Did you know the average family of four uses 5,000-8,000 gallons of water annually in their washing machine alone? If 100 families installed a simple Laundry-to-Landscape greywater system, we could save 500,000-800,000 thousand gallons of water a year and put that precious water into our gardens instead of sending it the waste water treatment plant.

Laundry-To-Landscape (L2L) System Overview
California plumbing code defines greywater as wastewater generated from bathroom sinks, showers, tubs and washing machines. Though all of these sources represent great opportunities to transform waste to resource, the Laundry-to-Landscape system is the simplest, most cost-effective, and does not require a building permit, making it an excellent place to start!
Frequently Asked Questions (about greywater)
No, the simple Laundry-to-Landscape system does not require a permit. For more complex systems like your shower and bath (often referred to as a “branched drain system”) you will require a relatively straightforward plumbing change permit from your building department (often ranging in cost from $50-$100).
No. The code does not permit storage of greywater from simple Laundry-to-Landscape systems. Storing greywater requires a permit and filtration, which adds cost and complexity to the system.

No. In the State of California, water from dishwashers and kitchen sinks is not considered to be greywater due to potential pathogens. That said, there has never been a documented case of illness in the United States linked to greywater. Nonetheless, there is the potential for pathogens and water-borne diseases so the 100 Greywater Systems Challenge is committed to providing engaging, informative workshops to make sure that greywater systems are installed safely and properly.
Just about any woody perennial works! We recommend fruit trees, berry bushes, and perennial vegetables (like artichokes). You can also irrigate annual non-root vegetables like corn and beans as long as it does not come in contact with the edible part of the plant. Avoid acid-loving plants like blueberries, rhododendrons and ferns.
