what is graywater
1 answer
Graywater is wastewater generated from activities such as laundry, dishwashing, and bathing that does not contain human waste. It is relatively clean and can be reused for purposes such as irrigation, flushing toilets, or even some non-potable household uses. Graywater should not be confused with blackwater, which is wastewater that contains fecal matter and is considered to be more contaminated.
