  1. A Water-Wise Consultation: A Sonoma Water staff member can support you with an irrigation assessment to make sure your irrigation system is running properly. We can also review historic water usage records and explain your water bill. We can check fixtures to evaluate the flow rates, and provide you with a report on water use findings and make recommendations to improve water use efficiency. To schedule your Water-Wise Consultation contact Kris Loomis at or call (707) 524-1165.
  2. Become a Certified Green Business: The County of Sonoma Energy and Sustainability Division provide no-cost water and energy audits to assess your business practices and support you with achieving certification. To become a Certified Green Business, contact Energy and Sustainability at or (707) 565-6470 . For more information:
  3. Know your flow rates: Contact your local water service provider for a flow rate bag. Hold the bag under the faucet and turn the water on full volume for five seconds. After five seconds, turn the water off and read the rate on the bag.
  4. Test toilets for leaks: If you have a tank-type toilet, toilet dye tablets are available from your local utility office or you can use food coloring. To perform a leak test, place a dye tablet (or a few drops of food coloring) in the tank of your toilet. Do not flush. Wait 15 minutes, then check the bowl of the toilet. If the water turns color you have a leak. Consult with a licensed plumber if you have flushometer valve toilets.
  5. Invest in efficiency upgrades: Especially for older, high water use toilets and urinals which have a short payback period from water and sewer bill savings.

Minimize TurfFor planter strips or areas of turf 10' wide or less, replace with native plants that require less water. Adding mulch to your landscape will help to shade the soil and reduce water lost to evaporation. Rebates may be available at Sonoma-Marin Saving Water Partnership
