Windsor Efficiency PAYS

Windsor Efficiency PAYS logo

Windsor Efficiency PAYS® provides water and energy saving upgrades for Windsor residential properties that provide immediate utility bill savings, new water/energy saving appliances, and drought-resistant landscaping — with no upfront cost or debt.

Windsor homeowners and renters can “pay as you save®” by installing:

  • Low-flow showerheads and aerators
  • High efficiency measures — toilets, CFLs, clothes washers/dryers, refrigerators, and hot water recirculation pumps
  • Drought-resistant landscaping — This is the single most important action you can take to improve the water supply

PAYS® upgrade measures are available to eligible Windsor residents based on current water and energy usage. Our Certified Contractor will help determine if a customer meets eligibility. Upon installation of selected efficiency appliances or landscape, you pay a surcharge on your water bill with the assurance that estimated savings on your combined utility bill (energy/water) will exceed the bi-monthly surcharge.

Additional customer assurances include:

  • Certified contractors who have been pre-qualified to install upgrade measures, comply fully with installation standards/codes, and are fully insured and bonded.
  • Ability to end payment obligation if the customer leaves the home or apartment in which they have installed PAYS® measures that will remain installed at the residence.
  • Ability to end payment obligation if any installed measure fails at any time and cannot be repaired.

Windsor Efficiency PAYS® is a program of the Town of Windsor in partnership with Sonoma County Energy Independence Program, Sonoma County Regional Climate Protection Authority, Sonoma County Water Agency, and Climate Protection Campaign.
