Texas State University’s Keisuke Ikehata, Ph.D., an assistant professor in the Ingram School of Engineering, joins the Big Ideas TXST podcast to discuss an innovative pilot program to convert wastewater into purified drinking water.

Texas’ rapid population growth combined with ongoing drought conditions has led to water shortages across the state. In the face of this challenge, Ikehata sees an opportunity for the public to embrace the idea of using treated wastewater for daily needs, a process referred to as potable water reuse. Ikehata and his students have partnered with the San Marcos Wastewater Treatment Plant on an advanced water purification system that turns more than 5 million gallons of wastewater into clean, environmentally safe water on a daily basis.

An expert in advanced water and wastewater treatment and sustainable water resources management, including water reuse, desalination and stormwater management, Ikehata earned his doctorate in civil and environmental engineering from the University of Alberta, Edmonton, Canada. In July 2019, he joined TXST as one of four founding members of the civil engineering program. Prior to joining TXST, Ikehata worked for more than eight years as a technical specialist/R&D manager at a water resources engineering firm in Orange County, Calif. and eight years in academia in California, Alberta and Kansas.
