An excellent resource on the topic. –School Library Journal, starred review

In the developed world, if you want a drink of water you just turn on a tap or open a bottle. But for millions of families worldwide, finding clean water is a daily challenge, and kids are often the ones responsible for carrying water to their homes. Every Last Drop looks at why the world’s water resources are at risk and how communities around the world are finding innovative ways to quench their thirst and water their crops. Maybe you’re not ready to drink fog, as they do in Chile, or use water made from treated sewage, but you can get a low-flush toilet, plant a tree, protect a wetland or just take shorter showers. Every last drop counts!
