Cal Water’s Westlake District
Serving a portion of Thousand Oaks
Cal Water’s Westlake District was formed in 1983 with the purchase of the Westlake Water Company. To meet the needs of our customers, we purchase imported surface water from the Metropolitan Water District of Southern California (MWD) through Calleguas Municipal Water District. Our system includes 105 miles of pipeline, six storage tanks, and 23 booster pumps. We proactively maintain and upgrade our facilities to ensure a reliable, high-quality supply.
Frequently Asked Questions
What forms of payment does Cal Water accept?
You can pay your Cal Water bill with cash, a check, a money order, a credit card, a debit card, or bank account. However, available payment options vary depending on the payment location or method. For more detail, see the Payment Options page.
What is the Customer Assistance Program (CAP)?
Cal Water offers a Customer Assistance Program (CAP — formerly LIRA) to customers who meet income guidelines. Qualifying customers receive a discount on their monthly service charge. You can visit the CAP page to see if you qualify and download an application form. If you live in a single-family residence, you can also apply online.
What should I do if my bill seems higher than usual?
See the High Bills page for more information and suggestions.
How do I turn off the water supply to my house in the event of a break in my plumbing or a repair?
You can interrupt the flow of water to your home by turning off your house valve. House valves are usually located beneath a faucet outside the home, most typically near the faucet for the garden hose. If you cannot find your house valve, please contact your local Customer Center for assistance.
