Marin Water is offering Flume Smart Home Water Monitors for just $49, after installation (and shipping and handling) to single-family residential customers. This 67% 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 or by clicking on the chat icon from within the Flume app or Flume website at  

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. 

Residential customers can receive up to $150 for replacing older toilets with new, high-efficiency models. Toilets must be on MaP Testing's PREMIUM list. MaP PREMIUM-rated toilets use 1.1 gallons per flush (GPF) or less, and meet high standards for performance.

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. 

Using a cover when your pool or spa 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 or spa 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.

Open to single-family residential customers only. Limit one per customer. Offer may not be combined with other Marin Water controller incentives.

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. 

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.

    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.

    Marin Water is currently offering customers a limited time offer of a $3 per square foot cash rebate in return for replacing grass in their landscapes. Pre-approval is required to participate in this program; the first step is to submit an application.
