Sanitation Water Efficiency Rebate Program

Save Water. Save Money.

The Sonoma County Sanitation Water Efficiency Rebate Program was established to help you save water, save money, and reduce wastewater flows to your local wastewater treatment plant.

This program is available for the following sanitation districts and zones:

  • Airport / Larkfield / Wikiup Sanitation Zone
  • Geyserville Sanitation Zone
  • Occidental County Sanitation District
  • Penngrove Sanitation Zone

Rebates available on a first come, first served basis through June 30, 2024 while funding lasts. All rebates must be submitted with a completed IRS Form W-9 for income tax reporting purposes. A 1099-MISC form may be issued if combined rebate incentives from the County of Sonoma total $600 or more per tax year. Download the W-9 form at Rebate programs subject to change without prior notice.

Front Load High-Efficiency Clothes Washer Rebate

Get up to $125* back on the purchase and installation of a new, qualifying front load high-efficiency clothes washer (HEW). A new washer can use 40 to 60% less water and energy than older, top loading clothes washers. HEWs use 18 to 25 gallons of water per load compared to 50 or more gallons for older top loading models. Use less water, less energy, and less detergent while cleaning your clothes better and with less wear and tear. New HEWs also remove more water from laundry during the spin cycle so loads spend less time in the dryer. The savings all add up to a great deal that can pay for itself in a few years. For a listing of qualifying clothes washers, visit the Consortium for Energy Efficiency website. Rebates are available for all front load clothes washers listed as “Tier 2" and "Advanced Tier". Top load models and models of any type with silver ion technology are not eligible.

Please note Sonoma Valley County Sanitation District customers are not eligible for this program. Water customers of the City of Sonoma and Valley of the Moon Water District may be eligible to participate in the Sonoma-Marin Saving Water Partnership High-Efficiency Clothes Washer Rebate Program.

High-Efficiency Toilet Rebate

Get up to $150* back on the purchase and installation of each qualifying 0.8 gallon per flush (gpf) or less high-efficiency toilet (HET). Replacing your older toilet saves water and reduces wastewater without sacrificing performance.  For complete details and list of eligible toilet models, please see the rebate application form or call (707) 547-1918.
