Source of Supply

West Valley Water District obtains water from both local and imported sources to serve its customers.

Local Water 


51% – Over half of the District’s water supply is from its own groundwater wells, located in five local basins:

  • Chino Basin
  • Bunker Hill Basin
  • Lytle Creek Basin
  • North Riverside Basin
  • Rialto-Colton Basin

17% – Additional groundwater is purchased from San Bernardino Valley Municipal Water District through the Base Line Feeder Project. This water also comes from local wells in the Bunker Hill Basin.

Surface Water

18% – The District obtains a portion of its surface water from Lytle Creek in the San Bernardino Mountains. This water is treated through the District’s Oliver P. Roemer Water Filtration Facility.

Imported Water

State Water Project

14% – The District also purchases surface water from the State Water Project through San Bernardino Valley Municipal Water District. This water is also treated through the District’s Oliver P. Roemer Water Filtration Facility.

How Safe Is Our Water?

We’re vigilant when it comes to safeguarding our water supplies. Our water meets all Federal and State Regulations. We’re proud to report that our District always meets, and exceeds, these standards.

Entrained Air

If your tap water seems cloudy, hazy, or has a slightly “milky” appearance, you’re probably experiencing a condition known as “entrained air.” This condition is harmless and is almost always caused by air in the water. One of the many properties of water is its ability to dissolve gases—including air. Sometimes the air comes back out of the water in the form of many tiny bubbles, giving the water a “milky” appearance.

If your tap water is “milky” and you want to confirm whether or not you are experiencing entrained air, rinse out a clear glass twice and then fill it with cold tap water. After a few moments, the water should begin to clear from the bottom of the glass to the top as the bubbles rise to the surface. This is a completely natural occurrence and is harmless. If the water in the glass does not clear after five minutes, please call our office and we’ll be happy to assist you.

School Lead Testing Program


On October 13, 2017, California Assembly Bill 746 (AB 746) was signed into law. AB 746 requires all community water systems, such as West Valley Water District (WVWD), to test the lead levels of drinking water for all public—K-12 schools, preschools, and child day care facilities located on public school property by July 1, 2019.

Private schools (K-12) are not required to have their portable water systems tested for lead under AB 746. However, private schools are still eligible to request testing—requests must be made by November 1, 2019.

Sampling Request

Schools interested in lead sampling are encouraged to submit a written request to WVWD’s Water Quality Department. Please email the requests to abudicin@wvwd.org. WVWD will cover the costs of the initial lead sampling.

Lead Sampling in Schools – 2017 Results

WVWD worked with 10 schools during 2017 in a collaborative effort to proactively test for lead within school facilities. All school samples analyzed for lead were below the action level of 15 parts per billion.

Importance of Lead Testing in Schools

Lead rarely occurs naturally in WVWD’s drinking water, but may become present when water passes through older plumbing fixtures or from solder containing lead that is used to connect plumbing fixtures. The presence of lead in levels above the action level of 15 parts per billion can cause serious health problems, especially for pregnant women and children.

WVWD is committed to providing high quality drinking water to all schools within its service area and provides safe drinking water that meets all state and federal requirements to all of its customers. Additional information on lead sampling for schools can be viewed at the California Water Boards Department of Drinking Water website. If you have any questions regarding lead sampling for schools within WVWD’s service area please contact WVWD’s Water Quality Supervisor.
