Build It Green! 2008: A Rainwater-Harvesting and Filtration System
Requirements: 1 metal roof, 2500 gallons of rain, and the desire to save the planet
If you thought you were conserving water by installing a 2.5-gal.-per-minute showerhead or buying a low-flow toilet, consider what Craig Kelley does to conserve water: He makes his own-or rather, he converts his own with a rainwater-harvesting and filtration system. Craig’s system converts rainwater to drinking water by capturing rainfall with standard gutters and pre-filtering it with a “roof washer”; then a three-stage filtration process ensures the water meets drinking-water quality standards.
