The City’s water distribution system consists of 43 miles of water mains, ranging from 2 inches to 16 inches in diameter. The large majority (70%) of the City’s water distribution pipes were installed between 1928 and 1940. The distribution system also includes 797 water valves, 470 fire hydrants, and 55 flushing points.

The City is investing in significant updates to the water production and distribution systems. The roadmap for these upgrades has been outlined in the City’s Water Master Plan, a dynamic document that prioritizes recommended improvements to the water system. The most recent Master Plan update was done in 2015, and is available here.

Key components of the water system are:

  • Water is supplied by (2) West Basin Municipal Water District imported water connections and by the Cypress Water Production Facility (CWPF)
  • (1) Groundwater well, Well No. 5, located at the CWPF
  • (2) Pressure-reducing stations used to control pressure within (4) individual water pressure zones
  • (1) Booster pump station
  • (2) Reservoirs, (1) 5.3-million-gallon concrete reinforced reservoir at the CWPF and (1) 100,000-gallon elevated steel tank located above the Harbor Hills Housing Authority complex
  • (3) Emergency interconnections, (2) with the City of Torrance and the other with Los Angeles Department of Water and Power (LADWP)
