CITY COUNCIL AGENDA ITEM NO. 5

Meeting Date: August 23, 2005

Subject/Title: Adopt a Resolution authorizing the City Manager to execute an Agreement between the Contra Costa Water District and the City of Brentwood for a Temporary Connection to the Randall-Bold Water Treatment Plant.

Prepared by: Engineering: P. Eldredge

Submitted by: Engineering: B. Grewal

RECOMMENDATION
Adopt a Resolution authorizing the City Manager to execute an agreement between the Contra Costa Water District and the City of Brentwood for a temporary connection to the Randall-Bold Water Treatment Plant to deliver treated water to the City of Brentwood.

PREVIOUS ACTION
On August 12, 2003, City Council approved Resolution No. 2947, authorizing the City Manager to execute the amendment to the agreement with the Contra Costa Water District (CCWD) pertaining to treated water services.

On August 12, 2003, City Council approved Resolution No. 2944, authorizing the City Manager to execute a professional services agreement with Raines, Melton & Carella, Inc., for the design contract for the Surface Water Treatment Facility – Phase I, CIP Project No. 562-5629.

On August 24, 2004, City Council approved Resolution No. 2004-206, authorizing the City Manager to execute an agreement with the Contra Costa Water District pertaining to long term treated water services as a part of the Surface Water Treatment Facility - Phase II, CIP Project No. 562-5629.

BACKGROUND
The City of Brentwood currently pumps water from the Randall-Bold Water Treatment Plant (RBWTP) through a pipeline owned and operated by the Diablo Water District (DWD) under a separate existing agreement. As the City of Oakley continues to grow, which is essentially DWD’s service area, there will become less capacity available in the pipeline currently utilized by the City of Brentwood. It was always understood that this wheeling agreement was to be an interim solution until the City of Brentwood could initiate its long term water treatment, pumping and piping options. Although DWD has been cooperative with the City of Brentwood in regards to water deliveries under this existing agreement, there are unavoidable infrastructure limitations to the amount of water available. Phase I of the long term solution (pipeline and pumpstation) is currently under construction and is estimated to be fully functional in early 2006. However, until this pumpstation is complete, the City of Brentwood has determined that an interim connection to a Contra Costa Water District (CCWD) pumpstation is prudent to ensure adequate reliablae potable water capacity is available to the City of Brentwood.

The treated water delivered from RBWTP will be through a temporary connection to CCWD’s Multipurpose Pipeline (MPP) pumping station and a temporary pipeline connecting to the City of Brentwood’s recently installed 42” distribution line.

It is the intent of both the City of Brentwood and CCWD to enter into this agreement to define the terms under which CCWD shall deliver treated water from RBWTP, as well as establish the roles, responsibilities for the operations, construction and financials pertaining to this interim connection.

FISCAL IMPACT
The project team for the Surface Water Treatment Facility – Phase I, CIP Project No. 562-5629, have been successful in negotiating the scope of work with the contractor currently constructing this project; thus, staff is not requesting authorization for additional expenditures as the estimated amount is within the 10% contingency granted at the time the construction contract was awarded.

Per the existing agreement with DWD the City of Brentwood pays monthly for wheeling charges based upon the quantity of water pumped. The amount currently billed per acre-foot is variable, dependant upon PG&E power costs amongst other things; however, on average it is approximately $38.50 / acre-foot. Per previous agreements with CCWD the City of Brentwood has a certain capacity right in some of CCWD’s facilities such as the MPP. The current capacity right is 1,342 acre-foot for which the City of Brentwood pays only the power and chemical costs associated with pumping the treated water, which has been estimated at $24 / acre-foot. Any water pumped over and above the 1,342 acre-foot will be billed at $76 / acre-foot, as it also includes rental of the facilities. Taking the anticipated water usage into account over the next several months, the average cost for the CCWD water is $32.29 / acre-foot. Staff is requesting that it be given the authorization to pay CCWD for this service as outlined above and in the attached agreement. As shown above, this cost will be less than currently paid to DWD under the existing agreement, thus not having any detrimental fiscal impacts.

There will be no change to the cost associated with the treating of the City of Brentwood’s water at the RBWTP.
