AKRON, Ohio – Akron Mayor Dan Horrigan announced Thursday that the city has completed a major sewer project under a federally mandated agreement to reduce pollution flowing into the Cuyahoga River.

The final sewer connection was made to the Ohio Canal Interceptor Tunnel this week, meaning all downtown sewers flow to and through the tunnel. Crews also completed nine combined sewer overflow structures for treatment at the Water Reclamation Facility.The projects are part of the Akron Waterways Renewed program, which is set to store and provide treatment of about 1.1 billion gallons of combined sewer overflow from local waterways, including the Cuyahoga River, during a year with typical rainfall.

Akron entered into an agreement with the U.S. and Ohio Environmental Protection agencies in 2014 to improve the city’s sewer infrastructure and Water Reclamation Facility and reduce combined sewer overflows and bypasses. The Ohio Canal Interceptor Tunnel has been under construction since 2016. A massive tunnel boring machine, called “Rosie,” completed its work in August 2018.
