November 9, 2009 Section 6: Municipal Operations served the citizens, businesses, and industries in the City of San Leandro continuously since 1939. • The WPCP responds to reports of sewer line backups. • Wastewater from homes, businesses, and factories is collected and carried to the treatment plant through 130 miles of sewer lines and 17 remote lift stations. • The WPCP produces a high quality secondary effluent and is designed to treat wastewater at a rate of 7.6 million gallons per day (MGD). The plant is staffed 24 hours, 7 days a week. East Bay Municipal Utility District (EBMUD) sponsors water efficiency programs within the San Leandro community. Water conservation can reduce the amount of wastewater treated in the WPCP, and reduce energy usage related to this City facility, thus leading to greenhouse gas emissions reductions. Available programs include clothes washer rebates, landscape rebates, gray water and irrigation controller programs, as well as free water conservation devices for both the residential and non-residential sectors. The City's effort in developing its recycled water capacities greatly decreases the amount of energy used in transporting water to San Leandro. Recognizing this, in 2008, the City completed a $1.6 million dollar project to use reclaimed water from San Leandro's Water Pollution Control Plant for the majority of irrigation needs at the Marina and Tony Lema golf courses at Monarch Bay. Throughout the system, the City extracts wastewater treated at the WPCP that would otherwise be discharged into the Bay through the East Bay Dischargers Authority pipeline at the San Leandro Marina. The new system saves 98 million gallons a year in City demand for EBMUD water, which equates to roughly the amount 600 households use in a year.22 The reclaimed water system provides roughly 95% of golf course irrigation needs with the remaining 5% (used on the greens) drawn from EBMUD's drinking water sources. The new 22 According to the California Energy Commission's report: California's Water-Energy Relationship (CEC-700-2005- 011-SF), November 2005, reclaimed water can save 1,450 kWh of electricity per million gallons of water reclaimed.
