How Rates Are Set
Understanding the Infrastructure Improvement Plan and rate review process
Cal Water’s rates are set by an independent, third party, state agency—the California Public Utilities Commission (CPUC)—with input from the public. We are required to file a new application every three years, so that rates reflect the actual cost of operating, maintaining, and upgrading our water system to provide safe, clean, reliable drinking water to our customers.
Any changes to customer bills as a result of this Infrastructure Improvement Plan would not occur until January 2026 at the earliest.
