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


Page 2

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.

4.3 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.


Page 7

December 2014

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.


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.


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).


Page 16

December 2014

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.


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.


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.


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.

The building evacuation and protection procedures for natural disasters

will be provided by TJPA.

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.
