Gray Water

Nondrinkable water used for irrigation, flushing toilets and other purposes as a way to help conserve water and energy in the home. Gray-water sources include water from tubs, showers, non-kitchen sinks and washing machines. Consider installing a gray water recycling system, which filters the nondrinkable water and stores it in a short-term storage tank for use around the house.
