(often called graywater)
Greywater is any household wastewater with the exception of waste water from toilets which is known as black water.
50-80% of household waste water is greywater from Kitchen sinks, dishwasher, bathroom sinks, bathroom tubs and showers.
IF you use composting toilets, 100% of your household waste water is greywater.
Before implementing any greywater systems CONSERVE WATER FIRST!
Be sure you have taken all possible measures to conserve water first eg: low flow showerheads, low flush/composting toilets, aerators on faucets, efficient front loading washing machines, natural landscaping, rainwater harvesting.
Small scale grey-water recovery systems available: AQUS system which sanitizes water form the bathroom sink before plumbing it into the toilet tank to supplement city supplied water.
