If you have followed the news at all this summer, you have probably seen articles about the severe drought. The Southwestern states, which depend on the Colorado river and its Reservoirs, are suffering the most. This unprecedented lack of surface water has emptied reservoirs and forced mandatory water restrictions in Los Angles, Phoenix, Albuquerque and many more. One practical solution many cities are considering is wastewater reuse. In the US, treated wastewater is almost always higher quality than the river or lake it is sent back into. So, instead of sending the water downstream to the next user, cities will need to recycle and reuse this water locally. Landscape irrigation and agriculture are the most common opportunities. Going forward membrane technology will need to play a larger role in this transition.
