Free Laundry-to-Landscape Graywater Workshops

Marin Water is partnering with the Urban Farmer Store of Mill Valley to offer two free webinar workshops to learn about the design, installation, and maintenance of a residential laundry-to-landscape graywater system.

Laura Allen, a founding member of Greywater Action, will lead the workshops. Laura has spent the past 20 years exploring low-tech, urban, sustainable water solutions. She is the lead author of the San Francisco Graywater Design Guidelines for Outdoor Irrigation, and authored The Water-Wise Home: How to Conserve and Reuse Water in Your Home and Landscape and Greywater, Green Landscape.

Laundry-to-Landscape Graywater Program

A graywater system efficiently channels and deposits water to the plants and root systems that need it most. It saves water and saves money. We have partnered with the Urban Farmer Store to offer eligible participants a $100 discount off the purchase of a laundry-to-landscape graywater kit (retail cost of $175) when they attend one of the free workshops above. The graywater kit includes the basic components necessary to divert clothes washer water to the garden. The offer also includes a loaner tool kit with the tools necessary for DIY installation. Please fill out the Laundry-to-Landscape Graywater Program Application to apply.

WaterSense Smart Irrigation Controller Rebate

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 by more closely matching irrigation timing to plant water needs. Install a WaterSense labeled irrigation controller at your residential or business property and receive a rebate up to $100.

Rain Barrel and Cistern Rebate Program

Up to $0.50 per gallon of storage, not to exceed actual cost. Total rebates for rain barrels and cisterns may not exceed $1,000 per site.

Rainwater harvesting is the practice of collecting rainwater from rooftops and storing it for later use. Most people use rainwater for landscape irrigation, although some larger scale projects use rainwater to flush toilets or as cooling tower make-up water. This practice can reduce potable water use while also helping to limit erosion and polluted runoff that harms 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.

Remember that harvested rainwater, whether from a rain barrel or a cistern, can never be considered potable and safe for human consumption unless the water has been properly treated and disinfected.

Clothes Washer Rebates

Replacing older clothes washers with new high-efficiency models is an easy way to trim your water bill and help conserve our precious water resources. We'll even pay you to make the switch!

“Landscape Your Lawn” Turf Replacement Incentives (Available annually, March 1 – August 15)

Marin Water is offering residential and commercial customers two options for removing an existing lawn and replacing it with a low water use planted landscape. Customers may participate in only one option. Option 2 requires a minimum of 500 square feet of turf be converted, but there is no maximum limit. Program is available annually, March 1 – August 15.

Option 1: Rebate of $1/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: Free sheet mulching 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.

Both options require customers to schedule a free water use efficiency survey at their home/business through our Conservation Assistance Program (CAP) before starting work on the project. An application and information packet will be provided during the CAP survey. (Surveys generally take 1–1½ hours.)
