Reusing Waste Water?

Is it okay for irrigation, watering lawns, manufacturing, drinking water, …oops, too far?

The New York Times reports that more and more communities are looking to reuse their wastewater.

A new report from the National Academy of Sciences said that if coastal communities used advanced treatment procedures on the effluent that is now sent out to sea, it could increase the amount of municipal water available by as much as 27 percent.  Right now most of these communities are in the arid west or south, but when will we see this in the Great Lakes?
