Graywater and Rainwater Harvesting


Arizona Regulations Allow for Home Irrigation with Graywater.

“Using your graywater is a great way to practice the motto ‘Reduce, Reuse, Recycle.’ By using graywater, you reduce the need to pump precious groundwater, and you reuse a resource so valuable in the desert.” So states a press release from the Water Conservation Alliance of Southern Arizona (Water CASA), an organization representing various water districts and the U.S. Bureau of Reclamation.

The Arizona Department of Environmental Quality has issued regulations allowing the use of reclaimed water by homeowners. The guidelines make it simple and affordable for residents to legally use graywater for landscape irrigation. There are a few simple restrictions that must be observed, but it is a giant step forward in the area of reusing graywater.Plantbasins

After in-depth research by Water CASA revealed the widespread reuse of graywater by homeowners in Southern Arizona (the most common use being the surface irrigation of shade or ornamental trees), state officials decided to make the practice allowable by law without a permit under limited conditions.
