Laura Allen, cofounder of Greywater Action, a group that encourages conserving and reusing household water, is teaching Californians how to reclaim and recycle “gray water.” Typically, gray water includes the discharge from washing machines, sinks, showers, and baths, which is then used to provide moisture for outdoor plants.

Many institutions, corporations, and municipalities around the world use gray water but activists say there’s still a long way to go. ‘This is the way the world is going. We all need to learn to save water,” says Trent Cawthon, a handyman from Redondo Beach, Calif., who feels that expertise with grey water systems will make his services more valuable.

John Leys of Sherwood Design Engineers in San Francisco said ‘Ten years ago, we were not seeing any demand for grey water systems,” but now clients of all types are requesting projects that range from simple and inexpensive backyard irrigation retrofits to complex, multipurpose grey water systems that are part of the design from the beginning. Leys notes that many businesses have begun to see that reclamation and reuse make sense from both a business and an environmental standpoint.

For instance, if a development of 10,000 new homes reduces its overall potable water use by as much as 25 percent, that means a huge savings in construction and utility costs. Leys believes that it’s important to plan for solutions in advance of a water crisis, and that when and how that’s done will become critical.
