About Wastewater

The Bureau of Sanitation is responsible for operating and maintaining one of the world’s largest wastewater collection and treatment systems. Over 6,500 miles of sewers serve more than four million residential and business customers in Los Angeles and 29 contracting cities and agencies. These sewers are connected to the City’s four wastewater and water reclamation plants that process an average of 550 million gallons of wastewater each day of the year.

The sewers and treatment systems are continually upgraded to ensure that the health of the public and our environment are protected. To that end, a significant portion of the treated wastewater is used as recycled water and biosolids are reused as fertilizers and soil amendments.

Get details about the wastewater system by exploring the LA Sewers web sites www.LASEWERS.ORG, Sewer System Management Plan (SSMP), and Integrated Resources Plan (IRP).
