Water RateShare Discount

The City of Napa offers a water bill discount to assist customers who may be struggling to meet their basic needs. Adopted by City Council on April 17, 2012, the Water RateShare Program is only available to low-income single-family residential customers who are already enrolled in the PG&E California Alternate Rates for Energy (CARE) Program for their energy bill. To comply with Prop 218, funds for this assistance program are limited as they cannot be drawn from water rate revenue.

Effective with billing periods beginning on or after December 1, 2017, the Water RateShare Discount is now:

$25.00 per bimonthly water bill


  • City of Napa Water Account Type must be Single-Family Residential (Inside City or Outside City).
  • Customer must be currently enrolled in the PG&E CARE Program for energy bill discounts.

Enrollment in Water RateShare is on a first-come first-served basis, but signing up is easy!

How to Sign Up
