Scroll on the map to see how many greywater irrigation systems have been installed in your neighborhood!

Our community has an amazing opportunity to save water, energy and money by reusing laundry greywater to irrigate our gardens. Each year the average family of four uses 3,000-8,000 gallons of water in their washing machine. For 1000 families that adds up to more than 5,000,000 gallons of water a year!

Join the Monterey Bay Greywater Challenge to save water and reduce your summer water bills during this drought year and every year from now on.
Help us reach our goal of installing 1000 greywater systems!

Conserving water starts with you. Local water utilities and Central Coast Greywater Alliance members are here to help you get started with installation support and incentives.
