Emory University student Maria Town was admittedly a little skeptical of the dual flush toilets and the mantra that accompanied them —"flush up for liquid, down for solids" at the school's newly constructed eco-friendly dormitory. But after a year of living in Turman Hall, Emory's award-winning dorm built with sustainability in mind, Town had changed her tune. "Everyone who comes into the building wants to see those toilets," said Town, who served as a resident adviser. "You realize how much water flushing really uses."
