Water Conservation

SEASONAL REMINDER:  The winter rains have arrived and automated irrigation systems should be off for the duration of the rainy season. Making sure irrigation systems are off from December through March is especially important since these months are used to determine residential sewer rates. Your winter monthly-average water use, or "sewer cap", is used as the multiplier for the wastewater treatment portion of your Windsor utility bill (sewer cap x $cost/gal of treatment). The lower your winter water use, the lower your sewer bill will be.  Water conservation.  It's a year-round habit, for life.

Water Smart Home Program 
 Winter is a great time to sign up for a free home water assessment to determine if your home is water efficient and leak free. Our team will check both indoor water fixtures and outdoor irrigation systems and provide a report with recommendations for efficiency improvements. Knowing your house is leak free will put your mind and pocketbook at ease. To schedule an appointment, fill out and submit the online sign-up form or call (707) 547-1909.

Making Water Conservation a Windsor Way of Life

The recent drought has served to reinforce our understanding that efficient water use and elimination of wasteful practices needs to become a commonplace living style in California.  To that end, the state has taken steps to extend the statewide water-waste prohibitions put into effect during the drought until they can be adopted as permanent.  These prohibitions will be undergoing a public process to further define and adopt them as statewide law, to be enforced in dry years and wet.  Although these prohibitions may be new to many locations in the state, Windsor has had enforceable prohibitions on water waste in effect for over 20 years.

We are confident that everyone in Windsor will continue to make it a priority to use water wisely, and will maintain the momentum the drought provided to continue to upgrade fixtures and landscapes to lower water-use alternatives.  Thank you for your collective actions to reduce water use, and just as importantly, for recognizing the need to make efficient water use and conservation a part of everyday life in Windsor.

Statewide Prohibitions on Water Waste:
  • Use of a hose for washing sidewalks, walkways, driveways, parking lots and other hard-surfaced areas*
  • Washing a car, boat, trailer, or other equipment with a hose not equipped with a shut-off nozzle
  • Watering landscapes in a manner that causes runoff
  • Watering landscapes during or within 48 hours following rainfall
  • Using non-recirculated water in a fountain or other decorative water feature
*The Town’s local water waste code includes a provision allowing a variance for pressure washing of hard surface areas to address health and public safety concerns, such as might be encountered as a slip and fall hazard in front of a food establishment, or to address health & sanitation needs within defined trash enclosures.  This practice is allowable only when done appropriately and in consideration of other Town code requirements, such as the non-stormwater runoff restrictions to storm drains.  For questions or clarification related to pressure washing, please call (707) 838-5357 during regular business hours.


The Town of Windsor’s Water Conservation Program provides residents and businesses with in-depth services, education, and guidance about how to manage water wisely.

We are committed to partnering with our citizenry and with other local government and non-governmental organizations to identify where improvements to water efficiency can be made in order to ensure an ample, long-term supply for the Town.

We hope that you will join with us in this commitment to conserve and use water efficiently, and that you will find the following water conservation programs, information, and links useful:
