Every three years, Cal Water submits an Infrastructure Improvement Plan to an independent state agency and separate state watchdog, the Office of Ratepayer Advocates, for review and approval. This process helps to ensure that we are able to continue providing a reliable supply of high-quality water for customers’ everyday needs and sufficient resources for firefighters.

Our most recent Infrastructure Improvement Plan for years 2019-2021 was submitted on July 2, 2018, kicking off an 18-month review process. Final implementation is expected no sooner than January 2020, including revised budgets that reflect the actual cost of operating, maintaining, and upgrading our water system.
