The agency serves a population of 330,920 people and is responsible for maintaining 390 miles of sewer main, 8,000 sewer manholes two sewage lift stations, and two force mains. The majority of the City's sewer mains range from 6" - 12" In diameter, with several as large as 21" in diameter, the majority of which is proactively cleaned on an annual basis. Additionally, the City provides customer service, identifies illegal connections to the sewer system, and sewer blockages. The City is not responsible for maintaining the 46,000 private sewer laterals. However, the City does perform repairs for sewer laterals within public right of way. The City has established and implemented the necessary programs to maintain all aspects of their sewer system in good working order and to reduce the number and severity of sanitary sewer overflows (SSOs). The City monitors the effectiveness of these programs throughout the year and makes the necessary modifications to correct any deficiencies. The City has established sufficient sewer designs, regularly evaluates the condition and capacity of its sewer system, and has implemented an effective FOG Control Program. Additionally, the City has identified problematic sewer mains, which are cleaned on a more frequent basis (enhanced maintenance locations). In addition to proactive and preventive maintenance practices, the City also identifies areas of the sewer system in need of repair and /or replacement and prioritizes corrective measures for these area based on asset risk and resource factors. The staff supporting the operation and maintenance of the sewer system has undergone training to perform such activities and continue development of their skills through participation in external and internal training opportunities. The elements and provisions established in the City's Sewer System Management Plan (SSMP) are based on the requirements established in the State Water Resources Control Board's Order No. 2006- 0003 -DWQ. All federal and state agencies, municipalities, counties, districts, and other public entities that own and operate sanitary sewer systems greater than one mine in length that collect and /or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California, are required to comply with the terms established in this order. The City's SSMP and maintenance and management program complies with this established order, and also provides the necessary measures to reduce and prevent SSOs as well as mitigate the effects of the SSOs that do occur. As stated in the State Water Resources Control Board's Order No. 2006 - 0003 -DWQ, the City must meet the following fifteen (15) provisions: 1.
