How To Use Graywater

Reusing household graywater to irrigate plants, flush toilets, and wash clothes is a smart way to avoid rising water costs and preserve valuable resources.

The indoor graywater-irrigated planter bed in Wellfleet Audobon Sanctuary, Wellfleet, Massachusetts, manages all of the graywater from the building’s sinks. Treated water also flows to the exterior gardens to irrigate and fertilize the plants.
