RECOMMENDATION
Approve a Resolution authorizing the City Manager to execute a Professional Services Agreement with Raines, Melton & Carella, Inc., to provide Design Services for Chloramination of Wells, CIP Project No. 562-5617, in the amount of $143,022, plus a 10% contingency and amend the CIP Budget Sheet.

PREVIOUS ACTION
On May 28, 2002, by Resolution No. 2549, City Council adopted the City’s 2002/03 – 2006/07 Capital Improvement Program that included Chloramination of Wells, CIP Project No. 562-5617.

On May 27, 2003, by Resolution No. 2868, City Council adopted the City’s 2003/04 – 2007/08 Capital Improvement Program that included Chloramination of Wells, CIP Project No. 562-5617.

On May 25, 2004, by Resolution No. 2004-113, City Council adopted the City’s 2004/05 – 2008/09 Capital Improvement Program that included Chloramination of Wells, CIP Project No. 562-5617.

BACKGROUND
The City has been working on securing a long term treatment option for its surface water supply obtained from the East Contra Costa Irrigation District (ECCID). The City has entered into an agreement with the Contra Costa Water District (CCWD) to provide interim treatment services of this water and has since purchased existing capacity at the Randall-Bold Water Treatment Plant (RBWTP) and has begun the planning process for a new treatment facility adjacent to RBWTP in partnership with CCWD.

The City currently uses chlorine as its potable water disinfectant for the groundwater pumped from the City’s wells. As groundwater is low in naturally occurring organic matter, chlorine is a suitable choice; however, surface water such as that taken from the Delta (Brentwood’s ECCID supply) is generally higher in organic material. Most of the organic material is removed during the treatment process; however, a very small amount could remain. These organics, when mixed with chlorine, have the potential to form a compound known as Trihalomethanes or THM’s, which are a carcinogenic to humans. Thus, chloramamines are used instead of chlorine since they do not form THM’s. Chloramamines are produced by mixing a small amount of ammonia with the chlorine. The City has been utilizing this surface water supply for several years now; however, the volume of water used has made it more cost effective to remove the ammonia from the surface water supply before it is mixed with Brentwood’s well water through a process known as “break point chlorination.” As the City continues to grow this process will no longer be cost effective for the City; therefore, the City’s groundwater supply needs to be converted to chloramamines.
Raines, Melton and Carella, Inc. (RMC) services have been obtained to assist City staff in preparing the necessary construction documents for this conversion, as well as provide assistance to the City on a public notification process. RMC has extensive background in this sort of work and has provided public notification assistance to various other water agencies in northern California. Samples of the type of public notifications the City will be sending out to the residents is attached to this staff report. This outreach will be accomplished via mailings in water bills, newspaper ads and various other means.

FISCAL IMPACT
Included in this proposal is design of the facilities, public outreach assistance, services during construction and record drawings. The total cost of this proposal is $143,022, which has been included in the approved 2004/05 - 2008/09 Capital Improvement Program Budget; however, the funds for the project administration, management, design and construction were included in fiscal years 2005 and 2006 respectively. Therefore, the CIP budget sheet needs to be modified to reallocate the budget from 2005 and 2006 to this current fiscal year.

This amendment has been discussed with the appropriate individuals in the Finance Department and pursuant to this conversation it was determined that this budget amendment would not have a negative impact to the cash flow or ending balance for these aforementioned fiscal years and does not financially preclude the City from completing future planned projects.
