Drought and Conservation

Saving water in a historic drought

Northern California is experiencing an unprecedented drought. While Zone 7 strategically plans for dry years, storing excess reserves in wet years in the local groundwater basin, Kern County storage and recovery programs, and surface water reservoirs, we cannot make it through drought periods without the help of our community. Conservation is an important component to weathering droughts for Californians. Through water conservation and rebate campaigns, we’re working to ensure our community has the resources and information it needs to stretch our limited water supplies.

In March of 2021, Zone 7 requested 10% voluntary water conservation relative to 2020. In July of 2021, Zone 7 increased the voluntary request to 15%, in line with the Governor’s statewide request. In September of 2021, the Zone 7 Board declared a Drought Emergency and called for 15% mandatory conservation relative to 2020.  During FY 2021-2022, demand for treated water decreased by as much as 30% on a monthly basis, averaging 10% in water savings compared to the same time in 2020.

Zone 7  Drought Page

To help the public easily get updates on drought conditions and find information on rebates, water-saving resources and outdoor water use restrictions in their area, we created a drought landing page to host all of these resources at


Zone 7 continued to offer three separate rebates to incentivize water-wise lifestyles. To encourage greater conservation during the drought, Zone 7 increased its rebate amounts for a couple of the rebate programs starting in July 2022. During the 2021-2022 fiscal year, we were able to provide the following water-saving rebates to the Tri-Valley community, a significant increase from the previous year:

222 High-efficiency Clothes Washer rebates

50 Water-Efficient Lawn Conversion rebates

157 Weather-Based Irrigation Controller rebates
