In our LEED Project, the water used for Urinals and WC is recovered of the subsoil (freatics water). So, in Water Use Reduction Calculator, i have indicated the total non-potable water supply to rest of Annual design water consumption.
In preliminary review, the reviewer ask us if the recovered water is used only for WC and Urinals or if this water has other purposes.

Is possible to achive compliance with this strategy?
