OVERVIEW

This report is for Water Services activities for December 2017 and January 2018. Significant items in this period include:

No Lost Time Injuries occurred in December 2017 or January 2018

Round One of the $11.49M Works for Queensland State Government funded job creating and

supporting initiative was completed. The following projects were completed:

o A water main replacement along Smalleys Beach Road, Cape Hillsborough and

geobag protection works to the Campwin Beach Water Supply Main by the Water

Networks Team;

o Sarina Sewerage System cleaning, CCTV inspections and rehabilitation works by the

Sewer Networks Team with upgrades of two sewer overflows coordinated through

Planning & Sustainability;

o Redrilling and equipping of two bores, renewal of pumps and sheds for the other five

bores supplying the Nebo Road Water Treatment Plant and installation of an

educational display on the clarifier structures by the Water Treatment and Business

Services Teams;

Under bridge inspections of Water & Sewer Mains were completed on both Forgan Bridge and

Barnes Creek Bridge in January 2018

A condition assessment on the clarifier tanks was completed at the Nebo Road Water

Treatment Plant in January 2018. The work was completed with no incidents, no issues, whilst

ensuring steady and quality water supply to the region

As of Sunday, 28 January 2018, recycled water supplies at Recycled Water Storage 3, the main

2,200ML storage system within Mackay Water Recycling Project, were low. The pump station

was turned off and will remain off until supply has been replenished. Recycled Water Storage

2, the secondary 530ML storage system, is currently at 40% capacity. These storage systems

are used to distribute recycled water to sugar cane properties within the project area. Growers

have taken up approximately 3,100ML, or almost 40% of recycled water produced for the

Scheme since 1 July 2017.

3.6. Building Over Adjacent Sewers

Building over adjacent sewer (BOAS) applications are lodged where the construction of a structure is proposed within close proximity of a sewer main. The application is assessed against Queensland Development Code Mandatory Part 1.4 with council reviewing applications that do not comply with acceptable solutions identified in the code. Building over sewer applications are assessed within a target timeframe of 20 business days.


Three new BOAS referrals were received in December 2017 and none in January 2018. Plumbing Inspectors continue to handle enquiries and provide information on infrastructure locations and general information regarding the Queensland Development Code.

3.7. Scientific and Analytical Services

Scientific and Analytical Services provides laboratory analysis in accordance with National Association of Testing Authorities (NATA) Standards to both Mackay Regional Council and external customers. A summary of the laboratory activities is detailed below.


The number of sample batches registered and the number of samples tested fell in December 2017. During December 2017, several tests were completed for Whitsunday Regional Council; i.e. Bowen Sewerage characterisation. The number of sample batches registered, samples tested and tests performed increased significantly in January 2018. During January 2018, most the quarterly requirements for potable water (Mackay Regional Council and Isaac Regional Council) were performed. Overall, more than 29,000 tests were performed during January 2018.

The average leak days shows the average number of days a leak exists before any action is taken by the customer to rectify. The average leak days for ceased leaks shows the average number of days that the leak exists before being repaired.


The Average Leak Days (current leaks) for both residential and non-residential customers decreased during January 2018. The difference between non-residential and residential for current leak days is 132 days. The Average Leak Days (Ceased Leaks) show that the residential customer has the leaks repaired within 14 days on average, whereas the non-residential customer takes 31 days to have leaks repaired on average. Considerable effort is undertaken with non-residential customers to encourage attention to fix the identified leaks, however, some of these leaks are very difficult to track down due to the size and complexity of their property.

ASSET MANAGEMENT 4.1. Surface Water Raw Water Storage Capacities

Water is sourced from a combination of surface and groundwater sources. With the exception of Middle Creek Dam, the storage facilities are owned and operated by SunWater. Middle Creek Dam is under Council’s control. The water stored in each of the storages is detailed below.


Marian and Dumbleton Weirs are at full capacity. Mirani Weir, Teemburra Dam and Peter Faust Dam are at 88%, 88% and 70% capacity respectively which is a decrease in capacity from the previous month. Middle Creek Dam is at 45% capacity.

4.2. Annual Water Consumption vs Allocation by Source

Water Services has an annual water allocation or water license for each water source. The water allocation and year to date water consumption for each of the water source is detailed below.

** Calen Water Usage figures are not based on Water Allocation, but show the amount of water usage for the area to date.

4.3. Water Consumption by Locality – Residential Customers Only

Water Services supplies potable water to both residential and commercial customers throughout the Mackay region. The average water consumption in each of the three major community centres is detailed below for residential customers only. The water consumption is presented as litres per equivalent population per day (l/p/d).


Water consumption for all three major community centres has increased over December 2017 and January 2018 due to the minimal rainfall in the region. When there is rainfall, the three centres of Mackay, Sarina and Marian/Mirani generally show similar water consumption. It is only when there is no rainfall that Marian/Mirani consumption increases above Mackay and Sarina.

Sewerage Network Refurbishments (Relining)

Proc 80% Schedule Scheduled Completion Date:

30/06/2018

Original Budget:

$2,525,260

The project includes 17km of sewer inspection and condition assessment using CCTV and the internal relining repair of 8.4 km of sewer in the size range 150 to 900mm diameter. A number of Tender Information Requests have been issued in September and October to address incomplete Tender responses and facilitate parity. Based on the responses received, a potential issue with availability of Contractors impacting the timing of the works has resulted in an advice to Tenderers to program resources to commence relining works in April 2018 - outside of the critical wet weather period when sewers are more accessible. Associated with this change, most expenditure is being forecast into 18/19.

The Principal has re-visited the Technology offerings in terms of risk mitigation during construction and further clarifications have been issued together with an extension to validity period. Tender evaluation is expected to be completed in February 2018.

Drilling of an investigation bore commenced in November 2017. It was confirmed that there were two aquifers, though a complication was identified during drilling leading to potential cross contamination between the two aquifers. Technical resolution required that the existing investigation bore be supplemented by the drilling of a second trial bore in the shallower aquifer, completed in December 2017. Better water quality results have been recorded on the shallow trial bore so drilling the final production bore located in the shallower aquifer is scheduled to commence late January 2017. Hydraulic Modelling work is complete. Specifications are prepared for the water softening equipment and civil works.

Recent analysis of Eton water samples indicated that pH correction is also required to stabilise the water quality in the networks. As a consequence, additional concept design work and Technical Specifications are required for pH correction equipment to be installed under the contract works. This additional scope will impact the budget with the quantum to be established once the process concept design and specifications are established.

Council's consultant is working on a revised specification. Once the pH correction specification is complete and the contract conditions and schedules are finalised, a tender will be released and this is now expected by end of February 2018.

REGULATORY COMPLIANCE 5.1. Drinking Water Compliance

Potable water is provided in accordance with the requirements of the Water Supply Safety and Reliability Act, measured against the Australian Drinking Water Quality Guidelines. Drinking Water samples are taken at the outlet of Water Treatment Plants and at various locations within the reticulation network. Please note: These results are reported one month in arrears. A summary of the performance is detailed below.

December 2017 Summary:

Eton reticulation samples for Selenium continue to be in the range of 10-12 ug/L. pH was detected to be below the Australian Drinking Water Quality Aesthetic Guideline Value of 6.5 recommended limit at Gargett, being 6.37 on one occasion.

December 2017 Summary:

Eton continues to have high values for the aesthetic parameter of hardness (>200 mg/l), with values ranging from 370 mg/l to 405 mg/l respectively. These hardness levels will be addressed in the future with the planned provision of water softening plants as part of the Scheme.

5.2. Wastewater Compliance

The discharges from wastewater treatment facilities are regulated by Development Approvals issued by the Department of Environment and Heritage Protection. The licence requirements differ based on the year the Development Approval was issued and the receiving environment associated with discharges.


Three wastewater tests were non-compliant in December 2017. These related to a breach of suspended solids for Recycled Water Storage 2 releases to water due to algal growth; pH for Nebo Road WTP supernatant released to water; and total phosphorus for Sarina Water Recycled Facility permeate released to environmental waters. One wastewater test was non-compliant in January 2018. This relates to non-compliance for faecal coliforms at Seaforth Wastewater Treatment Plant. The Regulator was informed of each occurrence within appropriate timeframes.

5.3. Backflow Testing

Backflow devices are installed on water services where there is a risk that water could return from a private property back into the Water Reticulation network. The requirement for backflow devices is regulated in accordance with the Standard Plumbing and Drainage Regulation.


13 new devices were registered, while 10 devices were cancelled in December 2017. 19 new devices were registered, while 12 devices were cancelled in January 2018. Council performed 55 tests on backflow devices in December 2017 and 45 tests on backflow devices in January 2018.
