What is Grey Water?

"Grey water" is a term that represents a variety of moderately clean water flows you might find in a building. Typically, it includes water that been used in a sink, shower, bathtub, washing machine, dish washer, or other device that leaves the water unclean, but significantly cleaner than the "black water" that comes out of toilets and garbage disposals. Grey water is not potable (drinkable), but it is also not useless. Because it contains only small amounts of soap, dirt, and other relatively mild components, unlike black water, grey water can be cleaned up onsite, and reused for non-potable purposes such as irrigation, cleaning, etc.
