Austrian Swimmers Told To Shut Their Mouths At Public Pools

Vienna officials say public pools lose 5,000 liters of water a day from swimmers swallowing water, and they can't afford to replace it. From the article: "Replacing that much water also has an environmental as well as financial cost, authorities say, due to the need to chemically treat the water." I can't wait to see what happens when someone tells them about evaporation.
