Current Recycled Water Users

Facilities at the RARE Water Project
The RARE Water Project at Chevron's Richmond refinery can produce 3.5 million gallons of recycled water a day

EBMUD currently provides recycled water to numerous sites for irrigation, commercial and industrial uses.


The North Richmond Water Reclamation Plant is EBMUD's first major project to produce recycled water for an industrial application. With a design capacity of 5.4 million gallons a day (mgd), it is one of the larger industrial cooling water reuse projects in the nation. In operation since 1996, the EBMUD facility receives secondary effluent from nearby West County Wastewater District, provides tertiary treatment, and sends the recycled water to three cooling towers located at Chevron's Richmond refinery. Chevron used almost 3.6 mgd of recycled water in Chevron's cooling towers in Fiscal Year 2014 (FY14).

EBMUD expanded its industrial recycled water program by constructing the Richmond Advanced Recycled Expansion (RARE) Water Project at the Chevron Richmond Refinery. The RARE Water Project can produce 3.5 mgd of recycled water and became operational in July 2010. RARE provides advanced treatment for secondary effluent piped from the West County Wastewater District. Facilities include microfiltration and reverse osmosis systems, storage tanks (up to 2-million gallons), and a variety of pumps, pipes and ancillary equipment. Chevron uses the recycled water in its boilers to generate steam to operate facilities and equipment used to manufacture gasoline, jet fuel, diesel and lubricants. Only extremely high-purity water can be used in the manufacturing process. Chevron used more than 3.3 mgd of recycled water produced by the RARE Water Project in FY14.

With water from RARE and cooling tower use of recycled water, Chevron can meet about 7.5 million gallons per day of its total water needs with recycled water instead of using EBMUD's limited potable water. That means 7.5 mgd of drinking water can be made available for all EBMUD customers for other purposes -- an amount that meets the daily indoor and outdoor water needs of more than 83,000 EBMUD residents.

Since the 1970s, EBMUD has maximized water recycling at its own Wastewater Treatment Plant (WWTP) for various uses, including cooling water, equipment wash down, mixing chemicals, and landscape irrigation. More than 2.4 mgd were recycled at our WWTP in FY14. Approximately 1.7 mgd of non-potable water is reused at EBMUD drinking water filter plants. EBMUD's Administration Building was retrofitted in 2008 to use recycled water for toilet flushing on the 2nd floor, to irrigate street trees and street-level planter boxes, and to fill the sidewalk cleaning machines. The cooling tower on the building's roof will be retrofitted to use recycled water in 2015.


Richmond Country Club

EBMUD first supplied recycled water from the West County Wastewater District for irrigation at the Richmond Country Club in 1984. The Richmond Country Club is supplied with recycled water only when available due to other demands on the secondary effluent from the West County Wastewater District.

San Leandro Recycled Water Facility

In 1988, EBMUD constructed the San Leandro Recycled Water Facility to serve recycled water from the City of San Leandro's Water Pollution Control Plant. EBMUD customers currently connected to this recycled water system include two golf courses and the Harbor Bay Parkway in Alameda. Their recycled water use saved more than 125,670,000 gallons of drinking water in FY14.

East Bayshore Recycled Water Project (EBRWP)

In FY14, the East Bayshore Project supplied a total of 55,510,000 gallons to 23 customer sites.

When completed, the East Bayshore Project will supply an annual average of 2.5 million gallons per day (mgd) of recycled water to portions of Alameda, Albany, Berkeley, Emeryville and Oakland.

San Ramon Valley Recycled Water Program (SRVRWP)

The San Ramon Valley project supplied more than 245,370,000 gallons of recycled water to 43 EBMUD customer sites in FY14.

When completed, the San Ramon Valley Recycled Water Program will serve about 2.4 mgd of recycled water to EBMUD irrigation customers in portions of Blackhawk, Danville and San Ramon.
