What is the difference between Greywater and Blackwater?

Grey water is all the wastewater that drains from your shower, kitchen, bath, and bathroom basins.

Grey water has some bacteria, but it can be treated and reused in gardens and lawns,

if done properly. Black watercontains human waste, feces, urine,

toilet paperand is unsafe. It must be stored in its own tank and

disposed of very carefully.
