GOAL AND INTRODUCTION © 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for San Leandro use only. Page 7 of 57 1.3. Sewer System Asset Overview WDR REQUIREMENTS Att. D-1.3 (pg. D-3) “The Plan Introduction section must provide a description of the Enrollee-owned assets and service area, including but not limited to: • Location, including county(ies); • Service area boundary; • Population and community served; • System size, including total length in miles, length of gravity mainlines, length of pressurized (force) mains, and number of pump stations and siphons; • Structures diverting stormwater to the sewer system; • Data management systems; • Sewer system ownership and operation responsibilities between Enrollee and private entities for upper and lower sewer laterals; • Estimated number or percentage of residential, commercial, and industrial service connections; and • Unique service boundary conditions and challenge(s). Additionally, the Plan Introduction section must provide reference to the Enrollee’s up-to-date map of its sanitary sewer system, as required in section 4.1 (Updated Map of Sanitary Sewer System) of this Attachment.” COMPLIANCE The City of San Leandro is in Alameda County and encompasses approximately 13 square miles. As of 2024, the City had a population of 86,571. 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 City’s wastewater collection system serves approximately 71,000 people in the service area shown in Figure 3, below. The sewer system consists of 122 miles of gravity sewers, 3 miles of force main, 12 lift stations, and 2,383 manholes. Most of the pipelines were constructed from 1940 to 1979 while most of the lift stations were constructed from 1940 to 1959. The City has one siphon and no stormwater diversion structures. The City uses RedZone Robotics’ ICOM3 to manage the collection system preventive maintenance program. The City is actively working on updating ICOM3 to a new RedZone product called Integrity. The City uses ArcGIS for its mapping. There are approximately 19,000 upper and lower service laterals connected to the system. The City owns 19 of these laterals (i.e., on City-owned property). Other than those on City-owned property, the City is not responsible for any of the laterals. The property owner is fully responsible for maintenance and repair of the private sewer laterals. The percentage of residential, commercial, and industrial service connections is shown in Table 2, below. Overall, the City is in a good position to maintain its collection system. It has not identified any unusual challenges other than a portion of the City is served by the Oro Loma Sanitary District collection system.
