Wellesley Trails Committee member and Wellesley resident Peter Rovick explains in a guest column in the Globe how he built a rain water barrel with a used garbage can and less than $22 worth of other materials. The idea: using rain water to water gardens and shrubs.
(Of course, you could collect even more otherwise wasted water by setting up barrels to catch the water shooting out of those automated sprinklers in town that mainly misfire onto sidewalks and streets.)
