The City of Manhattan Beach owns and operates a sanitary sewer system.  With a population greater than 10,000, the city is required to comply with the State Water Resources Control Board adopted Order No. 2006-003, Statewide General Waste Discharge Requirements (WDR) for Wastewater Collection agencies in May 2006, which states:
 
“…all federal and state agencies, municipalities, counties, districts, and other public entities, known as “Enrollees”, that own or operate a sanitary sewer system greater than one mile in length that collect and/or convey untreated or partially treated wastewater to a publicly owned treatment facility in the State of California to comply with the terms of this Order.”

Properly designed, operated, and maintained sanitary sewer systems are meant to collect and transport all of the sewage that flows into them to a publicly owned treatment works.  However, occasional unintentional discharges of raw sewage from municipal sanitary sewers occur in almost every system. These types of discharges are called sanitary sewer overflows (SSOs). SSOs have a variety of causes, including but not limited to severe weather, improper system operation and maintenance, and vandalism. The Environmental Protection Agency estimates that there are at least 40,000 SSOs each year throughout the country. The WDR Order is designed to facilitate in reducing the amount of Sanitary Sewer Overflows by outlining steps and actions for Agencies to implement, known as the Sewer System Management Plan.
