Westlake Village’s Water: Source, Treatment, and What Remains
By The Clean Water Company
You turn on the tap in Westlake Village, and clean water flows out.
But have you ever wondered where it comes from—or what’s actually in it?
At The Clean Water Company, we’re here to break it down. From sourcing to treatment to what’s still lurking in your water, we help Westlake Village residents take control of what comes into their homes—and their bodies.
Where Does Westlake Village Get Its Water?
Westlake Village relies on the Las Virgenes Municipal Water District (LVMWD), which supplies water to more than 75,000 people across the region, including Agoura Hills, Calabasas, and Hidden Hills.
But LVMWD doesn’t source its own water—it imports it from the Metropolitan Water District of Southern California (MWD). That means the water you use has traveled hundreds of miles from:
The State Water Project (via the California Aqueduct from Northern California)
The Colorado River Aqueduct
Once it arrives, the water is treated locally—often at the Westlake Filtration Plant—to meet legal safety standards. But does “legal” always mean “clean”? Not necessarily.
How Is the Water Treated?
Water treatment includes several key steps:
Sediment removal through coagulation, flocculation, and filtration
Disinfection with chlorine or chloramine to kill bacteria
Routine testing to comply with state and federal standards
While these steps do a lot, they don’t catch everything—especially newer contaminants or the chemical byproducts created during treatment itself.
What Could Be in Your Water?
According to environmental research and public reports, Westlake Village’s water may contain trace amounts of substances you probably don’t want in your glass, including:
Chlorine & Chloramine – Disinfectants that can irritate skin and alter taste
Disinfection Byproducts (THMs, HAAs) – Linked to cancer with long-term exposure
Hard Water Minerals – Cause limescale buildup and reduce appliance efficiency
PFAS ("Forever Chemicals") – Linked to hormonal, immune, and developmental problems
Chromium-6 – A suspected carcinogen
Heavy Metals – Lead and arsenic are especially harmful to children and pregnant women
Nitrates/Nitrites – Can be dangerous for infants and those with certain health conditions
These contaminants can enter your body not just through drinking, but also through bathing, cooking, or even breathing in steam during a hot shower.
What Can You Do About It?
That’s where we come in.

They’re designed to:

Together, these systems give you total peace of mind—everywhere water flows in your home.
The Bottom Line
The water reaching your Westlake Village home may meet basic safety standards, but it’s not always what you’d call “clean.” Legal doesn’t mean optimal—and it’s up to you to go the extra step.
