About 40 ASU chemical engineering students got a tour of one of Tempe’s water plant recently to learn how the city is aiding municipalities and communities as they try to implement sustainable operational and environmental solutions for their parks, water treatment and management systems and related facilities. It’s part of a project called Project Cities, designed to engage the university and communities in collaborating to address local quality of life needs. It’s challenging Fulton Schools students to use what they are learning in chemical engineering studies to devise scientifically grounded solutions to solve some challenge the city has faced for years.
