2022 Rates

Understanding water rates can be complicated. We’re here to help and make sure that all rate changes are clearly outlined for our customers. 

The main drivers for rate increases are the cost of water and the cost for infrastructure investment. SJW has three sources of water: local supply from the Santa Cruz Mountains, imported water and groundwater. We purchase the imported water from Valley Water (VW) and pay a groundwater pump tax to VW on the water taken from our wells.

There are two main components to your water bill: service charge and quantity charge. The service charge, based on your meter size, is fixed and does not vary if you use more or less water. The quantity charge is variable and depends on the amount of water you use. You can find the most current water rates on our billing schedules.

Please note that the California Public Utilities Commission approves all rate changes.
