What is wastewater?

Question

thanks to those ppl that answer(:

Answer 1

It is water that has been used to wash clothes,the house(mopping), showering, dish-washing etc. It is also known as grey water I believe. The effluent from the toilet is classed as waste water also I think.

Answer 2

The best way to learn is to review the references given.  There are many types of wastewater including sanitary waste from humans and the many types from industrial processes.  It really is any water that is not directly reused.
