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 graywater 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.

Benefits of Reusing Graywater:
  • Save water – depending on how much potable water you use for irrigation, you could save thousands of gallons of water a year
  • Save money  you’ve paid for the water, why not use it a second time??
  • Enhance Safety – you’ll need to use gentler, non-toxic laundry soaps which is safer for both you and the environment
  • Create Beauty – you’ll increase the beauty and bounty of your garden by irrigating with graywater
  • Build Community – build community by working together with neighbors and friends to install your graywater system
  • Build a Movement – get educated, engaged, and trained and help build a graywater movement!

Laundry-to-Landscape System Overview

California plumbing code defines graywater 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 

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 graywater from simple Laundry-to-Landscape systems. Storing graywater requires a permit and filtration, which adds cost and complexity to the system.

Ecological Landscaper Referral List – February 2017 

No. In the State of California, water from dishwashers and kitchen sinks is not considered to be graywater due to potential pathogens. That said, there has never been a documented case of illness in the United States linked to graywater.
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 the graywater does not come in contact with the edible part of the plant. Avoid acid-loving plants like blueberries, rhododendrons and ferns.
