Endorsing MM 's notings, wish to further add that wwt effluent is not consistent, may become deficient if there is a lapse or mal function Etc.
Hence the two are left separately. If you are very sure and all parameters are compliant, then after phyto remediaton and extended aeration theceffluent more than compliant, may be taken for rechrge aquifers Etc..
Well wishes.
