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

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.

Marin Water offers two options for removing an existing lawn and replacing it with low-water use plants. Choose the option that works best for you.

Option 1: Rebate of $1 per square foot of lawn replaced
Customers are reimbursed costs based on receipts submitted for eligible expenses, which include sheet mulching materials, drip irrigation components, and climate-appropriate plants.

Option 2: This option requires a minimum of 500 sq. ft. of turf be converted, but there is no maximum limit. Free sheet mulch material (cardboard, compost, mulch) and delivery, plus a free irrigation conversion kit.

This option provides all the materials necessary to remove your existing lawn using a sheet mulch approach, as well as a component kit to convert existing overhead spray irrigation to high-efficiency drip irrigation.

Projects that have been started or projects that have already been completed prior to receiving approval to participate are not eligible. Contact our water efficiency team at 415.945.1527 for additional information and to apply.

    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.

    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.
