1 General
1.1 Objective of the Project
The Transit Joint Powers Authority (TJPA) is currently developing plans to
significantly decrease the use of potable water for non-potable uses with
its comprehensive approach to the use of alternate water sources such as
rainwater and graywater at the Transbay Transit Center (TTC).
TTC encompasses a large scale integrated water management system.
Graywater is collected from restroom sinks, not including restroom sinks
from the Tenant Retail Space and conveyed to a treatment and
storage system.
Rainwater runoff is collected from the rooftop park and then piped to
the storage system after pre-treatment.
Blackwater (from toilets, urinals, service sinks, etc.) is directed to the
city’s sewer system.
Water treatment happens at different stages throughout the system by
means of physical, biological and mechanical processes. This
combination of processes is typically necessary for water reuse.
At the rooftop park a subsurface constructed wetland performs
polishing treatment of graywater. No water is exposed at the surface
of the wetland nor is any human contact with untreated graywater
allowed. The subsurface constructed wetland, also called the Water
Reuse Garden presents a unique opportunity for public education and
engagement while creating a rich and diverse habitat island within
the dense urban landscape.
At the end of conveyance, storage, filtering and treatment processes,
the graywater will be reused for toilet flushing for the Transbay Transit
Center, including the Tenant Retail Space.
1.2 Facility Information
The Transbay Program is a $4.5 billion project to replace the former
Transbay Terminal at First and Mission streets in San Francisco with a
modern regional transit hub that will connect eight Bay Area counties and
the State of California through eleven transit systems: Alameda–Contra
Costa Transit, BART (Bay Area Rapid Transit), Caltrain, Golden Gate Transit,
Greyhound, Muni (San Francisco municipal bus lines), SamTrans (San
Mateo County Transit), WestCAT (Western Contra Costa Transit) Lynx,
Amtrak, Paratransit, and high-speed rail from San Francisco to Los
Angeles/Anaheim.
The Transbay Program will be constructed in two phases. Phase 1 includes
design and construction of the above-grade portion of the Transit Center
which is located between Second Street and Beale Street and between
Minna Street and Natoma Street. The structure and core of the two

below-grade levels of the train station, new bus ramps, a bus storage
facility, and a temporary bus terminal. The Downtown Rail Extension (DTX)
tunnel, the build-out of the below-grade train station facilities at the Transit
Center, a pedestrian tunnel, and an intercity bus facility will follow as
Phase 2 of the Program.
The TTC will feature “City Park,” a public 5.4-acre rooftop park. The 1,400
foot long elevated park will feature a wide range of activities and
amenities, including an outdoor amphitheater, gardens, trails, open grass
areas, and children’s play space, as well as a restaurant and café.
Highlights of City Park include:
Green roof with sustainable design features
Public space including both quiet and active areas
Restaurant and cafe
Open air amphitheater
Display gardens featuring climate-appropriate plants
Children’s play spaces
Pedestrian bridges connecting surround development to the park
Bike storage to accommodate approximately 600 bikes
Ten different public access points
2 Rules and Regulations
2.1 San Francisco Department of Public Health
Article 12C, Section 853 of the San Francisco Health Code established
permitting requirements for the use of alternate water sources for non-
potable applications and set permit and annual fees. The San Francisco
Department of Public Health (SFDPH) is responsible for ensuring that
Alternate Water Source Systems are in compliance with applicable laws.
SFDPH performs ongoing monitoring, review, and inspections of permitted
Alternate Water Source Systems to ensure such compliance is maintained.
As established in the City and County of San Francisco Charter section
4.110, the SFDPH is authorized to perform duties associated with regulating
the internal uses of recycled water through its general authority to provide
for the preservation, promotion and protection of the health of the
inhabitants of the City and County.
Additionally, Articles 11 and 12A of the City’s Health Code authorize the
SFDPH to investigate and abate any nuisance, activity, or condition that
the SFDPH deems to be a threat to public health and safety, and to
investigate and abate any cross connection risks between potable and
Non-Potable Water and sanitation systems in both public and private
facilities. The Health Code authorizes the SFDPH to order a person to
vacate property, cease prohibited activities, abate unsafe or unsanitary
conditions, and pay penalties for violations.

2.2 San Francisco Public Utilities Commission
The San Francisco Public Utilities Commission (SFPUC) would provide water
and wastewater services to the Transbay Program.
3 Producer-Distributer-User
The Contractor implicated in the system operation and maintenance has
not been chosen at this time, but the Contractor would have to have the
experience and the manpower to operate and maintain the system in
accordance to SFPDH requirements.
The Producer, Distributor and System Operator for this project are the
same agency, the TJPA.
Users of non-potable water generated by the system include TJPA
employee, the general public who visit the TTC and transit system
passengers.
4 Non-Potable Supply Sources, Flows, Water Quality and Characteristics
4.1 Non-Potable Supply Sources
Wastewater flows are segregated and piped separately as graywater
and blackwater. Blackwater from the toilets and urinals, air handlers and
any other sources are all discharged into the city sewer.
Graywater from showers and restroom sinks, not including restroom sinks
from the Tenant Retail Space, is collected for reuse. Also rainwater and
irrigation runoff is collected from the rooftop park landscape and
hardscape areas, also for building reuse. In the future other water sources
will likely become available such as municipally (SFPUC) supplied recycled
water. The municipally supplied potable/recycled water will be used to
supplement non-potable water needs.
4.2 Volumes and Flow Rates of the Non-Potable Sources

4.3 Source Water Quality Summary
The quality of graywater constantly fluctuates, thus it is difficult to
determine what the true composition of graywater at the TTC will be.
Many variables will cause fluctuations including: user inputs, time of year
and water temperature. Several studies analyzing the quality of
graywater have been compared to determine conservative values for
the quality of graywater.
It is anticipated that during the first few months after completion of the
roof park, rainwater runoff may contain a higher level than normal level of
turbidity because of soil on the park level. Typically after the first season
the runoff water quality will increase as the roof soil structure stabilizes.
The building usage will also change over time. The system is designed for
a maximum occupancy of the building, but graywater flows will be less
prior to Phase 2 of the program, which will include the extension of
Caltrain and the California High Speed Rail (CHSRA) of the TTC.
Water availability will vary significantly between the summer and winter
months. During the rainy season the graywater supply will be augmented
heavily by rainwater collection from the rooftop park. When CHSRA
service is at TTC, it is expected that during the summer months there will
be higher ridership and higher production of graywater. In any case,
when water supply is low potable water backup will supply water
necessary to meet the demand of the toilets and to provide a constant
supply of water to the wetland.

5 Treatment Process
5.1 Design Basis
Rainwater receives primary biological and physical treatment as it flows
through the roof park soil layer before draining into three storage tanks.
The rainwater will pass through a vortex filter before being stored. Once
rainwater is mixed with primary treated graywater in the storage tanks,
undergoes ozonation and chlorination, it assumes the designation of
treated graywater and is labeled as such.
Graywater requires primary mechanical treatment in the form of a pre-
screen filter, and a 25 micron basket filter. The pre-screen filter removes
large debris from the water and prevents clogging of plumbing, valves,
and pumps. Pumps located in the collection pit pressurize the water and
send it through the pre-screen filter and the 25 micron basket filter. The
graywater mechanical filtration system features a low flow backflush and
water quality monitoring system. The filter automatically cleans itself with
an efficient backflush, minimizing water loss.
For additional treatment, water on the eastern part of the facility
graywater is then pumped to the subsurface constructed wetlands on the
rooftop park for polishing treatment. Water is distributed evenly across the
width of the wetland cell by distribution piping. Gravity and hydrologic
pressure move the water through the wetland at a rate determined by
the projected graywater supply. Microbes in the filtration media and
wetland plant roots clean the water, removing nutrients and the
pathogens. In compliance with state codes, graywater will remain below
the surface at all times. Water flows through a layer of filtration media in
the subsurface wetland. A collection pipe at the opposite end of the
wetland receives the treated water. Water then flows through an
adjustable weir that gives the operator control of the water level in the
wetland. Finally a filter removes residual debris from the treated
graywater (wetland effluent) before being piped back to the concourse
level for ozone disinfection and storage.

Overflows to the sewer are provided throughout the system to prevent
building damage, ensure safety and to enable the maintenance of
various system components. For example, to accommodate for a storm
event greater than the holding capacity of the wetland, an overflow to
the sewer is provided.
5.2 Process Schematic
Rainwater runoff from the rooftop is directed through vortex filters, then to
three storage tanks. One tank contains rainwater only and two tanks
contain rainwater mixed with primary treated graywater. Graywater is
collected from sinks and showers in the bathrooms and is filtered through
one of two mechanical treatment systems located on the east and west
end of the TTC. Graywater on the west end is directed to the storage
tanks immediately after mechanical filtration, while graywater on the east
end of the facility is sent to the Park Level constructed wetland for
polishing before being collected in the storage tanks. Two 25,000 gallon
and one 50,000 gallon storage tanks hold water for reuse. Water is
transferred between the tanks to meet fluctuating demands across the
facility. Two of these are located on the lower concourse level and one
on the train platform level. An ozone sterilizer disinfects the water by
releasing ozone tanks into each tank. A small dose of chlorine is added to
ensure a 1ppm residual in the non-potable water, per IAPMO
recommendations.
The treated graywater from these tanks supplies all of the toilets and
urinals in the TTC. A back-up supply of domestic water ensures that a
minimum level of water remains in the tanks at all times. Domestic water is
used for make-up until the city supplied recycled water is available. There
is a capped connection to the future city provided recycled water in the
water pump room. When this source becomes available, new piping will
have to be installed to deliver make-up water to the capped connection
in lieu of the currently used potable water. New piping to connect to the
city provided recycled water will have to be installed regardless of
whether or not the water treatment system is included in the project. An
air gap is provided to ensure no cross contamination of the make-up
source.

5.3.15 Wetland System
1. Biological Water Treatment
Biological processes of plant roots, fungi, and bacteria filter water by
removing organic and inorganic pollutants. Biological water
treatment is successful when temperature, plant species, soil types,
nutrients, humidity, and the concentration of pollutants are all
considered.
2. Physical Water Treatment
Retention time in wetlands promotes physical treatment of graywater.
Contact with plant roots and growing media as well as the process of
sedimentation all contribute to the removal of pathogenic
microorganisms from the water column where they are metabolized
by the community of microorganisms within the soil.
3. Constructed Wetlands Overview
A constructed wetland is a bed, or series of beds or trenches filled with
substrate material and aquatic plants. This provides both aerobic and
anaerobic conditions. In sub-surface flow constructed wetlands water
is directed below the media surface, where treatment occurs.
Subsurface flow wetlands are the focus of this report to address any
concerns regarding public exposure to wastewater. The roots of plants
bring oxygen to the top eighteen inches of soil, but because
graywater will not be allowed to surface, mechanical pumps may be
needed to provide aeration.
Increased wetland efficiency is achieved through controlled flow
rates, engineered media, tailored plant lists, and wetland size and
shape. Constructed wetland projects are typically monitored and
documented, providing assurance that post-treatment water quality
meets the requirements of the EPA and other regulatory agencies.
4. Wetland Sizing
Wetland design and sizing is based on the methodology provided in
the Environmental Protection Agency (EPA) Manual, “Constructed
Wetlands Treatment of Municipal Wastewaters”. This manual provides
the federal guidelines for determining the capabilities of constructed
wetlands. Treatment objectives of constructed wetlands are to
achieve target levels for suspended solids, organic matter, pathogens
and nutrients. Target levels of treatment vary greatly depending on
regulatory agency regulations and expected end use of effluent
water.
Transbay Transit Center
Page 14
December 2014
The wetlands are designed to respond to the fluctuations in water
quality and flow rate. Since the occupancy of the TTC will be
constantly in flux the wetlands are designed to accommodate varying
flow rates. Residency time of the water in the wetlands can be
adjusted to accommodate variable flow rates. Wetlands will not have
to be irrigated with potable water when the occupancy is down;
instead, the residency time in the wetlands is increased to maintain a
minimal amount of water in the wetlands beds to maintain plant
health.
Figure 6 is a sectional view of the length of a wetland cell. Graywater
enters the inlet zone of the treatment wetland via a distribution
header.
BOD and TSS are removed through settling, flocculation and filtration
of suspended particles and large colloidal particles as the graywater
passes through the wetlands. The outlet is designed to allow the
operator to adjust the water level within the wetland through the use
of an in-line weir and to completely drain the wetland for
maintenance purposes, if necessary.
Wetland media consists of 18” depth of washed and graded +/- 5/16”
or +/- 3-4” expanded, kiln fired shale. The advantages of this material
are that is has a large amount of surface area, which aids in filtration,
and is very lightweight when compared to gravel or other media
types. Flow rate through wetland cells shall be at a constant rate of
~2.5 gpm per wetland cell.
5.4 Filtration and Disinfection Systems
5.4.1 Ozone Disinfection Technology
A variety of options are available for disinfection of graywater. Ozone is a
reliable and widely accepted means of disinfection and is the preferred
method for the TTC because it most effectively treats large volumes of
water quickly. It is not required to disinfect rainwater for toilet reuse, but
when the rainwater mixes with graywater both need to be treated with
ozone. Due to the high volumes and flow rates associated with rainwater,
a conventional chlorine system does not have adequate time to disinfect
the water without using large volumes of chlorine.
Collected rainwater and treated graywater is exposed to diffused ozone
bubbles. Ambient air generates the toxic gas that causes the cell wall of
an organism to burst, thereby destroying it.
Transbay Transit Center
Page 15
December 2014
The effectiveness of ozone disinfection depends on the characteristics of
wastewater, the intensity of ozone, the amount of time the
microorganisms are exposed to the ozone, and the dimensions of the
tank. The range of ozone concentration that will be maintained in the
tanks is 0.1 ppm to 0.5 ppm.
Ozone is produced on site, reducing the transportation and storage costs,
as well as the associated carbon footprint. With the proper design, the
only by-product of ozone disinfection is oxygen. There are three
components to an ozonation system: the generator, contactor, and
ozone destruction device. Ozone is produced in an ozone generator,
supplied with air and electricity. (USEPA 1999)
5.4.2 Ozone Generators
A high voltage (approximately 6,000 volts) is applied to two electrodes
and the high voltage produces an arc. In the arc part of the Oxygen (O2)
is converted into Ozone (O3). Ozone is very unstable and reverts back into
O2 within minutes. That is why ozone must be generated on-site and
cannot be shipped for later use. About one to ten percent of the oxygen
flowing past electrodes is converted into ozone. With air as the feed gas,
ozone concentrations between one and four percent are generated.
Ozone generators are an efficient means of water treatment. The energy
demand of a commercial ozone water treatment system is roughly the
same as a 50W light bulb. The overall energy consumption of the ozone
generator is dependent on: applied power, source oxygen flow, water
temperature, the manufactured efficiency and design of the generator.
(USEPA 1999)
5.4.3 Contactor
A contactor is the distribution system to evenly disperse ozone into water.
A contact chamber is the tank where ozone is introduced into the water.
To optimize water disinfection, ozone must be diffused as finely as
possible. The ability of a system to transfer ozone from a high
concentration (generator) to a low concentration (stored water) is called
mass transfer efficiency. The greater the efficiency, the less ozone
required for disinfection. Efficiency is increased by decreasing the size of
the ozone bubbles and the method in which ozone is introduced into the
water. (Rakness 1996).
Transbay Transit Center

5.4.4 Ozone Destruction Device
Ozone bubbles introduced in the water storage tank off-gas into a vent
pipe. The concentration of ozone being off-gassed from a water tank
generally exceeds the limit of 0.1 ppm, the current limit set by
Occupational Safety & Health Administration (OSHA) for worker exposure
in an eight-hour shift. For example, at 90 percent transfer efficiency, a 3
percent ozone feed stream has 3,000 ppm of ozone in the off-gas. Off-
gas is collected and the ozone converted back to oxygen prior to release
into the atmosphere. Ozone is readily destroyed at high temperatures (>
350°C or by a catalyst operating above 100°C) to prevent moisture
buildup. The off-gas destruction unit reduces the concentration to 0.1
ppm of ozone by volume. A blower on the discharge side of the destruct
unit pulls the air from the contactor, placing the contactor under a slight
vacuum to ensure that no ozone escapes. The power requirement is
between 1 to 3 kW per 100 scfm (standard cubic feet/min.) of gas flow.
(DeMers, 1996)
5.4.5 Ozone Safety Standards
Ozone gas is hazardous and should be handled accordingly. OSHA
regulates workplace safety standards, including allowable levels of ozone.
The pungent odor of ozone provides a warning to operators of any
possible ozone leak. Ozone is detectable by the human nose at 0.01-0.05
ppm (Reiff 1992). Instrumentation and equipment is provided to measure
ambient ozone levels and perform the following safety functions:
Initiate an alarm signal at an ambient ozone level of 0.1 mg/L (by
volume). Alarms include warning lights in the main control panel and
at entrances to the ozonation facilities as well as audible alarms (IO3A
2009).
Initiate a second alarm signal at ambient ozone levels of 0.3 mg/L (by
volume). This signal immediately shuts down ozone generation
equipment and initiates a second set of visual and audible alarms at
the control panel and at the ozone generation facility entrances. An
emergency ventilation system capable of exhausting the room within
a period of 2 to 3 minutes also would be interconnected to the 0.3
mg/L ozone level alarm (IO3A 2009).
In case of an electrical failure, the ozone generator shuts down along
with system pumps. An alarm powered by the emergency backup
generator sounds to notify personnel that the disinfection system has
been shut off. The alarm stops when power is restored to the ozone
generator. Ozone gas is vented out of the mechanical room. In case
of a rupture in the tank, negative air pressure in the tank causes air to
rush into the tank, preventing possible exposure to ozone.

5.4.6 Chlorine Injector
Chlorine is a common chemical disinfectant that when added to water,
leaves a detectable residual. Treated graywater is used to supplement
toilet flushing as long as there is a detectable chlorine residual of a least
1ppm at the toilet (IAPMO 2006). Chlorine breaks down over time as it
reacts with the water, air, and impurities. Chlorine can be added as a
powder, liquid, or gas. The most appropriate form of chlorine for the TTC is
liquid because the dosages can be closely controlled. Chlorine tablets
lead to variable concentrations, requiring higher application rates than
are required. High chlorine levels can lead to eye and throat irritation
during off-gassing.
To reach the minimum 1ppm of chlorine in treated water, an injector is
used to add liquid chlorine. The injector adds approximately 5ppm of
chlorine, exceeding the minimum requirement. The exact amount of
chlorine will vary as the flow rate varies. The chlorine injector modifies the
amount of chlorine used, which is determined by the variable pumping
rate (assuming a variable flow device is used).
The purpose of the chlorine injection is to ensure that the water is sterilized
before reuse in case any residual water pathogens are present. The
graywater and rainwater treatment systems function without the chlorine
additive, but including it complies with existing code requirements, and
minimizes liability for the TJPA. (IAPMO 2006)
Chlorine is a hazardous chemical, and should be handled with care.
Storage and handling of chlorine varies based on form and
concentration. Maintenance staff must follow the safety measures stated
by the manufacturer.
5.5 System Operation and Maintenance Manual
5.5.1 Graywater Maintenance
The water treatment system does not need to be registered under any
governmental or regulatory agency, but will undergo review and
inspection by local regulatory authorities if requested by the TJPA. The
TJPA, as owners of the TTC facility will own and operate the water
treatment system and have complete jurisdiction over the long term
maintenance of the system. The TJPA could also establish a third party
contract with a maintenance company.
Transbay Transit Center
Page 18
December 2014
5.5.2 Maintenance of Constructed Wetlands
1. Long-Term Maintenance
Subsurface constructed wetlands are biological systems and have
very few regular maintenance needs after they become established.
Wetland treatment systems rely largely on passive treatment
mechanisms and have very few operational controls compared to
mechanical treatment systems. They often run unattended for
extended periods of time. With proper wetland sizing and inlet and
outlet structure design, the wetland requires infrequent but regular
observation of the inlet zone, outlet zone and the adjustable weir.
Maintaining of wetland plants and gravel beds for aesthetics is similar
to any other planting area in the park; litter removal, pruning, plant
replacement, and fertilization may be required as part of the regular
landscape maintenance, but is not expected to require more
maintenance than a typical park planting area, depending on
planting design.
5.6 Operations Support
The TJPA, as owners of the TTC facility will own and operate the water
treatment system and have complete jurisdiction over the long term
maintenance of the system. The TJPA could also establish a third party
contract with a maintenance company.
6 Reliability
6.1 Automated Controls System
The entire reuse water system operation is fully automated through a
Programmable Logic Controller (PLC) based on programmed logic,
operator input and multiple sensors. Water level sensors (ultrasonic type),
located in all tanks in the treatment process sense various levels. Water
levels, flow rates and the operational status of pumps are monitored by
the system controls at all times.
A graphic user interface in the PLC system provides a visual indication of
all water levels, operating status of pumps, flow rates and other sensor
readings. Clearly labeled operator input fields and control points are
included in the graphic interface for each subsystem. In addition, alert
and alarm conditions are displayed on the alarm screen and forwarded
to operators. The alert/alarm conditions include a simple explanation of
the art/alarm cause. These features allow easy diagnosis of problems and
straight forward resolution.
Transbay Transit Center
Page 19
December 2014
The BMS will receive monitoring data and alarms from the Treatment
System, allowing building staff to review and respond to alarms 24 hours
per day, 7 days per week. The Treatment System alarm log is accessible
through the BMS both locally and remotely.
6.2 Treatment Process Reliability
The reuse water system includes proven treatment processes (for filtration
and disinfection). These processes are very reliable and overflows from
these tanks to the sewer provide an alternate outlet.
6.3 Hydraulic Control and Overflow Prevention
If a water level surpasses a predetermined maximum, the appropriate
overflow system will come into play. High water levels will be logged in
the PLC and flagged for operation review.
There are three water levels in the tanks that trigger overflow protection:
At the first level the three-way valve will divert the rainwater to the
gravity storm drainage.
As the second level overflow water pumps will pump the water into the
storm drainage.
At the third (highest) level the tank overflow will discharge indirectly
into the floor sink at next to the tank.
Critical high water conditions will trigger an alarm that will be broadcast
to designated operations staff.
All critical points in the system are equipped with emergency overflows or
bypass pumps to prevent uncontrolled overflow of graywater. Because of
these safeguards there is virtually no chance of overflow into equipment
rooms.
Graywater is pumped to each of the two wetland cells at a constant rate
of ~2.5gpm, thus under normal operation, the wetland will discharge
through each weir at a constant rate. Wetland weir inlets/outlets are 4”
diameter and sized to accommodate the design storm. As an additional
failsafe wetland cells are equipped with a four inch overflow drain so that
the water in the wetland will never surface. The wetland overflow drain
discharges back to the storage tank.
Transbay Transit Center
Page 20
December 2014
6.4 Supply Reliability
The system will reliably supply water to toilets and urinals. If the water level
in storage tanks drops to a certain level, potable water make-up supply
will be delivered. In the event of a power failure, all pumps and controls
are supplied with emergency power provided by on-site emergency
generators.
7 Supplemental Water Supply
In the event that the reuse water system is incapable of producing
enough treated graywater to meet the non-potable water demand for
toilets and urinals in the building, there are two supplies of make-up water:
Potable water supplied via the City’s potable water distribution
network.
Recycled water (Title 22, tertiary treated water) supplied by the future
recycled water distribution network.
Potable water can be delivered to the non-potable storage tanks in the
building when a low water condition in the tank triggers a valve to open
and fill the tank to a safe operating level. Water level sensors and valves
are controlled by the Treatment System PLC panel. Potable water is
delivered through an air gap to ensure no cross contamination to the
City’s potable distribution network.
8 Monitoring Reporting
Monitoring and sampling recommendations for this project will be
developed by the SFDPH. The sole use of reclaimed water in this system is
toilet and urinal flushing.
Table 4 provides a list of critical parameters with anticipating effluent
concentrations and sampling frequency to ensure proper operation and
performance of the system.

9 Contingency Plan
The contingency plan describes system features and operational
procedures that will be employed to prevent spills and system
malfunctions. The plan for provision of supplemental water supplies is also
described.
9.1 Flow Diversion
Diversion of flow to sewer can occur at several points as listed below:
Excess rainwater to three-way diversion valves.
Treated graywater transferred to other tanks (manually operated
valves).
Wetland overflow to the treated graywater tank.
Diversion of flow at these points is automatic under certain conditions and
can also be initiated by operations staff through the control system or
manual override. Level sensors in all tanks or wetland cells detect when
water reaches a critical level. In these cases, water will overflow or can
be diverted to the sewer. The conditions for diversion and the method are
outlined in Table 5.

In the event of a power failure the equipment will be supplied with
emergency power provided by on-site emergency generators. Also the
BMS will receive data and alarm signals from the treatment system.

10 Public Access and Impact
The Reuse Water Treatment System components are located primarily in
the basement mechanical rooms. The wetlands are contained in
watertight concrete basins with an above grade portion similar to
landscape planters. The treatment wetlands surface portions will be
located in the roof park area.
Public contact with wastewater and/or graywater aerosols will be
prevented by various measures, as described below.
Treated graywater will not surface in the wetlands, but is kept below
the surface medium (gravel-like material).
Plants will grow in and cover most of the wetland surface, acting as an
additional barrier to contact.
Because the wetlands will be filled slowly from the bottom or
subsurface manifolds, there will be no spraying or splashing of the
water that would release aerosols.
The dry gravel medium above the water surface will prevent any
droplets from becoming airborne.
The installation of warning and interpretation signs at all public access
points including planters and mechanical components.
The wetlands will not generate objectionable odors outdoors. Odors are
prevented by the design of the wetland process. Treated graywater is
always brought into the wetlands subsurface and odor compounds are
captured by the microbial bio films on the medium above water surface.
The wetlands will also be used as a public education tool with respect to
the water reuse systems and methods of treatment.
In the public restrooms, where treated graywater will be used for toilet
flushing, signage will be consistent with Use Area Requirements as
described in 60310 of CCR Title 22 and Dual-Plumbed Recycled Water
Systems as described in 60313-60316 of CCR Title 22 with the term
“Recycled Water” replaced with “Nonpotable Water”.

Overview
1 General System
Whenever the rainwater in the storage tank is above the minimum
operating level, the rainwater reclamation/filtration system will operate on
a cycle timer to draw water from the storage tank through a strainer and
pump it through a 25 micron auto-backwashing filter media and Ozone
injection chamber(s) and back to the storage tank as disinfected water.
2 Normal Operation
Water level in the storage tank is measured by an ultra sonic level sensor
to determine if there is sufficient water to run the reclamation system. If
tank level is too low, the control system indicates a “low tank level”
condition and opens the make-up water valve.
The auto-backwashing filter has a differential pressure indicator/switch
which will initiate a backwash cycle if the pressure drop exceeds 9 psid.
From the filter output the water passes through an Ozone injection
chamber and then returned to the storage tank. An Oxygen Reduction
Potential (ORP) sensor in the storage constantly monitors the ORP and
cycles the ozone generator to maintain ozone concentration in the range
of 0.1 to 0.5 ppm.
3 Alarms
The alarm will be activated in the event that:
The ozone generator fails, manual reset
The ORP reading is low, automatic reset(a)
Any time the system is on Fresh (not Gray) water, automatic reset(b)
Pump “Over Temp” sensor is tripped, manual reset
Notes: (a) This is a normal condition, not a system fault. When the storage tank
ORP level is back within range, the alarm will automatically clear
allowing the system to return to normal operation.
(b) This is a normal condition, not a system fault. When the storage tank
level rises to or above the normal operating level, the alarm will
automatically clear allowing the system to return to normal
operation.

1. The designer must determine the total system gpm typically using the combined cold and hot water fixturecount and then converting this to gpm using the Hunter curves.2. The designer then determines the required system boost pressure typically by adding the static lift for the highest fixture, the system friction loss at the maximum flow, and the minimum required inlet pressure of the fixturewith the highest inlet pressure requirement and then subtracts the minimum suction pressure supplied to thebooster system. Do not forget to also add the booster system pressure drop to the system boost pressure. Thiscan be determined by using the booster system Cv shown in the Pressure Booster Details Table.
Booster System Pressure Drop Equals: AP = (QICv)2
AP Booster System Pressure DropQ Booster System Maximum Flow RateCv Booster System Flow Coefficient
4. Using the pressure booster selection chart select a flow capacity that is equal to or the next larger flow required by the system. Select the pressure boost equal to or the next higher pressure required by the system.5. As an example select a duplex system that will produce 230 gpm at a pressure boost of 95psig. The modelnumber is a FMV2-9.6. Go to the Duplex Pressure Booster Detail Table and find that this model consists of two ITT 335VB-3/1 pumpswith 1 5HP motors, 2.5” check valves, 4” headers and has a system Cv of 75.7. System dimensions are shown on the Duplex Pressure Booster Dimension Table. Certified drawings should berequested for construction coordination

NOTES
These valves are full port and do not have the Optimizer insert.Close-Off Pressures measured with 35 in-lb. actuator. The tlose Off Pressure” is the maximum allowable pressure drop across the valvebody when the valve is fully closed. (Do not use actuators with torques higher than 90 in-lbs)
Cv is defined as the quantity of water in GPM at 60°F that will flow through a given valve with a pressure drop of I PSI. Hence the 1.0 PSIpressure differential column in the table above is equivalent to the Cv value.
