The Hidden Truth About Hidden Hills Water
By The Clean Water Company
If you live in Hidden Hills, your water travels a long and complex journey before it reaches your faucet. At The Clean Water Company, we help residents understand where their water comes from, what it might contain, and how our advanced filtration systems can protect your health, home, and peace of mind.
Who Provides Hidden Hills’ Water?
Hidden Hills is served by the Las Virgenes Municipal Water District (LVMWD), which supplies water to over 75,000 residents across Hidden Hills, Calabasas, Agoura Hills, and parts of Westlake Village.
Nearly all of LVMWD’s drinking water is imported from the Metropolitan Water District of Southern California (MWD). This water originates from two major sources:
The State Water Project (Northern California via the California Aqueduct)
The Colorado River Aqueduct
After traveling hundreds of miles, the water is processed at local treatment facilities before it reaches your home. But that journey doesn’t guarantee your water is free from concern.
How Is Hidden Hills Water Treated?
Imported water is treated at facilities like the Westlake Filtration Plant, using:
Coagulation, flocculation, and filtration to remove sediments and microorganisms
Disinfection with chlorine or chloramine to kill bacteria and viruses
Ongoing monitoring to meet state and federal drinking water standards
These processes ensure the water is legally safe—but they may not remove all potential threats, particularly newly emerging contaminants or disinfection byproducts.
What Contaminants Are in Hidden Hills Water?
According to public water reports and environmental research organizations like the Environmental Working Group (EWG), Hidden Hills water may contain trace levels of:
Disinfection Byproducts (THMs, HAAs): Linked to increased cancer risk
Chlorine and Chloramine: Known to irritate skin and affect taste/smell
Hard Water Minerals (Calcium, Magnesium): Cause scale buildup in pipes and reduce appliance efficiency
Chromium-6: A suspected carcinogen
PFAS (“Forever Chemicals”): Associated with immune, hormonal, and developmental issues
Heavy Metals (Lead, Arsenic): Especially dangerous to children and pregnant women
Nitrates/Nitrites: Risky for infants and those with compromised health
These contaminants can enter your body through drinking, bathing, cooking, and even inhaling water vapor during showers.
How The Clean Water Company Helps
We specialize in filtration systems built specifically for the water profile of Hidden Hills—providing solutions that go beyond what municipal treatment can achieve.
Whole-Home Water Filtration Systems
Our whole-home filtration systems are installed at your main water line, ensuring that every faucet, shower, and appliance delivers cleaner water.
They help reduce or remove:
Chlorine & Chloramine – Better taste, fewer skin issues
Disinfection Byproducts (THMs, HAAs) – Reduced cancer-linked exposure
PFAS – Fewer long-term health risks from persistent chemicals
Heavy Metals – Including lead, arsenic, and mercury
Hard Water Minerals – Prevent scale and protect appliances *
Pesticides, Herbicides, VOCs – Remove organic pollutants from runoff
*Our salt-free systems restructure hard minerals—like calcium and magnesium—so they don’t bind together or form scale buildup, while allowing these essential minerals to remain in your water.
Enjoy clean, consistent water throughout your home—for everything from showers to laundry to making coffee.
Reverse Osmosis (RO) Drinking Water Systems
Our under-sink RO systems purify water at the molecular level. They're ideal for drinking, cooking, baby formula, and pet hydration.
RO systems:
Remove up to 99% of total dissolved solids (TDS)
Target lead, fluoride, arsenic, PFAS, chromium-6, and more
Provide crisp, clean water from your kitchen tap
When used together, our whole-home and RO systems offer complete home water protection.
