the ground and limiting the evaporative impact of the sun. This ensures water resources
are re-absorbed into the underlying aquifer where they are needed rather than contributing to damaging
runoff and flooding.
Lead Reduction Plan
The City submitted a Lead Reduction Plan (LRP) to the MOECC in April 2011 as a result of two rounds of
legislated lead sampling indicating that more than ten percent of residential samples taken exceeded the
ODWQS of 10 μg/L. The LRP was submitted in lieu of a Corrosion Control Plan (as outlined in O.Reg
170/03 Sched. 15) after evaluation of both chemical corrosion control and physical replacement, as well
as extensive consultation with the MOECC, and Wellington-Dufferin-Guelph Public Health. The MOECC
formally approved the City of Guelph’s LRP and application for full regulatory relief from the lead sampling
requirements of Schedule 15.1 on March 21, 2012.
In January 2014, based on the success of the program, the City formally requested an amendment to the
City’s Drinking Water Licence to remove the references to the regulatory requirements and reporting
associated with the City’s lead program. Lead service line replacements have permanently reduced the
number of homes exceeding the ODWQS for lead to below the Schedule 15.1 regulations. Regulatory relief
from Schedule 15.1 (in its entirety) in exchange for the continued operational programs outlined in the
LRP, was granted in Schedule D of the City’s Municipal Drinking Water Licence issue number 6.
This section provides a summary of the aspects of the LRP.
The following table presents summary results for lead sampling in the Guelph Drinking Water System as
per our Lead Reduction Plan for the period of Jan. 1 to Dec. 31, 2014:

Lead Sampling
Lead sampling is conducted to identify the presence of lead service lines (LSL) and to monitor lead levels
following a LSL replacement. For the period of Jan. 1 to Dec. 31, 2014, 89 Lead Verification samples were
taken. Of these sample results, 6.7% were above 5 µg/L indicating presence of a lead service line. Of all
verification samples, 5.6% also exceeded the ODWQS of 10 µg/L. Lead samples are collected before and
after a LSL replacement has been undertaken. There were 18 resamples collected in order to monitor lead
levels post-replacement. Based on sample results to date, regulatory compliance is expected at individual
sites that have undergone a full LSL replacement or where there is no lead remaining in the service line.
Lead Service Line Replacements
There were 11 Lead Service Line (LSL) replacements undertaken in the City between Jan. 1 to Dec. 31,
2014. These replacements include the following situations: i) Full LSL Replacement where both the City-
and private-side of the LSL is replaced, ii) Partial LSL Replacement where only the City-side of the service
is replaced and connected back to lead or a non-lead material on the private-side, and iii) Private LSL
Replacement where the private-side of the service is replaced and the City-side is known to be copper.
The next table presents a summary of all LSL replacements in the Guelph Drinking Water system for 2014
up to Dec. 31.

property.
23LSLs are replaced when discovered during planned street reconstruction activities.
Annual and Summary Report
Page 37 of 77
Privately Owned Lead Service Line Replacements
Since 2010, the City initiated has been providing two financial incentive programs to encourage
replacement of privately-owned LSL by reducing the financial burden to property owners. The grants cover
70 to 100 percent of the LSL replacement cost for homeowners. The Private Lead Water Service
Replacement Grant Program provides funding to homeowners to replace a confirmed privately owned LSL
where the City-owned water service line is confirmed to be copper (i.e., City-side LSL was previously
replaced). The Full Lead Water Service Replacement Grant Program provides funding to homeowners to
replace a confirmed privately owned LSL in tandem with City-owned LSL replacement. From 2010 to Dec.
31, 2014, 185 privately owned lead service lines were replaced through the grant programs.

Grand Total to date - - - - 185
Targeted outreach regarding the Grant Programs is directed at all properties with known or suspected
privately-owned LSLs. The main barriers to privately owned LSL replacement for homeowners include
financial costs, disruption to property, and people who are unconcerned about the health risks of lead in
drinking water. Direct communications continued to be been tailored to address these barriers.
Encouraging replacement of privately-owned LSL by rental properties was identified as a significant
challenge for the Grant Programs. The City is not able to provide grant funding to commercial entities due
to the “bonusing” restrictions of the Municipal Act. In April 2012, changes were made to the Grant
Programs to allow rental properties that are not owned by a commercial enterprise (including property
management enterprises) to apply for a grant in accordance to the Municipal Act. Targeted communication
to property owners regarding this change has successfully increased uptake in the Grant Programs.

Annual and Summary Report
Page 38 of 77
Correspondence with the MOECC regarding the finalization of the updated Municipal Drinking Water
Licence and Drinking Water Works Permit took place over June and July, 2014. Final documents were
issued in August (MDWL) and September (DWWP) and expire in 2019.
Operational Testing Plan and Adaptive Management Plan (OTP / AMP)
The purpose of the OTP / AMP is to carry-out a detailed assessment of both the Arkell area aquifer and
pumping conditions related to the aquifer to determine a sustainable capacity with respect to
environmental considerations in the area. It is anticipated that the OTP / AMP will take place over
approximately three years. Additional details may be obtained by contacting Water Services. Annual
monitoring reports providing reporting on monitoring results for the previous year were provided in early
2012 and early 2013. As a result of two years of monitoring, Water Services requested an increase to the
Arkell Bedrock Wellfield Permit to Take Water which was granted by the MOE in October 2013. Water
Services is continuing to assess the sustainability of the bedrock water taking at the higher pumping rates
with the intention of modifying the monitoring requirements within the permit. Additional monitoring and
data collection / assessment is ongoing, and further extensive monitoring is being performed at Arkell Well
#15 to confirm its source water characteristic classification as groundwater.
GUDI (Groundwater Under the Direct Influence of surface water) Terms of Reference are under
review and may result in classification changes to source waters. The GUDI Terms of Reference are
expected in 2016.
Carter Monitoring Program
The Permit to Take Water for Carter Well requires that the Carter Wells be operated at increased levels in
conjunction with monitoring in the Torrence Creek Subwatershed. The purpose of the monitoring is to
attempt to quantify impacts within this subwatershed.
Water Supply Master Plan
Council unanimously voted to approve an update to the City’s 2007 Water Supply Master Plan on July
28th, 2014. This update forecasts and makes plans for water use and access to a safe and sustainable
water supply for our growing community—residential, industrial and commercial—over the next 25 years.
The Water Supply Master Plan update process involved extensive public consultation, input from a
Community Liaison Community, and feedback from agency representatives and local municipalities. The
update process also included a 30–day review period during which interested parties were invited to
provide comments and ask questions.
Conservation and demand management remain the key options for meeting our current and future water
supply needs, with new groundwater supplies from existing, offline wells, test wells and new wells inside
the city limits also helping to meet future needs. Other recommendations and options include
improvements to the water planning and approval process, a by-law to restrict new private groundwater
supply wells within the City limits, and a possible future treatment plant for a surface water supply from
Guelph Lake.

NSF 60/61 Standards that are listed in our MDWL and DWWP are

MOE has indicated that if we have inventory (such as meters or brass)
that meets the current standards, we will be able to use them up until
we renew our License (this year) after which we will have to comply with
the new standards regardless of existing inventory. This may impact our

n) The Results of Infrastructure Review
The review of infrastructure requirements is achieved by reviewing the needs of existing infrastructure and
of new infrastructure requirements. This review is carried out for the infrastructure needs of distribution
and supply & facilities.
Distribution Infrastructure Needs
On a regular basis (at monthly meetings), Guelph’s Engineering and Water Services review the condition
of supply and distribution infrastructure and review: inventory, age, CAPS (capital asset prioritization
system), criticality, soil type and diameter. From this evaluation, Engineering and Water Services develop
a list of priority projects that also considers the priorities of wastewater and road reconstruction projects
so that these projects can share the costs of excavation and rehabilitation. The priority list is updated
(with considerations included) and presented in Annual Operating Budget and the Tri-Annual Capital
Budget processes. New linear infrastructure reviews are primarily driven by Engineering Services.
Annual summaries of road reconstruction, sewer and watermain projects are identified on an
infrastructure map that is released early spring each year.
An Asset Update Report was prepared in 2012 to rate sustainability for various infrastructure programs
across the City. Water Services’ sustainability rating is A-.
Supply & Facilities Infrastructure Needs
On July 28th, Guelph City Council unanimously approved the Water Supply Master Plan update (linked to
news and document on Guelph.ca). The Master Servicing Study is another infrastructure plan that is
updated every five years and is used to identify new and replacement infrastructure priorities to include in
the budgeting process. The development of a Facility Master Plan is also in progress, along with new
initiatives related to property planning for expansions of facilities or to implement new facilities, as
required. The Owner (Council, CAO and Deputy CAO) is updated regarding any deficiencies or gaps.
Backflow Prevention Program
Preservation of drinking water quality within Guelph’s infrastructure is supported by the City of Guelph’s
Building Services and Guelph’s Backflow Prevention Regulations (“By-law”, Number (2008) – 18660). As
per the By-law, “Backflow” means the flowing back of or reversal of the normal direction of flow of water.
The By-law requires that no connections are made to the City’s water supply without the installation of a
backflow prevention device to isolate premises, sources, and zones to prevent cross-connections in every
building or structure where a City water supply or other potable water supply exists.
On a regular basis, Building Services provides the following “Backflow Report” included in the table below
that tracks the number of letters sent out regarding annual testing and re-surveying requirements of the
By-law.
The City of Guelph has a total of 2,652 properties (2,574 active and 78 inactive properties) that have a
total of 6,149 backflow prevention devices installed. Of the total, 1,860 buildings have premise isolation
and 944 buildings are without premise isolation (e.g. residential irrigation systems, plaza facility – plaza
Annual and Summary Report
Page 48 of 77
owner has premise isolation). New properties from Jan. 01 to Dec. 31: 23 with premise and 47 without
premise isolation.

Supply facilities are now task-based so that these designations remain the same
from year to year and the type of work is designated with the Work Order #.
Maintenance work orders now have four subcategories: emergency, urgent,
corrective and preventive. New tasks include Water Quality Monitoring for
SCADA Operator and for Non-Compliance Investigative Sampling. Operator-

14-06
Returned Speedvale Tower PLC
and heater to station power and
replaced unreliable UPS
The Speedvale Tower PLC and heater was returned to station power to prevent
communications to fail repeatedly. The unreliable UPS was also replaced in the
PLC cabinet.
14-07 Improved “Source and
Distribution Sampling Procedure”
The “Source and Distribution Sampling Procedure” was improved to include
three new elements: 1. Nitrile gloves while handling sample bottles and during
the sampling process; 2. Place the necessary empty sample bottles for the
sampling event (including a few extra) in plastic re-sealable zipper storage bags
within an appropriately sized cooler; 3. When a station POE Booster Pump must
be started prior to sampling, allow to run for a minimum of one hour before a
sample(s) is taken.
14-08 Improved University Setpoints
Since University’s contribution to overall volume and pressure is more relevant
at night, University’s fill and draw time cycles will be run in reverse at night.
This will help optimise the low zone performance overnight and keep Burke’s
station off.
14-09 Distribution Map Book in PDF
The Water Distribution Technician has created (in PDF) an electronically
searchable distribution map book. A new grid now exists so that all pages are
the same scale and at a scale that is easier to read than the previous books. On
the first page (of 195 pages) is the index map. Clicking on a grid on this page
will take you to that map page. In the bottom-right corner of each map page, is
a link to the “Index Map” on the first page.
14-10 Increased response to “Frozen
Services”
With the increase in frozen services this past winter (due to extreme cold
leading to deeper than average frost depth), staff spent considerable time
investigating frozen services, thawing service lines or installing temporary water
services where possible. A web page dedicated to answering frequently asked
questions was also developed.

auto logic was updated in SCADA so that when running Vertical Turbine Pumps
in Auto, duty pump 4 will no longer start – in order to meet electrical code legal
requirements.
14-13 Clarification of Well Minimum
Pumping Levels
Operations and Maintenance Manual sections that refer to the MPLs (Minimum
Pumping Levels) at a given site have been replaced by the Operators to reflect
the standard ‘3 metres above pump inlet’.
There are some Logbooks where the MPL is referenced on each page of the
‘Weekly P.M. Data Sheet’ – the Logbook electronic files were updated to reflect
the changes.
14-14
Various upgrades towards
possibility for Zone 2 “Closed
Pressure System”
Various upgrades towards implementation of the Zone 2 “Closed Pressure
System” includes installation of new equipment; diesel generators’ automatic
transfer switches wired and tested; training; pressure monitoring through
installation of data loggers at hydrants; and replacement of valves at Robertson
Booster Station inlet and point-of-entry. A draft control narrative for Paisley and
Robertson under a Zone 2 Closed Pressure System is also proposed.
14-15 Larger network cabinet
implemented
In order to accommodate growing computer & networking needs, the IT
department removed the main network cabinet from the Library to a new larger
network cabinet in the SCADA server room.
14-16 eRIS SCADA upgrade to new 1.2
release
New features in the 1.2 release are:
Upgraded Data Query tag selection interface
Upgraded Data Query Charts with new selection features and zoom
capabilities
Upgraded Calculation interface with easier user ability
New eRIS support forum with embedded access in eRIS
14-17 Manual Booster Operation on
Station Re-start Checklist
The ‘Manual Booster Operation Re-start Checklist’ was created to cover all the
compliance procedures and necessary documentation required to bring a Facility
back on-line after the following:
1. Post Auto Low Chlorine Shutdown Condition.
2. Facility off-line resulting in non-representative values @ Analyzer
14-18 Water Meter Testing Pilot Installed a meter testing station at Water Services for a demonstration project
that the metering group is developing.
14-19 Expansion of the Rainwater
Harvesting Rebate Program
The Rainwater Harvesting Rebate Program now offers two different rebates:
1) Seasonal outdoor system: Install an approved rainwater harvesting
seasonal tank and receive a one–time rebate of $0.10/litre of tank storage
(to a maximum of $400); or
2) All–season indoor/outdoor system: Install an approved all–season
rainwater harvesting system and receive a $2,000 rebate.
14-20 Improved process for Operator
comments regarding alarms
The SCADA Operator now completes the twice daily eRIS Facility Trend
Reviews; and alarm comments can be limited to “reportable” or “non-
reportable” with an indication as to where more information can be found.
14-21 Increased Emma’s VOC
Sampling Schedule to Quarterly
In response to Emma reaching ½ MAC (half of maximum allowable
concentration) for VOC’s, the related sampling schedule has been increased to
quarterly.
14-22
Updated Supply Processes using
manufacturer instructions to
include new MDWL UV
requirements.
Updated Supply Processes using manufacturer instructions, to include new
requirement in the Municipal Drinking Water Licence (MDWL) related to tracking
UV lamp hours so that “…continuous pass-through UV dose is maintained
throughout the lifetime of the UV lamps…” Trojan recommends UV sensor
verification on a monthly basis and re-calibration of the reference sensor every
Annual and Summary Report
Page 51 of 77
OFI # Suggestion Title Improvement Action Description
three years (however, more stringent requirement of annually is required by the
MDWL).
14-23 New Security System at all
Water Services Sites
New security system is implemented to keep buildings, equipment and water
supply and treatment system safe. By-law will be able to monitor the cameras
remotely 24/7 as they already do for many other satellite sites throughout the
City to help keep us secure and aware of intruders. Certain staff will also be
able to monitor our cameras from here ourselves. Camera recording usage and
data retention time will remain consistent with City policy.
14-24 Arkell Well Houses Inspected
and Repaired for Safety Issues
Found snakes’ points of entry at Arkell Well Houses (e.g. #1, #6, #15) and
repaired (filled with foam) to prevent re-entry.
14-25 Chemical-resistant (e.g. Viton)
gaskets, o-rings, etc. installed
Outlet four-bolt flanges plumbed in sodium hypochlorite storage tanks leaked
when the gaskets (that were evidently not chemical-resistant) broke down. The
leaking gaskets were replaced with a chemical resistant product (e.g. Viton) to
prevent future leaks. Future replacements of gaskets and o-rings will be of a
chemical-resistant nature (e.g. Viton) when they’re interacting with chemicals.
14-26
Numbered fire extinguishers to
better track monthly fire
extinguisher inspections
All fire extinguishers now have a numbered identifier. Floor plans are updated
with the location of each numbered extinguisher. The information is also
organized with extinguisher numbers by building location to facilitate inspection.
14-27 Paisley monitoring screen
updates
Paisley screen updated to show inlet valves Local/Remote status on the main
screen. Also cleaned up some font sizes.
14-28
Zone 2 closed pressure system
tested & work instructions
developed
Tested new equipment and programming associated with the ‘Zone 2 Closed
Pressure System’. The two testing periods (one evening and one weekend)
confirmed that Zone 2 could be successfully run as a closed pressure system.
14-29 Verney Tower cable restraint
system inspection
Unistrut performed the inspection of the cable restraint system at Verney
Tower.

Appendix “C” – Total Water Pumped and Instantaneous Flows
Note on Capacity:
Capacity is calculated by comparing the average pumped or flow value against the MDWL allowable
volume or PTTW flow. Capacity is representative of the conditions of pumping for that year which may be
influenced by other testing programs, maintenance or special operational conditions. Additionally, the
actual capacity of the source may not be achievable with current infrastructure. Optimization efforts are
included as a component of the Water Supply Master Plan with the intent to match the actual capacity of
the water source with the appropriate infrastructure.

Appendix “D” – Water Conservation & Efficiency Program – 2014 Annual
Progress Report (updated annually)
Background:
The City of Guelph strives to be a leader in water conservation and efficiency. As one of Canada’s largest
communities reliant on a finite groundwater source, our ability to reclaim precious water capacity through
conservation initiatives offers numerous benefits to our community and local ecosystem.
In 2006 City Council endorsed the Water Supply Master Plan (WSMP). This detailed Master Plan evaluated
the water demand associated with projected growth over a 50 year planning horizon, as well as alternative
sources of new water supply. Water conservation was identified as the most cost-effective and
immediately available source of new water supply and was ranked as the top priority. The WSMP included
three reduction targets based on 2006 daily water production volumes:
Reduction of 10 per cent (5,300 m3/day) in average day water use by 2010;
Reduction of 15 per cent (7,950 m3/day) in average day water use by 2017; and
Reduction of 20 per cent (10,600 m3/day) in average day water use by 2025
Both the 2007 Community Energy Initiative and the 2007 Council Strategic Plan set sustainability
performance goals of using “less water and energy per capita than any comparable Canadian city.” These
goals continue to guide our current water conservation activities and bring greater emphasis to the
relationship between water supply and energy demand.
To achieve these targets, staff initiated the Water Conservation and Efficiency Strategy (WCES) Update in
February of 2008. This award winning, 10-year strategy was endorsed by Council in May 2009 and
identifies the preferred program, policy and resource recommendations to achieve a further reduction of
8,773 m3/day by 2019, as well as to achieve the aggressive reduction targets of the Water Supply Master
Plan, Water and Wastewater Master Servicing Study, Wastewater Treatment Master Plan, Community
Energy Initiative, and Council's Strategic Plan.
Since Council’s approval of the 2006 Water Supply Master Plan, 7,116 m3/day of average day
water/wastewater capacity has been reclaimed as a result of the City’s Water Conservation Program,
allowing the City to delay the need for close to $35.6 million in additional water and wastewater
infrastructure with an investment of approximately $8.6 million in water conservation programming.
In addition, since 2001 when the City’s Outside Water Use Program was first implemented, the community
has reduced our annual peak day water use (i.e. the highest daily demand for water each year) by over
21,200 m3/day, thus reducing infrastructure required to meet peak demand which is experienced on only
a few days each year.
Furthermore, water conservation has led to a reduction in the amount of electricity and water treatment
chemicals used to treat and convey water and wastewater. This results in an annual operational savings of
over $470,000 per year, creating a significant financial benefit to our rate payers. As a result of such
efforts, the City’s water and wastewater rates remain much lower (within the 50th percentile) than that of
many comparable Ontario and local municipalities.

2014 Progress Overview
The following sections provide an overview of Water Conservation and Efficiency Program activities
undertaken in 2014. For more information on individual programs or initiatives please visit:
guelph.ca/ourstoconserve.
1. Leak Detection Program
The City’s leak detection program aims to reduce the amount of water lost between the time of
production and end delivery to customers. In 2014 the program included the evaluation of 287 km
of the City’s linear watermain infrastructure through use of sounding and correlation technologies.
In total 3 watermain breaks of significance and number of distribution maintenance
recommendations were identified through the study with approximately 1024 m3/day in water
production capacity anticipated to be reclaimed as a result of remediation of watermain breaks
discovered.
The 2014 Leak Detection Program also included the continued introduction of district metered areas
(DMA) within six separate locations of the Guelph water distribution system as well as ongoing
monitoring of the City’s first DMA in the Woodland Glen neighbourhood on Stone Rd West. Through
employment of this industry best practice for water loss management, a permanent underground
flow meter(s) and chamber(s) are installed in parallel with isolation of an area of the water
distribution system to allow water use in this area to be monitored through a single or multiple
metered watermain feed, on a continuous basis. This approach to water loss mitigation will allow
staff to define the normal profile of efficient water delivery for defined areas of the water
distribution system and provide a baseline to evaluate future demands against, so to assess the
occurrence of potential leakage within the area. As an innovative feature of the City’s field
implementation of DMAs, field information from each flow meter will be transmitted via cellular
network to the City’s SCADA system where information will be logged and flows assessed versus
established control limits to define the occurrence of previously unknown leaks in areas of the
distribution system. This approach to water loss management is anticipated to allow for the
proactive response to distribution system leaks and support the retention of water savings already
reclaimed from prior leakage restoration.
Resources for implementation of DMAs in 2014, and associated water and energy distribution
optimization activities, were graciously provided by the Province of Ontario’s Showcasing Water
Innovation Program. In recognition of benefits offered through this proactive water loss
management approach, Guelph Water Services will be working to implement an additional 21 DMAs
over the period of 2015 to 2018 with funding provided through local development charges and local
user rates, with the intent of reclaiming 1.5 MLD (approximately 3.3 per cent on 2015 daily system
input volume) in water servicing capacity by 2019.
2. Residential Water Conservation Rebate Programs
During 2014, a total number of 2,086 rebate applications were processed via the City’s residential
rebate programs. The majority of rebates claimed continue to be based in the City’s Royal Flush
Toilet Rebate and Smart Wash Clothes Washer Rebate Programs, with a limited amount through
Annual and Summary Report
Page 68 of 77
the Home Humidifier Rebate Program. In total, approximately 230 m3/day of reclaimed water
savings is anticipated as a result of residential rebate program participation in 2014.
Further to routine promotion of the City’s water conservation retrofit programs, Water Services also
initiated customized engagement of the local business sectors in 2014 to increase awareness of
program resources and potential water use efficiencies specific to the sector. This included a multi-
residential marketing campaign for building owners comparing individual building unit water
consumption to multi–residential sector averages, as well as anticipated utility savings and return
on investment for buildings pursuing mass retrofit of inefficient toilets. Staff also initiated an
engagement campaign of local restaurants promoting efficiency opportunities to reduce operational
costs while enhancing the experience of patrons. Staff plan to further build upon these engagement
campaigns in 2015 as well as seek other ways to customize engagement to defined sectors
possessing water saving opportunities.
For more information on the City’s Water Conservation Rebate Programs please visit
guelph.ca/rebates.
3. Institutional, Commercial and Industrial (ICI) Water Capacity Buyback Program
Since introduction of the ICI Water Capacity Buyback Program in 2007, the City has reclaimed over
1,500 m3 per day in water/wastewater servicing capacity, while assisting local business to reduce
their environmental footprint and ongoing operational costs. This program offers financial
assistance to local business for the completion of detailed water efficiency process audits and
incentives towards capital retrofits which reduce water demand.
From 2007 through 2010, several of the City’s top water users had participated in this program,
but participation amongst business possessing a smaller water use footprint had been limited due
to investment required to undertake process audits and uncertainties of financial efficiencies to be
realized as result of participation. In recognition of these challenges, Water Services’ ICI Water
Efficiency Specialist continued work in 2014 to engage and support all members of the Guelph
business community. This resource offers the local business community engineering services in
conducting detailed preliminary water use audits with the intent of realizing potential efficiencies
and limiting financial risk to business due to program participation.
Through this program resource, five detailed facility audits were completed in 2014. Furthermore,
2014 also saw the benefit of relationships built through the tenure of the program with local
businesses returning to the program to seek support to implement further site–based efficiencies
and inform process decisions. This included water efficiency capital retrofits implemented by the
University of Guelph and Blount Canada accounting for a total of 227 m3/day in observed water use
reduction.
4. Civic Facility Water Efficiency Upgrades
With the objective of leading by example through the City’s own operations, work in support of City
operational improvements continued throughout 2014.
Most notably, construction of a rainwater harvesting system to supplement the final wash phase of
Guelph Transit’s Bus Wash was completed on October 8, 2014. Since implementation,
Annual and Summary Report
Page 69 of 77
approximately 110 m3 of City water has been offset with rainwater, and installation of high-
efficiency nozzles has decreased bus wash water consumption by an estimated 456 m3/year. By
offset of this final wash phase, it is hoped that wash water and chemical use can be reduced by 40
per cent – a savings of approximately $7,000 per year to the Transit Utility. This project was made
possible thanks to funding provided by the Province of Ontario’s Showcasing Water Innovation
Program.
Further to the above, detailed water use audits of sixteen of the City’s highest water-using facilities
were initiated in 2014 as part of preliminary works for update of the City’s 2009 Water
Conservation and Efficiency Strategy. These works and small scale facility technology efficiency
trials are currently ongoing at this time with a report summarizing findings and estimated potential
savings anticipated for release in Q2 2015.
5. eMERGE Home Visit and Audit Service Program Update
eMERGE Guelph is an innovative collaboration between the City of Guelph, Guelph Hydro Electric
Systems Inc., Union Gas, Transition Guelph, Elora Environment Centre, and other local partners.
Building on the success of the Efficient Home Visit pilot program that ended in March 2012, the
eMERGE–led home visit service has expanded into a unique collaboration to help homeowners
achieve energy, water and waste reductions while enhancing transportation and food choices, and
inspiring green renovations in and around the home. The focus is on empowering citizens,
connecting neighbourhoods and transforming community toward a net zero environmental impact
in energy, carbon, water and waste.
The eMERGE Guelph Efficient Home Visit service continued with great success in 2014. This service
offers a free 45–minute home audit by trained advisors, a complimentary retrofit of common home
water use fixtures (such as water efficient showerheads and faucet aerators), and the development
of a household–specific action plan, providing information to residents on how to further reduce
home resource use and directing homeowners to further resources and tools to assist with the
implementation of recommended improvements.
This program, recommended through the Council approved 2009 Water Conservation and Efficiency
Strategy, is available to all residential households in the City of Guelph with utility servicing from
Guelph Hydro Electric System Inc., Union Gas and the City; the program has a base goal of
completing 900 home audits by December 31, 2015. For more information please visit
emergeguelph.ca.
6. Blue Built Home Water Efficiency Standards and Rebate Program
Endorsed by City Council in November 2010, the Blue Built Home Water Efficiency Standards and
Rebate Program is a voluntary construction standard designed to outperform the plumbing and
water–using fixture requirements of the Ontario Building Code. This certification program for new
homes uses an approved set of high-quality home fixtures and appliances designed and third-party
tested to save water and reduce water and wastewater utility bills by 15 to 62 per cent. Blue Built
Homes are certified according to three water efficiency standards—Bronze, Silver or Gold—and
provide home buyers with a one-time rebate on their investment.
Annual and Summary Report
Page 70 of 77
Since launch of the program, a total of 29 new homes have been certified (27 Bronze, two Silver).
Of these, one Blue Built Bronze home, constructed by Habitat for Humanity was certified in year,
with construction of additional 22 Blue Built Homes initiating by TerraView Homes in mid-2014.
To evaluate the impact of this building standard, water use datalogging at each Blue Built Home
took place through the use of radio–read flexible axis water meters. This data logging wrapped up
in May of 2013, after the majority of the homes were monitored for one full year. The evaluation of
water use in Blue Built Home Bronze homes, completed in 2014, has demonstrated an average
savings of 33.56 m3/year for a family of three persons compared to a standard home built
according to the 1996 Ontario Building Code (191.2 m3/year).
In 2014 work began to incorporate the Blue Built Home program into Planning Services processes.
In September 2014 planners began informing builders and developers of the program during their
pre-consultation meetings. Steps are being taken to incorporate the Blue Built Home program into
the Planning group’s pre-consultation document, and Sustainability Check-list.

7. Youth Education
The City’s curriculum based, Grade 2 and Grade 8 in–class water conservation programming
continues to be a popular resource for local educators in both the Upper Grand District School
Board (UGDSB) and the Wellington Catholic District School Board (WCDSB), encompassing 52
interactive school presentations to 2,512 students conducted in 2014. Overall since the inception of
this water conservation educational initiative four years ago, the City has provided a total of 214
school presentations to over 7,000 students.
Furthermore, in partnership with the Grand River Conservation Authority’s Guelph Lake Nature
Centre, a total of 758 local Grades 7, 8 and high school students, as well as volunteers,
participated in guided educational tours of the City’s Water Services facility in 2014. These
interactive tours lead students through the processes involved in supplying, treating, and
distributing the City’s drinking water, as well as educating participants about the importance of
water conservation and source water protection as an essential part of ensuring the sustainability
of our City’s water resources.
Beyond City–led programming, Water Services is proud to be an ongoing partner, sponsor and
contributor to the Waterloo Wellington Children’s Groundwater Festival. This long–standing festival
celebrated its 19th year 2014. The Festival annually educates more than 4,000 grade two through
five Guelph, Wellington County and Region of Waterloo students. Since 1996, over 80,000 students
have participated in the Festival which features fun and interactive activities designed to inform
students of the importance of water protection and conservation in their daily lives. In partnership
with the Upper Grand District and Wellington Catholic School Boards, staff have worked to increase
local awareness and participation in this Festival with upwards of 800 Guelph–based students now
participating in the event on an annual basis.

8. Canada Water Week
Canada Water Week, a national, week-long celebration of water, is held annually during the third
week of March to coincide with World Water Day on March 22. In 2014, Canada Water Week was
held March 16th to 22nd with the theme: “Watersheds 101.”
2014 marked the City’s third year of participation in Canada Water Week programming with a
number of activities offered locally including a speaker’s event, March’s Water Wednesdays family
education programming at a variety of library locations throughout the City, a school art project,
and the second H2O Go! Festival at City Hall. The second annual H2O Go! Festival, a one-day event
to celebrate water, attracted over 400 participants again this year. In total, this successful event
featured workshops, information sessions, community booths, performances by local artists and
interactive children’s activities celebrating the protection, conservation and stewardship of our
precious water resources.

9. Peak Season Water Demand Management
Reduction of peak season water demands continue to be a primary objective of the City’s Water
Conservation programming. The ability to reduce variations in seasonal water use limits impacts on
our finite groundwater supply during times of environmental stress and creates operational
efficiencies by reducing capital and operational investment to service our community for only a few
days a year. Since 2002, the City’s Outside Water Use Program has helped to manage peak season
water use via regulatory controls with complementary programs, such as Healthy Landscapes,
working to proactively manage potential peak demands by assisting residents and local businesses
in establishing low outdoor water use environments.
Following 2013, a season of above average precipitation and consistent river levels within the
watershed, the City’s Outside Water Use Program remained at Level 0 Blue throughout 2014 due
significant seasonal precipitation, low temperatures, stable water flows throughout the watershed,
and overall community compliance with program terms.
In response to stakeholder concerns received through implementation of Level 2 Red water use
restrictions during the prolonged drought periods of 2012, Water Services initiated a review of the
Outside Water By-law in January 2013. This multi-phase project, designed in accordance with the
City’s Community Engagement Framework, engaged residents and local stakeholders in an
interactive dialogue on potential changes to the program and by-law. In concert with this public by-
law review process, staff also initiated an internal, multi-departmental Municipal Drought Response
Working Group to evaluate corporate peak season water use and to define protocols for response of
municipal operations during low water conditions.
In February 2014 Guelph City Council approved the revised Outside Water Use By-law. The revised
By-law and associated program changes came into effect on April 1, 2014. Following the
implementation of the revised By-law, new road sign info graphics were created, emphasizing the
permissions and restrictions for the most common outside water uses during the current program
level: lawn, garden and tree watering, and at–home car washing. Furthermore, based on
recommendations of the review, staff had worked to amend the City’s Rainwater Harvesting Rebate
Annual and Summary Report
Page 72 of 77
Program to create an individual program stream for seasonal rainwater harvesting systems, which
was launched to the public on May 1, 2015. More information on this new program resource can be
found at www.guelph.ca/rainwater.
In working to proactively manage peak season demand, the Healthy Landscapes Program offered
various public resources throughout 2014. The annual Healthy Landscapes Workshop/Seminar
Series featured numerous free talks on time–of–year appropriate outdoor water conservation topics
including water efficient landscape design, plant selection, and proactive maintenance best
practices to manage the impact of drought and common turf pests.
In addition, a Water Services’ Open House, rain barrel truckload sale, and plant sale was organized
in May of 2014 with over 500 rain barrels sold as part of the one day event. Rain barrels offer
homeowners the benefit of capturing free volumes of water for outside use but also assist in
managing stormwater impacts on private property. The sale of rain barrels are a net zero service to
the City as the barrels are sold at the bulk rate attained through an annual rain barrel tender
process.
Further to the above, the Healthy Landscapes assessment program continues to be a popular
resource with 252 visits completed in 2014. This service offers a complementary site–based
consultation aiming to educate residents on garden design and maintenance practices to
significantly curb outdoor demand at their home. Water efficiency studies completed in other
Ontario communities have shown a net result of 74 litres per day per household during peak
season as a result of similar water efficiency–based landscape consultant services.
For more information on the Healthy Landscapes Program please visit guelph.ca/healthylandscapes.
10. Water Conservation Web Portal
In alignment with open government objectives of Council’s 2012 Strategic Plan, Water Services
initiated discussions in early 2014 with the University of Guelph Research Shop regarding
opportunities to increase customer accessibility to personal water use data and create associated
engagement platforms to direct customer conservation opportunities based on known customer
attributes. Based on the these discussions, a project was initiated with the University of Guelph
School of Computer Science to develop a Water Conservation Web Portal which would draw upon
personal household consumption information, following account holder approval, to form
customized customer engagement reporting and links to supporting City resources as merited by
household resource utilization and other data inputs provided by the customer. Development of this
tool is currently ongoing at this time with release tentatively scheduled for late 2015.
11. Template Assisted Crystallization Performance Study
With high levels of naturally occurring hardness in the City’s groundwater source, the use of
residential ion exchange water softener technologies is quite common amongst Guelph households,
measured to be present in approximately 77 per cent of local households as part of a 2009
residential call survey. With significant annual water use and wastewater stream salt loadings
associated with the ongoing operation of these systems, Guelph Water Services in partnership with
the Region of Waterloo continue to research ion exchange technology improvements and non-ion
Annual and Summary Report
Page 73 of 77
exchange technology alternatives in support regional Source Water Protection commitments and
respective local water demand reduction targets.
A recent study commissioned by the US WaterReuse Research Foundation (WRRF) evaluating
alternatives to domestic ion-exchange water softeners identified viable potential in the template
assisted crystallization or TAC as an alternative to ion exchange water softening. This relatively
new technology converts calcium and magnesium (hardness) into microscopic crystals that will stay
suspended in water without forming scale on pipes and appliances. The TAC unit, certified by The
German Technical Association for Gas and Water (DVGW), reduced scale by over 90 per cent
during the WRRF study, which is comparable to ion exchange water softening. Unlike ion exchange
softeners, the TAC units require no water for backwash, and no salt.
With limited availability and uptake within the Canadian marketplace to date, the Region and City
initiated a multi-phased study in 2014 to better understand the extent of practice, appropriateness
and limitations of TAC so to inform future community education and related programming. Study
activities in 2014 included completion of a detailed TAC market assessment, engagement of early
adopters of the TAC technology and development of a performance testing protocol in consultation
with industry experts and stakeholders. As part of the next phase of the project it is planned that
field testing of a number of TAC technologies will be performed in a controlled environment to
assess performance of these technologies versus the severe hard water sources seen locally.
Following completion of the testing and analysis of results attained, it is planned that a final report
for the study will be released in late 2015/early 2016 for public reference.
Water Reduction Target Progress
In 2006 City Council endorsed the Water Supply Master Plan (WSMP). This detailed Master Plan evaluated
the water demand associated with projected growth over a 50 year planning horizon, as well as alternative
sources of new water supply. Water conservation was identified as the most cost-effective and
immediately available source of new water supply and was ranked as the number one priority. The WSMP
included three reduction targets based on 2006 daily water production volumes:
Reduction of 10 per cent (5,300 m3/day) in average day water use by 2010;
Reduction of 15 per cent (7,950 m3/day) in average day water use by 2017; and
Reduction of 20 per cent (10,600 m3/day) in average day water use by 2025
As of December 31, 2013, annual average day water production has decreased by 5,923 m3/day (14 per
cent) since 2006, with an estimated direct savings of 7,116 m3/day attributed to community participation
in the City’s Water Conservation Programs. This observed reduction to date places the City in a
competitive position to reach its 2017 water reduction target. Further to the information above, Figure 7
below shares estimated water savings to date versus the annual conservation program reduction targets
of the City’s 2009 Water Conservation Strategy:
Annual and Summary Report
Page 74 of 77
Figure 7: Water Conservation and Efficiency Strategy Update:
Estimated Annual Savings vs. Program Reduction Targets
In July of 2014 Guelph City Council endorsed the Water Supply Master Plan Update. Through update of
this Master Plan, water capacity reclaimed through Water Conservation and Efficiency continued to be a
top priority in achieving a sustainable and cost effective community water supply. Through the evaluation
of the feasibility and value of multiple Water Conservation Program Scenarios the final Master Plan
recommended the City’s demand reduction target be revised to achieve an addition 9,150m3 per average
day of supply capacity by 2038, the planning period of the City’s Official Plan. With reference to this new
time based goal guiding the City’s Water Efficiency Program, it is now necessary that Guelph Water
Services revise its 2009 Water Conservation and Efficiency Strategy to identify preferred program
resources for the next planning period of 2016 to 2020. Update of this strategy will initiate in January of
2015 with further information on this strategy and opportunities for public involvement to be made
available at www.guelph.ca/ourstoconserve.
