The city of El Paso, Texas, may soon become the first large city in the US to use treated sewage water for its drinking water needs. 

The amount of snowmelt feeding the Rio Grande has dropped 25% since 1958 and is “critically low,” J. Phillip King, an adviser to the Elephant Butte Irrigation District, told CNN.

The use of treated wastewater will add a significant source of water to the city’s supplies.
