Water Treatment

Function
Providing the highest quality of water for its customers is a vital component of Cucamonga Valley Water District's (CVWD) mission. Surface water and imported water are treated at one of the three treatment facilities operated by the district. After the water has gone through the filtration process the water is disinfected with chlorine.

Groundwater
Groundwater does not require the same treatment process as surface water since it goes through a natural filtration process as it percolates into the ground. When the ground water is extracted it is disinfected before it enters the distribution system.
