(pronounced GRAY-wah-ter)

If you’ve studied for a LEED AP exam or worked on a project going after LEED certification, then you know a little something about graywater. The Uniform Plumbing Code defines it as “untreated household waste water which has not come into contact with toilet waste. Gray water includes used water from bathtubs, showers, bathroom wash basins, and water from clothes-washer and laundry tubs. It shall not include waste water from kitchen sinks or dishwashers.” Of what use is it” Graywater is a good way to reduce fresh water usage as it can be used for flushing toilets and watering lawns.
