This is potentially important because we consume a lot of water. The USGS estimates that we in the US use about 400 billion gallons per day. Given that a ton is about 240 gallons, that's over 1.7 billion tons of water. At an added cost of 65 cents per ton that means we save about $1 billion every day we are able to avoid desalination to meet our water needs. But with over 96% of the earth's water accounted for by sea water, it is comforting to know that for a bit less than half the cost of Social Security we could find alternative water sources. Here's hoping it doesn't come to that!
