In dry climates like this one, water conservation isn't just a good idea, it’s essential, as usable drinking water becomes more scarce in the coming decade. Earlier this year, the city of Tucson, Arizona, passed an ordinance that will require new home construction to include waste systems that allows recycling of what’s called “gray water.” That’s the water that flows down the sink, shower, and washing machine drains. Although it’s not safe to drink, it can be perfectly reusable for irrigating lawns and gardens, as well as for other household uses. The homes will get rid of soap and other pollutants by using filter systems like this Brac System, which recycles gray water and sends it back to your toilet tank. Smaller amounts of gray water can also be safely collected around the house. The EPA estimates that an American household of four can use up to 400 gallons of fresh water each day. That’s 400 of these. So check your city and state’s regulations about gray water to find out how you can make your water work for you time and time again. I’m Jill Cordes.
