About NSIT:

The City of Akron is constructing the Northside Interceptor Tunnel (NSIT) project to control and reduce combined sewer overflows. One component of the project is a large diameter tunnel diversion /flow control structure that will facilitate tunnel storage, divert dry weather flow to the treatment plant, and divert large wet weather events that are greater than the tunnel capacity to the river. The structure is designed to pass up to 1.2 billion gallons per day of flow. Tour will explore project background, walk through of the portal and starter tunnel excavations, discussion of TBM assembly and launch plan as well of tour of recently launched Herrenknecht hard rock TBM Elaine while mining.
