The Atlas · West Hills, Los Angeles County, CA
Water filtration in West Hills.
West Hills sits at the western edge of the LADWP distribution footprint, which means it picks up the same chloramine profile and MWD hardness load as the rest of the north Valley. Homes in this corridor also tend to have larger lot sizes and higher flow rates, so we size the filter system to the actual peak demand of the home rather than a standard residential assumption.
The Water — Where it comes from
The local supply, in plain language.
West Hills is served by Los Angeles Department of Water and Power. LADWP blend serving the western Valley corridor. Same four-source blend as the broader service area: State Water Project, Los Angeles Aqueduct, Colorado River via MWD, and local groundwater wells.
Common local concerns
- · Chloramine disinfection byproducts (TTHM HLRAA 34.4 ppb per LADWP 2024 CCR, MCL 80)
- · HAA5 14.9 ppb (MCL 60)
- · Hardness 6 GPG average for the MWD Jensen supply share
- · Arsenic 3.5 ppb average (MCL 10 ppb)
