Notes
Low concentration of pollutants

The problem with the greywater (am.eng:gray), is the large volume, over 65 cubic meters per person and year.

An advantage, , is that it is not very polluted, about 1% of the black water. Because of that, it is quite easy to purify with biological methods.
Given that it is not polluted with urine and faeces.
To avoid doing something that silly, use source separating toilets.

All grey waters are not similar. The more water saving you are, the more polluted is the greywater.

Therfore, if you use a greywater recycling system, it is good to be wasterful with water!

Do the dishes in flowing water!
