RECYCLED WATER PROGRAM OVERVIEW
This annual report covers Central Contra Costa Sanitary District's (Central San's)
production and distribution of recycled water for calendar year 2016. Central San has
provided tertiary-treated recycled water to serve in-treatment-plant usage, irrigation
customers, and a range of commercial uses since 1006.
In 2016, Central San produced a total of 534 million gallons (MG) (1639 acre-feet (AF))
of recycled water. Central San's main treatment plant continued to be the biggest user
of this recycled water; in 2016, Central San used approximately 316 MG (971 AF), of
recycled water internally at the treatment plant for process water and landscape
irrigation. In addition, approximately 217 million gallons (MG) (667 acre-feet (AF)) of
recycled water was distributed offsite to a variety of customers in Pleasant Hill, Concord
and Martinez near Central San's treatment plant in Martinez. Recycled water was used
for landscape irrigation at schools, parks, private businesses, golf courses, and street
medians, and for commercial applications such as truck washing, concrete
manufacturing, dust control, and toilet and urinal flushing.. Table 1 of this report
provides a summary of recycled water usage by offsite customers in 2016 by reuse
application category, as requested by the Regional Water Control Board (Regional
Board). Table 2 shows the monthly usage of recycled water by customer. Table 3 lists
Central San's three new authorized recycled water users for 2016. Figure 1 is a map of
our existing recycled water distribution system, which includes the location of each
recycled water customer.
All laboratory recycled water sampling and analyses were performed in accordance with
Regional Board Order 96-011, and Central San's Recycled Water Program complied
with all applicable tertiary recycled water quality standards. Tables 5 through 15
present monthly recycled water quality characteristics for 2016. All Central San
recycled water customer sites were inspected by central San field operations staff and
found to be in compliance with recycled water use regulations; copies of those
inspection reports can be found at the back of this report.

ACTIVE RECYCLED WATER PROJECTS AND PROGRAMS
Central San continues to explore opportunities, seek partnerships, and pursue funding
assistance to cost-effectively expand recycled water use. Central San has expanded its
Recycled Water Program to include pipeline delivery, a Truck Fill Program, and a
Residential Fill Station. Those projects and Programs are described more fully below.
Recycled Water Zone 1 Pro'ect
In 1996, Central San executed an agreement with Contra Costa Water District (CCWD)
that allows Central San.to purvey up to 379 MG/year (1,163 AF/year) of recycled water
for landscape irrigation and light industrial uses in Zone 1, which consists of a specific
geographic area in portions of Martinez, Pleasant Hill and Concord near Central San's
treatment plant. Central San invested in upgrades to its existing Filter Plant in order to
provide Title 22 quality recycled water, and installed purple recycled water pipelines and
began serving our first off-site customers in 1998. Since that time, Central San has
continued expanding the distribution system and connecting new customers in Zone 1,
which now consists of approximately 13 miles of recycled water distribution pipelines in
these areas and now provides recycled water service to more than 50 metered
customer use sites.
In 2016, Central San was delivered 188,988,460 gallons of recycled water to customers
connected to our recycled water distribution system in the Zone 1 project area, Central
San will continue efforts to identify and connect additional cost-effective recycled water
customers in this project area.
Concord Recycled Water Project
The Concord Recycled Water Project was the largest remaining recycled water project
within the Zone 1 area. In early 2014, construction of the mainline distribution system
was completed, and laterals to 36 potential recycled water customers were installed.
This system was charged in Spring 2014, and a recycled water hydrant within the
project area was made active for serving our Truck Fill Program, which is described on
the next page.
In the summer of 2015, Central San hired a contractor to complete the connection of 14
new business customers, and convert their existing landscaping irrigation to recycled
water. In 2016, Central San completed the connection of two additional recycled water
connections in this project area —the Concord Hilton for landscape irrigation, and the
future Golden State Lumber site for use during construction and site development for
this new business. Once completed, Golden State Lumber will also use recycled water
for landscape irrigation. See Table 3 for a listing of these new customer sites, along
with their expected annual recycled water demand.
The Concord Landscape Project was previously awarded a $1,030,000 Proposition 84
Implementation Grant from the California Department of Water Resources and a
2
$07,000 Title DCVI planning grant from the US Bureau of Reclamation (USER) in 2011.
Central San is continuing to seek federal legislative authorization and appropriation for
an additional $1.8 million in Title XVI funding for the project through the Western
Recycled Water Coalition (discussed later in this report).
Truck Fill Program
During the 2000 drought, CCWD implemented water conservation measures, which
included recalling its portable hydrant meters, so contractors were no longer able to
obtain water for construction activities in the northern part of Central San's service area.
To help address this need, Central San installed a fire hydrant on our recycled water
distribution system, purchased a supply of portable recycled water meters, and
implemented a Portable Hydrant Meter Program (Hydrant Program) to provide recycled
water to contractors and public agencies for dust control, compaction, irrigation, and
other non-potable uses. Customers are trained and issued a Use Permit and magnetic
recycled water notice placards to place on their water truck when hauling recycled
water. Meter readings are gathered monthly from these customers via email.
In 2014, Central San installed and activated a second hydrant as part of the Concord
Recycled Water Project to expand the reach of this Program. As drought conditions
worsened in 2015, CCWD once again limited issuance of its portable hydrant meters
and directed contractors to Central San's Hydrant Program, which resulted in the use of
4,370,022 gallons of recycled water—the highest usage ever recorded for Central San's
Truck Fill Program.
As drought conditions eased in 2010, so did CCWD's portable meter restrictions,
resulting in a decline in recycled water usage through Central San's Truck Fill Program.
In 2018, 416,438 gallons of recycled water were distributed through this Program.
There have been several challenges in meeting recycled water construction demands
with the Hydrant Program:
• The demand for recycled water from Central San's Hydrant Program has been very
limited when there are no drinking water drought restrictions in place.
■ Since portable meters have significant cost (~$1,000) and have very limited usage in
wet years, Central San staff has been hesitant to purchase a large supply of meters.
• In drought years, when demand escalates for the Hydrant Program, Central San has
had to maintain a waiting list for portable meters, as demand exceeded supply.
• Staff must collect monthly meter readings from current meter holders, which can
often be time-consuming.
■ When drought conversation targets are in place, theft of portable recycled water
meters is prevalent.
To respond to these challenges, and to further encourage use of recycled water for
construction activities, Central San's Board of Directors took the following actions;
3
• Approved the construction and implementation of a Commercial Recycled Water Fill
Station, which would allow users to fill water trucks via an overhead filling pipe that is
activated with a simple numeric code, and which automatically tracks the volume of
recycled water taken by each user
• Authorized the General Manager to waive the volumetric fee (currently $3.4811,000
gallons) assessed for recycled water obtained through the Truck Fill Program
The Commercial Fill Station was constructed in 2015, and opened to a limited number
of users while staff worked to refine operational issues. Central San will launch the new
Fill Station in advance of the 2017 construction season. With drought restrictions lifted
in CCWD's service area, the Commercial Fill station will likely not see high usage
immediately, but it does position Central San to better respond to future drought
conditions.
Residential Recycled Water Fill Station Program
In Fall 2014, Central San followed in the trail blazed by Dublin San Ramon Services
District and constructed the state's third Residential Recycled Water Fill Station
(Residential Fill station) at our Household Hazardous Waste Collection Facility
(HHWCF) in Martinez. The Residential Fill Station provides up to 300 gallons per trip of
recycled water to residents within Central San's HHWCF service area and Central San
employees at no charge. Participants are required to complete a Recycled Water Use
Application/Agreement and receive training prior to using the Residential Fill Station.
Participants may make unlimited visits to the Residential Fill Station during operating
hours. Recycled water distributed through this Program may only be used for hand-
watering lawns, landscaping and gardens, and may not be introduced into any
permanent piping systems that could lead to a cross connection.
While use of Central San's Residential Fill Station started off slowly, demand grew
exponentially throughout the irrigation season of 2015. Due to the increased demand,
Central San expanded the number of fill ports from three to seven, hired a temporary
staff of 15, and expanded our hours to seven days per week. By the end of 2015,
Central San's Residential Fill Station distributed almost 12 million gallons of recycled
water to our residential customers and Central San employees. With the easing of
drought restrictions in 2015, Central San's Residential Fill Station saw a significant
decline in participation. In 2018, the Program distributed 0,544,182 gallons of recycled
water and will continue operation in 2017.
PLANNING FOR FUTURE RECYCLED WATER PROTECTS
Wholesale Recycled Water Opportunities Study_
In June 2015, Central San hired RI IC Water and Environment (RMC) to complete a
study on opportunities for the District to wholesale large quantities of its potential supply
of recycled water to other users in and around the Bay Area. RIUIC completed the study
in early 2015, which identified four potential projects to pursue, including the Refinery
4
Project (with a third party buyer of the freed up water), an agricultural option which
would provide recycled water to the Delta Mendota Canal and two options for potable
reuse (either indirect or direct) via CCWD's and/or East Bay Municipal Utility District's
(EBMUD) nearby facilities to the Bay Area Regional Reliability Partners or another end
user in need of water supply. RMC also identified next steps to initiate discussions to
continue evaluating the feasibility of the four potential projects.
In 2010, Central San continued discussing these project concepts with potential
partners and will continue to do so in 2017.
Contra Costa Coun!y Refinery Recycled Water Project
Central San continues to be very interested in developing a refinery recycled water
project that would provide up to 22,500 A F/year (20 MG/day) of recycled water to the
Shell and Tesoro refineries in Martinez for cooling tower and boiler-feed water. The
refineries currently receive CCWD's untreated Delta water via the Contra Costa Canal,
which is predominantly supplied by the USSR's Central Valley Project (CVP). The
refinery project is particularly attractive because it represents a large year-round
demand for recycled water, and it could potentially make use of existing recycled water
conveyance and storage facilities already in place from Central San's treatment plant to
each refinery. The planning-level cost estimate for the refinery project could be up to
$100 million depending on whether the full-scale project is implemented. As a result,
Central San needs financial assistance and/or project partners to make the project cost-
effective.
In 2011, Central San was awarded an $180,000 Title XVI planning grant from the USER
to fund half of the cost to prepare a feasibility study and environmental documentation
for the proposed project. The USER requires the project sponsor to prepare a feasibility
study to demonstrate that the proposed project is viable, well thought.-out, and provides
a long-term source of water that justifies the expenditure of federal funds for
construction of the proposed facilities.
As an initial step in preparing the feasibility study, Central San, in partnership with
CCWD, hired RMC and MBIA Engineers to complete a water supply yield study on the
project. The yield study, completed in May 2013, determined that due to the limitations
in the capacity available in the operation of the CVP, the true yield of the refinery project
is just about half of what would be delivered (for either the 5 or 20 MG/day-sized
projects). The results of the study were reviewed by the USBR. Since the project
appears to be viable, Central San continued its contract with RMC to prepare a Title XVI
feasibility study, which was submitted to the USBR in December 2014.
In 2015, CCWD approached Central San to negotiate terms for a future agreement for
Central San to supply 0.5 MG/day of recycled water out of the current treatment
processes to serve a small portion of the cooling water demand at Shell Refinery.
CCWD was interested in this project as a way to meet their 20 percent demand by 2020
(20x2020) that is required by SB DC7-7. However, due to Shell's refusal to accept the
5
current quality of Central San's recycled water (contains ammonia and elevated salt
levels), this project concept has not moved forward.
In 2016, Central San continued supporting CCWD's efforts to evaluate the condition of
the existing industrial pipelines to Shell Refinery, which were constructed in the late--
1970s and used just twice during severe droughts in 1989 and 1991. CCWD is also
discussing the potential to obtain recycled water from Mt. View Sanitary District, which
is adjacent to the Shell Refinery. As of the writing of this report, it is unclear if CCWD
will be looking to Central San to serve any recycled water to either refinery, as a way to
meet 20x2020, but Central San continues to be interested and willing to serve.
Concord Naval Weapons Station Redevelopment
The planned redevelopment of the Concord Naval Weapons Station property provides
an excellent opportunity to expand recycled water use. In 2069, the City of Concord
selected a preferred development plan (clustered villages concept) consisting of a
mixture of commercial, residential, institutional, and recreational land uses interspersed
between parks and open space. This mixture of land uses will create opportunities to
use recycled water not only for landscape irrigation but also for non-potable uses such
as toilet flushing and cooling towers in commercial buildings.
The redevelopment of the property and construction of supporting recycled water
infrastructure is not expected to begin for five to ten years because of additional
planning work that must be completed by the City of Concord and the US Navy before
property ownership can be transferred from the US Navy to the City of Concord and/or a
developer.
In 2012, Central San completed a Draft Recycled Water Facilities Plan for the Naval
Weapons Station redevelopment that evaluated alternatives and costs for new recycled
water infrastructure needed to meet the anticipated demand. Recycled water demand
for the new development is estimated to be approximately 2,800 AF/year (900 MG/year)
at build-out.
In 2016, the City of Concord selected a Master Developer for the project, and planning
efforts are expected to begin in 2017. The current vision for serving this development is
for Central San to wholesale recycled water to CCWD, and CCWD would be the retailer.
Satellite Water Recycling_Facilities
Central San was first approached about the concept of a satellite water recycling facility
(SWRF) in 2009, when water supplies were limited due to drought. In 2012, Central
San entered into a three-way Memorandum of Understanding (MCU) with the Diablo
Country Club (DCC) and their water purveyor, East Bay Municipal Utility District
(EBMUD), to evaluate the feasibility of a satellite water recycling facility (SWRF) project
that would produce recycled water onsite for the irrigation of DCC's 18-hole golf course.
The proposed SWRF would divert wastewater from Central San's collection system and
6
treat it onsite at DCC's golf course in a small membrane bioreactor (MBR) recycled
water treatment plant. The recycled water would be stored in onsite storage ponds and
the MBR's process solids (2 percent) would be returned to Central San's collection
system.
In April 2015, Central San executed a two-party MOU with DCC that documented the
mutual agreement of Central San and DCC as to the benefits of a SWRF and to identify
and resolve technical issues to the mutual benefit of all parties at no net cost to Central
San. DCC also executed an MOU with EBMUD in 2015, to obtain EBMUD approval to
explore the project further, since EBMUD is the water purveyor for DCC and this project
would reduce their purchase of EBMU D's potable water.
In August 2010, Central San and DCC executed a Planning Agreement, which
documents the mutual understanding of anticipated roles and responsibilities for each
party in the evaluation, development, and potential implementation of the DCC SWRF
Project, and commits Central San to being the Lead Agency in conducting the California
Environmental Quality Act (CEQA) environmental review process. If the CEQA process
yields an implementable project, the project will be developed under a Design-Build
contract issued by DCC, and implemented like a developer project, whereby DCC will
fund and construct the project, then turn over the facilities to Central San to own and
operate. If that comes to fruition, DCC will be responsible for reimbursing Central San
for all costs to own, operate, and maintain the SWRF facilities. Major activities
anticipated in 2017 include procuring the Design-Build entity and completing the CEQA
process. DCC is striving to have the project operational in 2018.
In addition to DCC, Central San has also been approached by the Moraga Country Club
(MCC) regarding the development of a SWRF project. In July 2010, Central San
executed a three-way MOU with MCC and EBMUD for a SWRF facility at MCC, with the
key difference being that the proposed wastewater diversion would be from Central
San's Moraga Pump station. MCC has not indicated a desire to advance their project
at this time, but is watching with interest as the DCC project unfolds.
Development of Recycled Water Pro'ects on Central San Buffer Property
Central San has been exploring options for recycled water projects on the vacant buffer
land owned by Central San near our treatment plant facilities in Martinez. In 2014,
Central San issued a lease to the nonprofit organization AgLantis for the use of
approximately 15 acres of Central San buffer property for growing food crops with
Central San recycled water. The food crops will be donated as fresh produce to school
lunch programs and the nearby Contra Costa Food Bank. The project will be used to
demonstrate the science and benefits of recycled water and sustainable gardening and
farming practices (e.g., avoiding the use of pesticides and other toxic products). The
project could potentially serve as a model for other wastewater agencies that have
available land near their treatment plant facilities and would like to increase water
recycling. The project received its County Land Use Permit in late 2015. Once
irrigation plans are designed and submitted, Central San will submit an Engineering
7
Report for approval of this use by the State Water Board's Division of Drinking Water
and the Regional Board. There was no recycled water activity on this project in 2016.
OPERATIONS AND MAINTENANCE UPDATE
Recycled„Water Treatment Facilities
Due to very steady operation in Central San's treatment plant in 2016, Central San's
Recycled Water Filter Plant also had a very steady operation. All recycled water
produced by Central San in 2016 complied with all applicable tertiary recycled water
quality standards.
Recycled Water Distribution System
Central San field crews continued operation and maintenance of Central San's recycled
water distribution system in 2016. When needed, Central San relies on CCWD field
crews to perform repair work on Central San's recycled water distribution system under
a maintenance contract that we have had with CCWD since 2004. CCWD's cross
connection control specialists also assist Central San with cross connection inspections
for new recycled water sites, and testing and recertification of existing sites where
piping modifications have been made. Central San's Maintenance Crew Leader
obtained certification as a Cross Connection Control Specialist in 2013, and has been
certifying Central San's cross connection tests since that time.
In 2016, Central San had no reportable recycled water spills.
CUSTOMER TRAINING
Central San has an ongoing Customer Training Program to educate recycled water
customers about the precautions and appropriate uses of recycled water, and to train
new Recycled Water Site Supervisors. In addition to training new customers before
they connect to our system or begin using our recycled water, Central San also provides
training when there is a turnover in the Recycled Water Site Supervisor. During annual
site inspections, Central San provides refresher training to customer staff where needed
and verifies that each customer has up-to-date training materials, including Central
San's brochures and guidance documents on the proper use of recycled water.
REGIONAL ALLIANCES TO DEVELOP RECYCLED WATER PROJECTS
Western._Recycled Water Coalition fformpLly BqX Area Recycled Water„Coalition
Since 2009, Central San has been a member of the Bay Area Recycled Water Coalition,
which is a partnership of 22 agencies committed to developing recycled water as a
resource for municipal, industrial, commercial, and agricultural uses across the San
Francisco Bay Area. In 2013, the Coalition expanded to include agencies outside of the
San Francisco Bay Area, so the name was adjusted accordingly to reflect that. The
8
Western Recycled Water Coalition continues a successful regional approach to pursing
recycled water funding and was instrumental in helping Central San to secure the Title
XVI planning grants for the Concord Recycled Water Landscape Project and the
Refinery Project. As part of Central San's support of the Coalition, Central San's
Graphic Artist designed a 0-page Coalition brochure to educate congressional leaders
about potential recycled water projects, attract new members, and provide updates as
projects and-agency members change. Central San continues to pursue Title XVI
recycled water funding for the Refinery Project Phase 1 (5 MGIC) and the Concord
Recycled Water Project.
Bay Area Integrated Regional Water Management Planning
In 2013, Central San collaborated with other Bay Area agencies to update the Bay Area
Integrated Regional Water Management Plan (BAIRWMP), which was originally
prepared in 2000. The BAIRWMP is a nine-county effort to coordinate and improve
water supply reliability, protect water quality, manage flood protection, maintain public
health standards, protect habitat and watershed resources, and enhance the overall
health of the San Francisco Bay. Projects listed in the BAIRWMP are eligible to apply
for state grant funding, such as Proposition 84 funding, which provided funding to
Central San's Concord Recycled Water Landscape Project. Central San recycled water
projects that are currently being implemented or may be initiated within the next three to
five years have been listed in the latest BAIRWMP update and include the Recycled
Water Zone 1 Project and the Contra Costa County Refinery Recycled Water Project.
SALT AND NUTRIENT MANAGEMENT PLAN COMPLIANCE
On February 3, 2009, the California State Water Resources Control (SWRCB) adopted
a Statewide Recycled Water Policy establishing uniform requirements for the use of
recycled water. Among other provisions, the Policy requires regions overlying
groundwater basins in the State where recycled water use is occurring and planned for
the future to develop a salt and nutrient management plan by May 2014. The SWRCB
has indicated its pians to develop a streamlined reporting process by which
groundwater basins with limited use of the groundwater resources, or basins not likely
to have adverse impacts from recycled water irrigation, can prepare simplified salt and
nutrient management plans. The specific reporting requirements continue being
developed by the SWRCB. As part of the BAIRWMP update process, templates have
been developed that will allow Bay Area agencies to prepare their salt and nutrient
management plans in an efficient and streamlined manner.
Due to the very limited use of groundwater for potable water supply in Central San's
service area, the basins underlying Central San's current and planned recycled water
service areas would qualify for the streamlined reporting process. For these areas, the
deadline for this requirement continues to be pushed out due to other more pressing
water quality priorities for State and Regional Board staff.
9
LIMITS To EXPANSION of RECYCLED WATER USE
There are many institutional and financial impediments outside of Central San's control
in expanding the use of recycled water. On the institutional side, Central San must work
with the potable water purveyors in our service area and either wholesale recycled
water to them or obtain their permission to purvey recycled water. Potable water
purveyors have significant sunk costs in existing facilities to serve water customers, so
the California duplication of services law allows them to recoup stranded costs if
recycled water is made available. Although recycled water producers may dispute the
applicability of this law, the issue can add another institutional barrier and significant
cost to recycled water projects.
Even when institutional issues are overcome, the cost to construct new recycled water
treatment and conveyance facilities can be high. New landscape irrigation projects
often require construction of purple pipelines through congested urban areas or
additional treatment facilities to increase recycled water production capacity. When all
of these costs are added together, the unit cost of recycled water almost always
exceeds the cost of other available, but less-sustainable, water supplies that externalize
many costs to the environment. Although recycled water projects may have substantial
additional quantifiable benefits versus conventional alternatives, additional sources of
funding are needed to make recycled water projects more competitive with cheaper
water supply alternatives available to local water purveyors. The high demand for
limited state and federal funding for recycled water projects has restricted the growth of
Central San's Recycled Water Program. Despite these challenges, Central San
continues to pursue development of new recycled ►mater projects that are economically
and financially viable.
