Once at the plant, wastewater is treated and dechlorinated. Most of the effluent is discharged to San Francisco Bay through an outfall pipe shared by other communities in Alameda County. Some of the effluent is directed to a recycled water system owned by EBMUD and is used to irrigate golf courses in Oakland and Alameda. Sludge from the treatment plant is used as an agricultural soil conditioner. The treatment system is enhanced by an aggressive industrial waste pre-treatment program serving industrial customers. The City is in the process of undertaking significant capital improvements to the wastewater system, including the replacement of undersized pipes beneath the I- 880 Freeway. Future improvements could include the expansion of the recycled water system to serve the City’s Monarch Bay Golf Course. Administrative changes, including the possible transfer of wastewater services to EBMUD or another agency, also have been discussed as a means of achieving greater economies of scale and adding wet-weather capacity to the treatment system. 4.4.2.2 Oro Loma Sanitary District The Oro Loma Sanitary District was formed in 1911 and today provides wastewater collection and treatment services, garbage collection, and recycling services for the 44,000 customers within its 13 square mile service area. Approximately 20 percent of the District’s customers are located within the city of San Leandro. Oro Loma treats approximately 15 million gallons of sewage per day, including flow from the Castro Valley Sanitary District. The District’s treatment plant is located at the end of Grant Avenue in San Lorenzo, just south of the San Leandro city limits. As at the San Leandro plant, wastewater is treated to a secondary level through an activated sludge process. Treated effluent is disposed to the deep waters of San Francisco Bay through the collectively owned East Bay Dischargers Authority pipeline. An average of 230,000 gallons a day of treated effluent is reused for irrigation on the Skywest Golf Course in Hayward. The District has a Renewal & Replacement and Capital spending program which covers ongoing repair and replacement of system components. Revenues for this program are generated through sewer connection fees and user fees. 4.4.3 Drainage The City of San Leandro Department of Public Works owns and maintains 175 miles of storm drainage conduits. The City’s storm drain system feeds into a larger system owned and operated by the Alameda County Flood Control and Water Conservation District (ACFCWCD). This system includes the lower reaches of San Leandro and San Lorenzo Creeks, as well as a number of channels extending into San Leandro neighborhoods west of I-880. The District’s drainage facilities include levees, pump stations, erosion control devices, and culverts.
