Sewage Treatment

The Long Beach Water Department operates and maintains nearly 765 miles of sanitary sewer lines, safely and expeditiously delivering over 40 million gallons per day to Los Angeles County Sanitation Districts facilities located on the north and south sides of the City of Long Beach. From these facilities, treated sewage will be used in one of three ways. 1) It will be used to irrigate parks, golf courses, cemeteries, and athletic fields, 2) It will be used to recharge our groundwater basin, and 3) It will be pumped into the Pacific Ocean.

Long Beach’s sanitary sewer system carries water from toilets, showers, sinks, and dish and clothes washers away from your home. In fact, most of the water you use in your home is put into the sanitary sewer system. Currently, a majority of the City’s wastewater is delivered to the Joint Water Pollution Control Plant (JWPCP) of the Los Angeles County Sanitation Districts. The remaining portion of the City’s wastewater is delivered to the Long Beach Water Reclamation Plant of the Los Angeles County Sanitation Districts.

JWPCP is located at 24501 S. Figueroa Street, Carson, California. The plant occupies approximately 350 acres to the east of the Harbor (110) Freeway. The JWPCP is the largest of the Los Angeles County Sanitation Districts’ wastewater treatment plants. It provides advanced primary and partial secondary treatment for 350 million gallons of wastewater per day. The plant serves a population of approximately 3.5 million people, including most of the 460,000 residents of the City of Long Beach. At JWPCP, the treated wastewater is disinfected with chlorine and sent to the Pacific Ocean through networks of outfalls that extend two miles off the Palos Verdes Peninsula to a depth of 200 feet.

The Long Beach Water Reclamation Plant is located at 7400 E. Willow Street in Long Beach. The plant occupies 17 acres west of the San Gabriel River (605) Freeway. The plant provides primary, secondary, and tertiary treatment for 25 million gallons of wastewater per day. The plant serves a population of approximately 250,000 people, including a portion of the 460,000 residents of Long Beach. Almost 5 million gallons per day of the purified water is reused at over 40 reuse sites.


LBWD's Sewer System Management Plan (SSMP) 

All Wastewater collection systems in California are required to develop and implement an SSMP.  It is a comprehensive plan which outlines how the agency effectively manages and improves sewer system performance.  It is updated every five years, and the current version covers 2014 – 2019.
