本题解释:
A item is just recycled water.

Graywater is defined by the Uniform Plumbing Code (UPS) as untreated
house-hold wastewater which has not come into contact with toilet waste or
kitchen sinks.
Graywater includes used water from bathtubs, showers, bathroom wash
basins, and water from clothes-washer and laundry tubs. It does not include
water from kitchen sinks or dishwashers.
