Reused Grey Water Cuts Water Usage, Saves You Some Green

Some municipalities, homebuilders and water-recycling manufacturers are increasingly making that a viable option. In the United States, where the average household uses more than 300 gallons of water a day, one of the greatest untapped resources is grey water.
