For those who are interested in reducing potable water use at home, graywater reuse can be an excellent option. A graywater system can be something simple like keeping a bucket in the shower to collect water as you wait for it to warm, or elaborate like an irrigation system with electronic controllers and pumps. The level of complexity and amount of water reused is up to the user.
One of the simplest and most common graywater systems in residential settings is Laundry-to-Landscape. An L2L system diverts water used in your washing machine into your landscape. When completed as a “Do-It-Yourself” project, the cost to install this system is about $200-300. The average family can save up to 10,000 gallons of potable water each year by installing an L2L graywater system.
While permits are not required for an L2L system in California as long as it complies with the California Plumbing Code, each municipality may have additional requirements. After viewing the video below for more information on installing a L2L system, please see the list of additional resources to connect with your local government for requirements in your area.
