Gray water
Also called: sink water, wastewater from sinks
Gray water is the used water from handwash stations and restroom trailer sinks, collected in a separate tank and pumped out by the service truck. It is not the same as the black water from toilets, but it still cannot be dumped on the ground at most sites.
Handwash stations have a gray water tank roughly the size of the fresh tank, so a station that runs out of fresh water is also nearly full of gray water. Some venues allow gray water to drain to a sanitary sewer; check before you let it run.
