Residents and businesses are encouraged to participate in Windsor Efficiency PAYS®, an innovative water conservation program that provides:


Immediate Utility Bill Savings

- New Water Saving Fixtures and Landscape Improvements

- No Upfront Costs or Debt

Windsor Efficiency PAYS® is Simple

It allows you to enjoy efficiency upgrades and “pay as you save®”, with no loan and no new debt associated with repayment. After installation of program measures, you start saving on your energy and water bills immediately. You pay a surcharge on your water bill with the following program assurances:
  • Your estimated energy and water savings will exceed the surcharge.
  • If you move or relocate and disclose your PAYS® measures and surcharge, your payment obligation ends.
  • If an installed measure fails during the repayment period and is not repaired, your payment obligation ends.

Windsor Efficiency PAYS® Eligible Upgrades

Certified contractors with the program have been pre-qualified and selected to contact Windsor residents and to install the following upgrade measures:

For Residential Customers:

Basic Package —

Includes the latest in high efficiency showerheads, toilets, and faucet aerators.

Standard Landscaping Package —

Offers drought resistant, Russian River Friendly landscaping.

For Commercial Customers:

Irrigation Retrofit

— Increases irrigation system efficiency by installing Windsor-approved weather-based irrigation control systems (WBIC) and pressure reducing valves, and repairing existing irrigation system leaks and poor-performing spray heads.

To be eligible to install these measures as part of the Windsor Efficiency PAYS® program, participants must show that their current water and energy usage will enable them to achieve sufficient estimated savings from the installed measures.

This program is brought to you by the Town of Windsor with assistance from the Sonoma County Regional Climate Protection Authority and the Bay Area Regional Energy Network (BayREN).
