Marin Water offers a great package of rebates and money-saving incentives for water conservation. Saving water isn’t just about saving money. It’s about managing our resources and building a more sustainable future. Check out our rebates designed to make saving water a little easier. 

Replacing your older clothes washer with a new high-efficiency model is an easy way to save money and conserve water. You may qualify for a rebate of up to $100.

We are now offering Flume Smart Home Water Monitors for just $50, after installation, to single-family residential customers. This 75% discount is made possible through a partnership with Flume Water and the California Water Efficiency Partnership.  

The Flume device is easy to install and attaches to your existing water meter. Through a WiFi connection, the Smart Home Water Monitor gives customers information about their water use, potential leaks, and incidences of high water use in real-time. Leak notifications can be sent directly to your smartphone. With Flume, you can learn more about how you use water at home and so you find ways to use less.

Click on the button below to redeem this offer. Simply enter your Marin Water Customer Number (located in the upper right-hand corner of your water bill) when prompted. You will purchase and receive your discounted device directly from Flume. For additional information, please contact Flume by email at Support@FlumeWater.com or by clicking on the chat icon from within the Flume app or Flume website at FlumeWater.com/Marin.  

Open to single-family residential customers only. Limit one per customer. Most, but not all, water meters are compatible with Flume devices. Services with non-compatible meters, including ones where Automated Metering Infrastructure (AMI) is already installed, are not eligible for this offer.

When you install a kit to divert water from your washing machine to your garden, it’s called a Laundry-to-Landscape graywater system. We have partnered with the Urban Farmer Store to offer a $100 discount on your purchase of a laundry-to-landscape graywater kit. Please fill out the Laundry-to-Landscape Graywater Program Application to apply.

Interested in learning more? Attend the upcoming graywater workshop on June 9.

Please visit the Greywater Action website to view previously recorded workshops and view additional resources. 

To reduce water waste while you wait for the water to warm up, we recommend installing a hot water recirculating system. The district offers a $50 rebate to help offset the cost of the system. Read the program details and apply for your rebate today. 

Marin Water is offering customers a cash rebate in return for replacing grass in their landscapes and, as a result, reducing the need for irrigation.

Until October 31, 2021, Marin Water is offering $3 per square foot of existing grass removed using a sheet mulch approach, and for disabling the irrigation system in the project area.

Preapproval is required to participate in this program. Applications will be provided to customers only after the site has been approved through a site inspection.

Review the Cash for Grass - Lawn Replacement Rebate Information prior to scheduling the pre-approval inspection.

  • Rebates cannot be applied retroactively. Projects that have already started, or projects that have been completed are not eligible for the rebate.
  • Lawn converted to artificial turn, non-permeable hardscape, pool or other water feature does not qualify for this rebate.

To schedule a pre-approval site inspection, email the Water Efficiency team at Conservation@MarinWater.org. Please include your name, address, customer number and phone number in the email. 

Using a cover when your pool is not in use is the best way to reduce evaporation and save water. Marin Water is offering a rebate of up to $100 for customers that purchase and install pool covers. Read the program details, and apply for your rebate today. 

We have partnered with Rachio and the California Water Efficiency Partnership (CalWEP) to offer Marin Water's customers a significant discount, up to 70%, on Rachio 3 controllers. With mobile app-based control and premium Weather Intelligence™ Plus, the Rachio 3 accurately predicts weather changes and automatically adjusts your watering schedule so your landscaping always receives just the right amount of water.

    Rainwater harvesting is the practice of collecting rainwater from rooftops and storing it for later use. This practice can reduce potable water use while also helping to limit erosion and polluted runoff that harm our creeks. Just one inch of rain on a 1,000 square-foot roof produces 600 gallons of runoff. Rainwater harvesting systems and roof gutters should be cleaned seasonally.

    Marin Water offers up to 50 cents per gallon of storage, not to exceed actual cost. Total rebates for rain barrels and cisterns may not exceed $1,000 per site.

    Remember that harvested rainwater, whether from a rain barrel or a cistern, should not be used for drinking or for human consumption. It should be used for irrigation purposes only.

    Let us do the work! Apply for our free sheet "Mulch Madness" free sheet mulching program and we'll deliver and install the materials, and cap your sprinklers. 

    You can combine rebates from Pacific Gas and Electric and the Sonoma-Marin Saving Water Partnership to cover the full cost of the equipment when you purchase and replace existing qualifying commercial kitchen equipment like dishwashers, steam cookers, pre-rinse spray valves and lavatory faucets.

    For more information, visit the Sonoma-Marin Saving Water Partnership website. 

    WaterSense labeled irrigation controllers act like a thermostat for your sprinkler system: telling it when to turn on and off based on local weather and landscape conditions. With proper installation, programming, and maintenance, these self-adjusting controllers can reduce overwatering. Install a WaterSense labeled irrigation controller and receive a rebate up to $100. Note: Rachio 3 irrigation controllers are also available at a discount, up to 70%, through a partnership program with Rachio. Customers may apply for only one controller incentive, not both.
