Graywater, the recycled water collected from your sink, shower or washing machine, is becoming increasingly popular with California’s building industry. By selling new homes with built-in systems for reusing water, developers may propel the practice into the mainstream.
An Australian company, Nexus eWater, is positioned to be a key part of the transition. The company’s home graywater recycling system is the only one that has passed a key certification permitting the water it cleans to be used in toilets and on lawns under California’s building code.
The system sends dirty water gathered in a tank under a house through bubbles, filters and a zap of ultraviolet light.
Megabuilder KB Home has placed Nexus systems at 52 brand new homes at Sea Cliff, a San Diego County development. The company won’t disclose how many have sold, though sales representatives say interest is strong.
