Conservation
Conserving water doesn’t mean you have to change your entire lifestyle. By being mindful of what you do around the house, you can save both water and money. The first step towards conserving water is to assess the efficiency of your water usage by taking a free Water Smart Home Survey and learning about money-saving rebates for high-efficiency fixtures and household appliances.
Water Smart Home Survey
North Marin Water District offers customers a free Water Smart Home Survey. This free service is conducted by our friendly, knowledgeable survey technicians and includes both indoor and outdoor water efficiency checks. As part of this program, you will learn how to use water more efficiently and avoid water waste as well as receive money-saving rebates and incentive information to help meet your water efficiency goals. You’ll also be offered free low-flow showerheads and aerators if needed to achieve maximum water efficiency.

Hot Water Recirculation Rebate
North Marin Water District is offering a $100 rebate to customers for self-activated or on-demand hot water recirculation systems only. Timer-controlled and thermostat-controlled systems are not rebated.
A hot water recirculation system is a small water pump that works in conjunction with your hot water heater to more quickly provide hot water to plumbing fixtures (faucets) most distant from the hot water heater. Unheated water left in the plumbing line is recirculated back to the hot water heater as opposed to running down the drain, thereby saving water.
Free Water-Conserving Fixtures Available
NMWD offers free, high-quality shower heads, faucet aerators, and hose nozzles. Customers can pick up free shower heads and faucet aerators at the District office located at 999 Rush Creek Place.
