This LEED Platinum home plot exhibits a large variety of sustainable features, including this system for rainwater collection, which provides for 90% of the home’s water use. Several aluminum gutters attached to the house serve to capture and siphon rainwater down to a storage tank further down the plot. Since it is gravity fed, no pumps are required to move the water to the tank, though  the home still has a water supply pump to bring water to the fixtures.

The house also incorporates a PEX (cross-linked polyethylene) manifold plumbing system, which serves as a main control center for all of the home’s water distribution lines, and allows for great ease of use. With this, individual lines to specific fixtures may easily be shut off when needed, and entirely from a central location.
