What is grey water?

Explanation:
Grey water is the portion of wastewater that comes from everyday domestic activities—like sinks, showers, baths, and laundry—that goes down the drain but does not include toilet waste. In plumbing terms, this is the drain waste portion of the system, rather than black water, which contains toilet waste. It’s not fresh water, which is clean supply water, and it’s not industrial wastewater, which comes from industrial processes. So the best match is drain waste.
