he Akron Waterways Renewed! program provides trolley tours several times a month for anyone interested in learning more about Akron’s efforts to improve our water and sewer infrastructure. The tour starts inside Akron’s historic Mustill Store with a brief video of the Ohio Canal Interceptor Tunnel (OCIT), followed by a few minutes of Q & A. Participants then board a City trolley and are able to go to many of the sites associated with the program. Participants are able to exit the bus
and see up close exactly how Akron’s sewer system works, what combined sewer overflows actually are, and what green infrastructure looks like. City of Akron representatives and engineers lead the tours and answer any questions participants may have. The City encourages anyone and everyone to join a tour. It gives residents an opportunity to tangibly see their money at work and how Akron's antiquated sewer infrastructure is being improved for the 21st century.

Engineering Program Students learned how sewage is cleaned and returned back to waterways at Akron’s Water Reclamation Facility.
he All-Akron Student Engineering Program (AASEP) is designed to provide valuable experiential learning for high school students interested in pursuing a career in various engineering fields. The program, sponsored by the City of Akron Engineering Bureau and Akron Waterways Renewed! program, provides an up-close look at careers from chemical, hydrological and biological engineering, to mechanical, electrical and civil engineering. Students are exposed to Akron’s water system from intake—what it takes to provide municipalities with clean and safe drinking water—to treatment—what it takes to treat and return water back to the environment. AASEP has three goals: Exposure, Experience, and Employment. Students are exposed to the “E” fields of the STEM curriculum, and are given valuable experience during their internships with local engineering firms. Allowing student

learners to be in the room with the firms that are designing, developing, and managing various projects under the AWR! banner, helps lay the foundation for what they can expect in their future and expands their network within the Akron engineering community. That exposure could be key in helping a student engineer land a job in Akron once they finish their degree. 2016-2017 is year two of AASEP; 41 students from eight local high schools are represented within the 18 participating professional services firms in the Akron area— including the City of Akron. This year, the program consisted of 29 male students and 12 female students. Students who are currently juniors in the program are eligible to apply for their senior year. The goal is to continue to expand the program and help shape the future engineers of Akron and to shape the City itself by retaining professionals.
