"Would you drink sewer water repurified and turned into drinking water? What if it was in a fancy bottle, and cost $3 a liter?  While the idea of &amp;#8216;toilet to the tap&amp;#8217; can be made into something gross, repurification could become more and more important as the world population grows. There&amp;#8217;s a lot of water on the planet, but &amp;#8216;fresh&amp;#8217; water sources aren&amp;#8217;t infinite. &amp;#8216;Toilet to the tap&amp;#8217; may be the wave of the future."^^<http://www.w3.org/2001/XMLSchema#string>
