The Rainwater H2OG is a modular rainwater storage tank designed for use in tight spaces such as under decks, against houses, or even within walls. Two versions are available: a potable water tank made from virgin food-grade polyethylene, and a non-food-grade tank made with 15 percent recycled content. Each module holds 50 gallons of water that can be used for gardening, irrigation, toilets, laundry, or (with the food-grade tank and after proper filtration) potable water. When installed within a building envelope, the tanks can serve as thermal storage for passive solar heating systems. These 71” x 19.5” x 8.5” tanks can be installed horizontally or vertically, and they can be installed in series. They come with inlet screens, elbow vents, and outlet valves: tanks and components are designed for future reuse. Rainwater H2OG is available as a stand-alone tank that is plumbed into the downspout or, alternately, as part of a complete rainwater harvesting system called Rainwater Rescue, which combines the Rainwater H2OG tank with GLI Systems’ RainTube roof-level water collector. Standard colors include bronze or olive green, but other colors are available for orders of 20 or more units. Rainwater H2OG comes with a one-year guarantee. A 350-gallon H2OGzilla tank is planned for release in 2009.
