Current Recycled Water Users
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.
Industrial
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. Using about 3.8 mgd of recycled water in Chevron's cooling towers currently saves enough drinking water to serve the average indoor and outdoor needs of an estimated range of 18,500 to 25,000 EBMUD residents everyday.
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.
The Chevron Richmond Refinery uses a total of about 11 million gallons of water each day. 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 water needs of more than half the residents of the City of Richmond.

Oakland has been irrigating Mandela Parkway with recycled water since 2008
EBMUD Use
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. About 2.3 mgd were recycled at our WWTP in 2011. 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-level planter boxes (pending a proposed improvement project), and to fill the sidewalk cleaning machines.
Irrigation
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.
Village Green Park in San Ramon began using recycled water in 2006
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 served by EBMUD's San Leandro facilities include two golf courses and the Harbor Bay Parkway in Alameda. Their recycled water use saved more than 57,000,000 gallons of drinking water in 2011.
East Bayshore Recycled Water Project (EBRWP)
In 2011, the East Bayshore Project supplied a total of almost 29,000,000 gallons to 16 customer sites.
When completed, the East Bayshore Project will supply an annual average of 2.2 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 almost 192,000,000 gallons of recycled water to 36 EBMUD customer sites in 2011.
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.
