3.2 SEWER AND WASTEWATER
This section describes the existing sewer and wastewater system in the City of Inglewood.

City’s 2005 Urban Water Management Plan and discussions with service providers—
Inglewood, and Los Angeles County Sanitation District.
• Existing Conditions
Service Providers
Most cities have complex systems of sewer lines feeding into larger lines to move raw
sewage to a regional treatment facility. Some cities also have agreements for treatment
with other local providers. Sewer and wastewater service within the City of Inglewood is
provided by the City and the Los Angeles County Sanitation District (LACSD). Similar to
the boundaries of the City’s potable water system, LACSD provides sewer service for the
entire City, a service area of approximately 8.9 gross square miles, as illustrated in
Figure 3.2-1.
LACSD boundaries encompass nearly 85,019 acres, and contains 155 miles of sewer
mains in the City of Inglewood, including 3,240 sewer manholes and 16,393 sewer lateral
connections. LACSD has a total of 16,177 active refuse accounts in the City.
Wastewater Collection and Treatment
The Los Angeles County Sanitation District (LACSD) manages wastewater collection and
treatment for the City of Inglewood. The wastewater from the City primarily flows to the
Joint Water Pollution Control Plant (advanced primary with partial secondary treatment)
located in the City of Carson. The wastewater flow from the City to the LACSD
treatment facility estimated at 10.6 million gallons per day (mgd), of which approximately
8.9 mgd is from the portion of the City served by the City’s water system. 28 LACSD is
also responsible for monitoring industrial waste discharges into the wastewater system.
Joint Water Pollution Control Plant
The Joint Water Pollution Control Plant (JWPCP) is located at 24501 S. Figueroa Street
in Carson, California. The plant occupies approximately 350 acres to the east of the
Harbor (110) Freeway. One hundred thirty five of the 350 acres are used as buffer areas
between the operational areas and surrounding residential neighbors. These buffer areas
include nursery operations, the Wilmington Boys and Girls Club, a fresh water marsh area
and Kellogg’s Supply Inc.
