A rapidly growing population, persistent drought and outdated water supply infrastructure are among big challenges facing Arizona in ensuring clean, affordable and reliable water supplies. ASU’s Water Institute recently hosted the national Rethinking Water West conference to explore potential solutions to a variety of water-related issues throughout the U.S. Southwest. The Water Institute’s director stressed the need to fund and develop systems to deliver water security efficiently and affordably using cutting-edge water monitoring, prediction and management tools. Rujie Zeng, an assistant professor in ASU’s School of Sustainable Engineering and the Built Environment, discussed about how artificial intelligence and machine learning technologies could help produce robust and adaptable tools and systems to aid the cause.
