2024 Infrastructure Improvement Plan FAQ

To help our customers better understand the Infrastructure Improvement Plan process and our commitment to providing safe, clean, reliable water, we have put together this list of answers to common questions.

Every three years, Cal Water is required to submit an application with the California Public Utilities Commission (CPUC), an independent, third-party, state agency, to review and set our rates so they reflect the actual cost of serving our customers. This process, which takes 18 months or longer, involves a thorough review of operations, finances, and service, along with proposed infrastructure improvement projects across all Cal Water service areas that will enable us to continue providing safe, clean, and reliable drinking water. For more information, please watch the below video.
Cal Water’s rates are set by the CPUC, with input from the public and an independent consumer advocate. The rates reflect the actual cost of operating, maintaining, and upgrading our water system to provide safe, clean, reliable drinking water to our customers. For more information on the rate-setting process, please see the How Rates Are Set page.
We submitted our current Infrastructure Improvement Plan in July 2024, which begins a review and rate-setting process that lasts 18 months or more. New rates from this Infrastructure Improvement Plan will not be effective until 2026 at the earliest.
Rate adjustments are used for necessary infrastructure improvements and modernizations to ensure our customers’ drinking water remains safe, clean, and reliable for their everyday and emergency needs, both now and in the future. This includes completing water quality projects, improving wildfire protection and emergency preparedness, and enhancing water supply reliability and fire protection across our service areas, such as water main replacements, water treatment facility upgrades, and installation of new fire hydrants.

Cal Water is focused not only on providing safe, clean, reliable drinking water to our customers, but also on the affordability of that water. We offer several customer assistance programs to help customers manage their bills. See the calwater.com Customer Assistance page for more information.

We also have a number of water conservation programs in place to help customers save water and money. You can learn more about our conservation programs on the calwater.com Conservation page.
