City of San Leandro <br />Sewer System Management Plan <br />Volume I <br />P a g e | 5 <br />new to over 70 years old. The oldest sewers are located in the northeastern portion of the City <br />from the Oakland city limits to Castro Street roughly between the Southern Pacific Railroad and <br />MacArthur Boulevard. This portion includes the downtown area and the oldest residential areas <br />of the City. <br />The City maintains roughly two thirds of the sewers within the City limits, primarily serving the <br />northern portion of the City. The remainder of the City is served by the Oro Loma Sanitary <br />District. The sewage from the City sewer system is conveyed to and treated at the San Leandro <br />Water Pollution Control Plant (WPCP). <br />The treatment plant produces high quality secondary effluent at a rate of 4.8 million gallons per <br />day (mgd). An average of 2.5 dry tons of biosolids suitable for recycling are removed from the <br />plant treatment process each day. <br />Section 1 – Goals <br />D.13.(i) Goals: The goal of the SSMP is to provide a plan and schedule to properly manage, operate, and <br />maintain all parts of the sanitary sewer system.
