Review of Recycled Water Program
Capital Projects Committee Meeting - September 6, 2007
The District is continuing efforts to increase recycled water use by developing cost-
effective projects and encouraging innovative recycled water use where feasible. The
following is a summary of current activities.
New Connections within the Zone 1 Proiect Area
1. CONCO Corporation Yard (located on the former IT Corporation property)-
recycled water will be used for CONCO's new truck washing facility, which is
scheduled to begin operations in September 2007.
2. Pleasant Hill Demonstration Garden - The Mt Diablo Unified School District
(MDUSD) in cooperation with the Master Gardeners is constructing a
demonstration garden near Pleasant Hill Middle School that will be irrigated with
recycled water. The garden is expected to be completed in October 2007 and
will demonstrate the use of Integrated Pest Management (IPM) gardening
techniques and the use of native ornamental plants.
3. Colleoe Park Hioh School- West Ball Fields - CCCSD is evaluating a project to
convert the west ball fields at College Park High School to recycled water. Staff
is currently preparing a construction cost estimate and will be evaluating the
payback period for this new connection.
4. Blum View Estates - the developer of a 30 home subdivision near Blum Road
would like to use recycled water to irrigate common area landscaping. Staff is
evaluating this connection to determine if it is cost-effective and feasible. The
first homes are scheduled to be completed in Spring 2008.
Walnut Creek Recvcled Water
City staff recently contacted CCCSD about the possibility of providing recycled water
service to redevelopment projects planned for the downtown area (located in EBMUD
service area). Preliminary evaluations by EBMUD indicated that it is not cost-effective
to provide recycled water service to this area either by extending our existing pipelines
or with satellite treatment facilities. This is because our distribution pipelines are
located several miles away, and there is insufficient demand to justify the high cost of
extending our pipelines or constructing a satellite treatment facility.
EMBUD is currently in the process of updating their Water Supply Management
Program and are now taking public input. Staff recommends that CCCSD provide a
letter of interest to EBMUD indicating our support and willingness to work with them to
develop cost-effective recycled water projects within the portion of their service area
CCCSD also serves. Conditions may change in the future due to drought or changes in
water supply pricing that could make Walnut Creek or other locations within the EBMUD
service area more attractive.
A-Line Recycled Water Extension
As part of the A-Line Relief Interceptor Project (Phase 2A), CCCSD had planned to
extend our recycled water pipelines into the Meridian Park Blvd and Galaxy Way area of
Concord (near the Hilton Hotel) for landscape irrigation at businesses in this area. This
project was initially shown to be cost-effective with an estimated payback period of 11-
12 years, which is within our targeted 15-year payback period.
However, the Contra Costa Water District (CCWD) has stated they will imposed their
backflow prevention requirements (double check valves) for potable firewater service
connections at these sites. It appears this will make the project prohibitively costly. The
California Department of Health Services (the state agency that regulates backflow
prevention and cross connections) does not require additional backflow prevention for
this type of recycled water connection, and many other water agencies in California also
do not require it. Since CCWD had not previously required additional backflow
prevention devices for these types of recycled water retrofit connections, we did not
include the costs of these devices in our original cost evaluation for the project. Staff
had coordinated the project with the CCWD Operations Department, and when it was
review by the Planning Section, Planning staff state that addition backflow protection
would be required as call for in our agreement.
Because our estimate for the additional backflow prevention devices was much higher
than CCWD, we conducted a pilot study evaluation of the Chevron Office Complex (a
representative customer connection in this area) to confirm the costs and technical
feasibility of complying with CCWD's new requirements. Based on the results of this
study, we concluded that the A-Line Recycled Water Extension Project does not have a
15-year payback with the more stringent backftow prevention devices required by
CCWD. Consequently, staff will be recommending to the Recycled Water Committee
that either CCCSD approach the users to determine if they will pay a connection fee to
help offset the cost increase or that this project not move forward at this time. A formal
report on the findings of the Chevron pilot study will be provided at the next Board
Recycled Water Committee meeting planned for October.
Reaionallndustrial Recycled Water Study
CCCSD is participating in a Regional Industrial Recycled Water Study with the Delta
Diablo Sanitation District and several other east county agencies to evaluate options for
providing recycled water to industries in East County. In particular, Mirant is
considering constructing two new power plants in the Pittsburg/Antioch area that could
use large amounts of recycled water year round for cooling water (8-16 million gallons
per day). Delta Diablo does not have sufficient recycled water available to supply this
potential new demand. One alternative being considered is to convey our secondary
2
effluent to East County using an abandoned petroleum pipeline. The Regional
Industrial Recycled Water Study is scheduled to begin in October 2007 (pending
approval of a State grant application) and be completed in March 2008.

POSITION PAPER

Board Meeting.Date: September 6, 2007 No.:
Type of Action: AUTHORIZE FUNDS
Subject: APPROVE SUPPLEMENTAL AUTHORIZATION OF $1,900,000 TO THE
GENERAL IMPROVEMENTS PROGRAM OF THE FISCAL YEAR 2007-08 CAPITAL
IMPROVEMENT BUDGET
Submitted By:
Gail Chesler, PhD, Associate Engineer
Initiating Dept./Div.:
Engineering I Environmental Services
REVIEWED AND RECOMMENDED FOR BOARD ACTION:

ISSUE: Approval by the Board of Directors is required for a Supplemental Authorization
to the Fiscal Year (FY) 2007-08 General Improvements Program Budget.
RECOMMENDATION: Approve a Supplemental Authorization of $1,900,000 from the
Sewer Construction Fund for the General Improvements Program of the FY 2007-08
Capital Improvement Budget (CIB).
FINANCIAL IMPACTS: This supplemental authorization will allow currently planned
projects to continue. There are sufficient funds in the Sewer Construction Fund for this
supplemental authorization.
AL TERNA TIVES/CONSIDERA TIONS: If this Supplemental Authorization is not
approved, several General Improvements Program projects will be delayed until
FY 2008-09, and FY 2007-08 expenditure targets will not be met.
BACKGROUND: Each year, as part of the CIB adoption process, the Board of
Directors authorizes funding levels for each of the four capital programs: Treatment
Plant, Collection Systems, General Improvements, and Recycled Water. The Board
authorized $3,948,000 for the General Improvements Program for FY 2007-08, which is
a re-authorization for project carryover allocations and authorization for new allocations
for projects. Thus the FY 2007-08 authorization is the sum of project carryover and
funds for new allocations. If the carryover is more than projected in the CIB (which was
prepared three to five months before the end of the fiscal year), there is less money to
allocate for projects. This is the case for the General Improvements Program for FY
2007-08.
The need for the increased authorization arises principally from the underestimate of
actual carryover of the Equipment Budget and three other projects from the prior fiscal
year. Less money than estimated was actually spent. The result is that the increased
carryover diminishes the amount of money that can be allocated for new projects.

POSITION PAPER
Board Meeting Date: September 6, 2007
Subject. APPROVE SUPPLEMENTAL AUTHORIZATION OF $1,900,000 TO THE
GENERAL IMPROVEMENTS PROGRAM OF THE FISCAL YEAR 2007 -08 CAPITAL
IMPROVEMENT BUDGET
The four projects are:
. Equipment Budget - two large vehicles could not be purchased until FY 2007-08
. Collection Systems Operations Department Facility Improvements-
expenditures were delayed while developing an approved project description
. Headquarters Offices Building Improvements - expenditures were delayed due
to HV AC project delay
. Plant Operations Department Office Improvements - expenditures were delayed
due to HV AC project delay
The increased carryover for these projects was $1,900,000. These projects need to
proceed, so an increased authorization is required to fund other General Improvements
projects, such as the Equipment Budget for FY 2007-08 and right of way purchases.
The requested increased authorization is $1,900,000, which will offset the increased
carryover.
RECOMMENDED BOARD ACTION: Approve a Supplemental Authorization of
$1,900,000 from the Sewer Construction Fund for the Fiscal Year 2007-08 General
Improvements Program.
