Project Title: Design of a Wastewater-to-Drinking Water Facility
Project Type: Faculty

Description: Significant research and funding has gone into developing so-called “toilet-to-tap” systems that can treat wastewater to make it 100 percent safe and potable in a single closed loop The goal of this project is to design a treatment facility and process to treat 30 million gallons per day of wastewater and turn it into drinking water. Wastewater of the same composition as that found in Tucson, Arizona, was evaluated and a full-scale process and operation were designed to remove solids and harmful chemicals in the water, and further purify it to EPA drinking water standards. The team incorporated features such as gravity-induced flow and recycling bacteria into a bioreactor, and the entire process was designed with economic feasibility, and thus the consumer’s water bill, in mind.
