WICHITA FALLS — The idea of turning treated sewage into drinking water may give some people pause.


" But with lake levels having officially dropped below 40 percent of capacity on Tuesday, this onetime oil boomtown plans to move ahead with the technology. The city hopes to produce five million gallons of water a day next year with potable-reuse technology, which officials say is safe."


"In direct potable-reuse, treated wastewater goes through additional chemical and biological processes and extensive filtration and then usually mixes with the regular drinking water supply before going through normal drinking water treatment.

The Big Spring plant will be the first of its kind in the nation. El Paso and Orange County, Calif., also have pioneering reuse projects, but their treated wastewater gets sent through an aquifer before being pumped up for further cleaning. At Big Spring, there is no aquifer step."

They should lay a new pipeline and only send the treated sewer water back to be used only in toilets and not for drinking.
Toilets uses half of all indoor household water so it would be awesome.
They should also stop treating grey-water and just have customer send it outside for landscaping.
If they did that then they would get to use both grey-water and black water twice.
While also cutting the cost to treat sewer water. And no one has to worry about drinking sewer water.
Roof water catchment should also be used to flush the toilet and for landscaping even if the roof material is less than ideal or toxic.
