Conservation Rebates Daily Water Saving Tips, Fix Leaks - Saves 110 Gallons per Month

The Department of Water Resources (DWR) has a rebate program that provides a rebate for removing turf grass at California single-family residences. The turf rebate program is financed by the Proposition 1 water bond approved by voters in 2014. The program will help further reduce water use in homes by replacing more than 10 million square-feet of lawn. DWR will oversee the rebate program, that provides up to $2 per square foot for lawn replacement. Californians can visit the Save Our Water Rebates website to apply for the rebate.

Toilet Rebates

  • 2018: $100 Rebate through December 31, 2018 to residents and businesses in the Berryessa Watershed. Funded in part by grant funds from the California Department of Water Resources.

Older toilets may use up to 40% of your indoor water budget. If your residence contains toilets purchased before 1992, you may be using anywhere from 3.5 to 7 gallons with each flush. Today's High-Efficiency Toilets (HETs) do the job using just 1.28 gallons or less. Napa County is offering a $100 rebate to replace up to two toilets installed before 1992 with new WaterSense labelled HETs. To apply for a rebate, review the application (PDF) and then contact Deborah Elliott by email or at (707)259-5969 to be sure that you are eligible.

Clothes Washer Rebates

  • 2018: $100 Rebate through December 31, 2018 to residents in unincorporated Napa County

The clothes washer is typically the second largest water user inside the home, after toilets. While traditional washers may use more than 40 gallons of water per load, new high-efficiency models use less than 18 gallons, saving more than 50% in water and energy costs. High-efficiency washers also require less detergent, are gentler on your clothes, and result in shorter drying times. The U.S. EPA's Energy Star Program certifies clothes washers to assist consumers, and has developed new criteria to label exceptional products as Energy Star Most Efficient.

Through December 31, 2018, Napa County is participating in the Bay Area Residential High-Efficiency Clothes Washer Rebate Program to offer a rebate on certain high-efficiency models. For 2018 purchases made through December 31, models meeting Energy Star Most Efficient criteria (PDF) qualify for a $100 rebate.

In September 2009, the Napa County Board of Supervisors authorized County staff to begin outreach on a water conservation program in the unincorporated county, specifically targeting the Milliken-Sarco-Tulocay (MST) area. County staff, with input from the agricultural community, the Napa County Resource Conservation District, and the California Department of Fish and Game have come up with some opportunities to help residents, growers, and winery owners alike conserve water.
