The Atlas · Calabasas, Los Angeles County, CA

Water filtration in Calabasas.

Calabasas and Agoura Hills run on Las Virgenes MWD water, which is a different utility than LADWP and a different disinfection profile. The water arrives at the meter already filtered, but the hardness and total dissolved solids inherited from Colorado River blending are exactly the load a properly specced descaler and whole-home filter is designed to manage.

The Water — Where it comes from

The local supply, in plain language.

Calabasas is served by Las Virgenes Municipal Water District. Imported water from Metropolitan Water District of Southern California, primarily State Water Project deliveries from Northern California with seasonal Colorado River blending. Treated at the Joseph Jensen Filtration Plant before distribution.

Common local concerns

  • · Hardness from State Water Project and Colorado River imports
  • · Total dissolved solids elevated by Colorado River blending
  • · Chlorine disinfection residual
