Ummm it's called tertiary wastewater treatment. look it up. when i was studying ecology (for NRM) in the 70's the nearby town had a tertiary treatment plant that our class was able to spend weeks studying on site. some of the water eventually made back into the public drinking water. Even a drinking fountain in the lobby from the treated water.Butcher Bob wrote:Maybe on the space station, but here on planet earth, rural areas use septic fields to return untreated wastewater right back into the aquifer, and in urban areas the wastewater is treated and dumped back into rivers, lakes, oceans, etc.Prawn Connery wrote:Probably in your drinking water.Butcher Bob wrote:And where exactly do you think that treated waste water goes?
Back in the 1975 !! nutin' new, more so as natural aquifers are being depleted i'm sure.
