Walnut Creek Water Treatment Plant Pretreatment Project Design Services

I. STATEMENT OF WORK

A. PURPOSE

The East Bay Municipal Utility District (EBMUD or District) supplies high-quality drinking

water to 1.4 million customers in the San Francisco Bay Area. The District’s Walnut

Creek Water Treatment Plant (WCWTP) is a 115 million-gallon-per-day (MGD) facility

located in Walnut Creek, CA. The WCWTP Pretreatment Project (Project) will add

treatment processes to the WCWTP, including ballasted flocculation, ozone, solids

handling, and supporting electrical power and maintenance facilities.

It is the intent of these specifications, terms, and conditions to request proposals for

consultant services for the Project. Given the size, complexity, and length of the overall

schedule required to complete the Project, EBMUD plans to take a phased approach by

negotiating and issuing three separate consultant contracts as shown in Table A.

After RFP proposals evaluation, EBMUD will select and retain the services of a

consultant or team of consultants that it deems best qualified to support the Project.

EBMUD will negotiate with the selected consultant or team of consultants to finalize a

detailed scope of work and budget for Contract #1 to complete the pre-design for the

Project.

EBMUD anticipates that Contracts #2 and #3 will be negotiated and awarded in the

future. The details of these future contracts will be based on the pre-design work in

Contract #1, which will provide EBMUD information to assess the full design scope of

the Project. Table A shows the anticipated schedule for Contracts #2 and #3.

EBMUD intends to retain the same consultant throughout Contracts #1, #2, and #3 of

the Project to provide continuity. However, EBMUD retains the option of negotiating

contracts with a different consultant for Contracts #2 and #3 contingent upon EBMUD’s

needs for the Project. EBMUD may decide to issue multiple contracts with varying

scope to multiple proposers depending on the needs of the Project and experience of

proposers.

B. BACKGROUND

The WCWTP is located at 2201 Larkey Lane in Walnut Creek, CA. It was originally

constructed in 1967 to treat Sierra Mountain snowmelt water stored in Pardee

Reservoir and conveyed to the EBMUD service area by the Mokelumne Aqueducts.

Where the Mokelumne Aqueducts connect to the WCWTP, the WCWTP has separate

north and south treatment trains. Each treatment train includes a raw water pipeline,

pH adjustment, rapid mix, and dual-media filters. The north and south trains flow into a

combined filtered effluent pipeline, then into a 4 million-gallon (MG) chlorine contact

chamber and a 16 MG clearwell. The WCWTP also has a spent filter backwash water

reclaim system and a solids storage basin. The WCWTP is permitted for 115 MGD and

primarily serves the District’s East-of-Hills area, with emergency interties to neighboring

water agencies. In recent years, source water quality has periodically degraded due to

fires in the watershed, high-intensity storms, algae blooms, and utilization of drought

water supplies. The WCWTP has limited ability to treat incoming source waters that can

contain high levels of sediments, organic compounds, and other pollutants.

The Project will construct new pretreatment facilities that will remove sediments,

organics, and pollutants in the source water and ensure reliable drinking production

under a wide range of source water conditions. Figure 1 shows the location and

approximate footprint of the proposed pretreatment facilities and ancillary

improvements at the WCWTP site. Construction will be completed in two phases. Phase

1 will upgrade one treatment train, adding 80 MGD of pretreatment capacity and

increasing total WCWTP capacity to 125 MGD. Phase 2 will upgrade the second

treatment train for a total pretreatment capacity of 160 MGD and is a future

construction phase that will be scheduled as needed to supply service area demands.

Figure 2 is a schematic that shows the planned treatment process upgrades.
