The RainTube was one of many designs at West Coast Green that make simple modifications to existing home building architecture for greener gains.
The simple tube, which lays in standard roof gutters, collects rainwater at a rate of up to 100 inches an hour and stores the runoff in underground tanks.
The system not only protects the foundation of the home from excess water, the company says, but also provides recycled water for use in home maintenance and gardening.
