gray waters

Dull, overcast ocean

Gray water (also greywater or grey water) is wastewater from household sources other than toilets—sinks, showers, washing machines, dishwashers.

It contains soap and minor contaminants but no sewage, making it suitable for reuse in irrigation or toilet flushing: We installed a system to collect gray water for the garden.

Distinguished from black water, which contains human waste.
