Lawns typically need four times more water than climate appropriate shrubs and perennials, which makes converting lawns to sustainable landscapes one of the best ways to use water more efficiently. 

Marin Water offers customers a rebate of up to $3 per square foot for replacing grass in their landscapes. Application and pre-approval is required. Homeowner reimbursements will be capped at 1,000 square feet, and business owners capped at 5,000 square feet.

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. 

Marin Water offers up to 75 cents per gallon of storage, not to exceed actual cost. The rebate is for new rain barrel installations only and cannot exceed system cost.
