California-based Water Wise Group makes the Aqua2use Greywater System, which was selected recently as a Top-10 Green Product for 2012 by Environmental Building News and GreenSpec. The product is meant to be a cost-effective way to save water and could help a family of four conserve up to 40,000 gallons of water annually through the reuse of washing machine, shower, and bath water.
Aqua2use may be connected with a drip irrigation solution to distribute water that’s been filtered by the grey water system. The whole setup can be installed in an afternoon by a licensed plumber without extensive plumbing changes, according to Water Wise Group. Aqua2use sells for about $399 (gravity operation) or $649 (pump).
