Greywater-harvesting food-producing outdoor shower

Plant your greywater as you shower to grow a fragrant, edible, privacy screen that also feeds & shelters chickens, goats, pollinators, and native song birds.

Two drains, each to a different gravity-fed branched drain system, distribute the greywater to multiple plantings with the free power of gravity. With this system the soil drains well and stays aerobic, greywater does not puddle, and there is no odor.

This simple, inexpensive system (no pumps or tanks) uses common plumbing parts, and no expensive or hard to find valves.

Be sure you pipe maintains a minimum 2% slope — more on how to do this in “Rainwater Harvesting for Drylands and Beyond, Volume 2, 2nd Edition

Filmed in winter of 12-2021 in Tucson, Arizona.
