Water Cost of Service Rate Study

The City of Napa proposed a rate increase to water service charges for all customer classes, as detailed in Proposed Rate Sheets (PDF). The 2023 Water Cost of Service Rate Study (PDF) demonstrated the need to adjust rates for all customer classes to ensure stability of the water system. The structure of the rates will remain the same as they have been since 2017.  The Water RateShare discount for eligible low-income customers would be maintained at $25 per bimonthly bill.Cost of Service Study-Cover Opens in new window

Previous Rates 2017-2023

The Water rate schedule included five years of fixed rate increases, but was followed by no increase from late 2022 through 2023. During those last two years the rates did not recover the actual cost to provide water service, and the rates needed to be adjusted to reflect water system costs that have continued to rise including the recent inflationary period.
