Ten years after it was opened, the Adam Joseph Lewis Center for Environmental Studies at Oberlin College continues to grow and evolve. Large windows allow in ample natural daylight, while a constructed wetland and 7,500-gallon rainwater cistern manage all stormwater on-site.
The Adam Joseph Lewis Center for Environmental Studies' Living Machine is a wastewater pruification system that treats the building's blackwater. Wastewater is fed into the machine, where microorganizsms and plants break down impurities. The water is then pumped to a tank for reuse in toilet flushing and landscape irrigation.
