Water water everywhere, and not a drop to drink?

In parts of the southwest of the US, there are towns where running water can be expected for only three hours per day. This isn't because they are backward, but because there is a drought.

In other parts of the southwest of the US, and the rest of the world, thousands of gallons of water are put into landfills as a result of discarded liquids from airport security lines.

It has been many years since the "no liquids" rule, and little has been done to address the practicality of it. In principle it works, however, people bring huge amounts of liquids with them to the airport and then discard perfectly good, unused liquids in the trash in order to pass security.

Why can't those liquids be recovered and put to good use? Surely, those liquids can be used for irrigation, or perhaps it could be filtered and cleaned and then re bottled and sold. Dasani and Aquafina do this - and their product isn't stellar.

Any way you look at it, water is too precious a resource to waste for any reason and the longer it takes to realize this, the more abject the shortages will be.

The US is in trouble with their water resources. The water disposed off at airports in the form of mineral water, juices, sports drinks and other types of sodas won't be enough to reverse the drought. It would, however, be enough to help some poor families to have drinking water for one more day.
