Geography 321: Chapter 10: Water in San Fernando

Where do residents of the City of San Fernando get their water

from? The residents get their water from three different water

sources. The first source is “Local groundwater wells that draw

water from the Sylmar Basin.” Water is also imported from the

Metropolitan Water District. In extreme emergencies, water also

comes from a connection from the City of Los Angeles distribution

system. 98 percent of the water that was used in San Fernando in

2010, come from the local groundwater wells, and 2 percent was

purchased from the Metropolitan Water District.

To purify and treat the water, groundwater is taken from the Sylmar

Basin and chlorine is added in a sodium hypochlorite solution

(0.8%) used to disinfect the water. The process is monitored on a

daily basis. The water is then pumped into reservoirs, and thanks to

gravity it is distributed to homes and businesses in San Fernando.
