City of San Leandro Sewer System Management Plan Volume I City of San Leandro Sewer System Management Plan City Service Area and Sewer System The City of San Leandro (the City) is located in Alameda County and is surrounded by the City of Oakland to the north, San Lorenzo and Hayward to the south, San Francisco Bay to the west, with open space preserves and Castro Valley to the east. As of 2007, the City has a population of approximately 86,000 based on estimates from the Metropolitan Transportation Commission and the Association of Bay Area Governments. The City covers approximately 13 square miles with a population density of 6,050 persons per square mile. The City is substantially built out and is currently experiencing an overall decrease in industry over the last five years. The City's sewer system consists of approximately125 miles of pipe, ranging from 6 inches to 42 inches in diameter, and 13 remote lift stations. The sewers in the City system range in age from new to over 70 years old. The oldest sewers are located in the northeastern portion of the City from the Oakland city limits to Castro Street roughly between the Southern Pacific Railroad and MacArthur Boulevard. This portion includes the downtown area and the oldest residential areas of the City. The City maintains roughly two thirds of the sewers within the City limits, primarily serving the northern portion of the City. The remainder of the City is served by the Oro Loma Sanitary District. The sewage from the City sewer system is conveyed to and treated at the San Leandro Water Pollution Control Plant (WPCP). The treatment plant produces high quality secondary effluent at a rate of 6.1 million gallons per day (mgd). An average of 4 dry tons of biosolids suitable for recycling are removed from the plant treatment process each day. Section 1-Goals The goal of this SSMP is to characterize the programs the City has implemented to properly manage, operate, and maintain all parts of the City's sanitary sewer collection system in order to reduce and prevent Sanitary Sewer Overflows (SSOs) as well as mitigate any SSOs that do occur. Accordingly, the SSMP is intended to satisfy the requirements of both SWRCB Order No. 2006-0003, as well as the RWQCB. These Orders are attached as Appendices A and B, respectively. The goals the City has established for itself are to: • Provide a safe work environment for our employees • Eliminate preventable SSOs • Understand the condition of and maintain our infrastructure to maximize the life of the collection system • Operate and maintain our system to minimize impacts on our customers • Be a part of the community and be a responsive public agency • Involve our employees in the strategic planning process for the collection system F'a~e ~9
