General Plan Update - City of Inglewood

3.1 Water System
• Eight emergency connections (two with City of Los Angeles Department of Public
Works, six with Southern California Water Company)
• 14,818 domestic water services, 16 recycled water service connections,
• 198 backflow prevention devices
• 1,540 hydrants, 2,600 gate valves, and 1,250 backflow prevention devices for
internal protection
The City’s service area is divided into three distinct pressure zones because of the
elevation differences. Zone 1 is located at the southernmost part of the city. Zone is
bounded by Imperial Highway to the north, Crenshaw Boulevard to the west, Century
Freeway to the south and Yukon Avenue to the east. Zone 2 is located generally between
Centinela Avenue and Century Boulevard west of Prairie Avenue and includes
Hollywood Park. Zone 3 covers the remaining northern and eastern parts of the City.
According to the City of Inglewood’s database of July 6, 2004, there are 14,505 active
water meters in its water distribution system. The metered accounts are divided into five
water code classifications, as follows: residential (A), commercial (B), Industrial (C),
Municipal (D), and Fire Service (E). Small meters (those sized at two inches or smaller)
account for roughly 96.7 percent of the total, and generate 82.2 percent of the total
revenue, while large meters account only 3.3 percent but generate 17.8 percent of the
revenue. Based on Inglewood’s database for active meters, small meters total 14,032 and
large meters total 226.
The City maintains three pumping stations with a total of 24 separate pumps and three
reservoirs ranging in capacity from 1 million gallons to 16 million gallons of water with an
overall storage capacity of 21.6 million gallons of water.
The City of Inglewood system consists of three closed pressure zones. Normally, the
pressure is maintained by the available pressure at the two imported water connections,
and pumping at the Effluent Pump Station. These pump stations take suction from the
City’s reservoirs, and pump into two closed zones. The two storage reservoirs act as
forebay for the booster pump stations.
Reservoirs
The City has two reservoirs that act as forebay storage for the booster pump stations.
Each reservoir is about 18 feet to 20 feet deep, but the reservoir levels are maintained
below 3.5 feet to ensure circulation and maintain adequate disinfectant residuals in the
system. The North Inglewood Reservoir was constructed in 1974. It is a covered
underground reservoir 144 feet wide and 221 feet long. Its total capacity is 4.6 million
gallons. The reservoir level is currently operated between 1.0 and 3.5 feet. The
Morningside Reservoir was constructed in 1954, and has a total capacity of 16 million
gallons. The reservoir level is currently operated between 0.5 and 2.5 feet.
