When the sewage treatment system failed at Vermont's busiest interstate highway rest area, the Guilford Welcome Center, state officials decided to install an innovative system called the Living Machine. The system uses a series of tanks containing plants and other organisms to naturally clean wastewater. The Living Machine is a biological system consisting of a series of reactors housed in high-density polyethylene tanks. Each reactor has a different ecological environment designed for a specific treatment purpose. This ecological diversity includes plants, aquatic insects, snails, aquatic worms, and other flora and fauna. Sewage from the rest area is treated to Vermont's reuse standards and recycled to the rest area as flush water in the toilets. The Living Machine was designed to treat wastewater from up to 4,300 visitors per day. |
