If the recent downpours have you thinking about rainwater collection, you're probably not alone. One good rainwater-storage option is the Rainwater HOG (which, fittingly, means “H20 gray” or “gray water”). Designed in Australia and sold all over the world (including many stores in California), the HOG barrel stores rainwater, fits into tight spaces and easily links to other systems—including showers, toilets and additional HOG barrels. Some HOGs have found their way into schools in the Bay Area, but their slim profile makes them a good fit for residential and commercial applications as well.
