Project Status - November 1, 2017

Construction has begun on Fort Wayne's deep-rock sewage collection and transportation tunnel.

Ground was broken in June 2017.  As of November 2017, work has started on the shaft at the Water Pollution Control Plant (sewage treatment plant) where the tunnel boring machine will eventually begin its journey.  During the first week in November, the site in Foster Park where the retrieval shaft will be located has been fenced and the site is being cleared for construction.

The Tunnel Works Program represents a major part of Fort Wayne's efforts to implement the 2008 Long-Term Control Plan and associated Consent Decree with the US Environmental Protection Agency. The premier project - the deep rock tunnel - will be constructed in the bedrock deep below the city. The tunnel will collect and transport sewage from the combined sewer system to the sewage treatment plant. This sewage would otherwise discharge (overflow) into the rivers when it rains.

Where Will It Be Located?

The tunnel system will begin south of Foster Park on the east side of the St. Marys River. It will run parallel to the St. Marys River, cross Swinney Park, go through downtown then run parallel to the Maumee River until it reaches the existing sewage treatment plant, which is located on the Maumee River east of North Anthony Boulevard.  Check out the pdfTunnel Works route map.



Why is the Tunnel Works Program needed?

This deep underground sewage transportation tunnel is part of Fort Wayne's agreement with the federal government for how the City will reduce the amount of sanitary sewage mixed with stormwater that is currently being discharged to our rivers during wet weather. The plan for controlling these combined sewer overflows is intended to improve the quality of our rivers. The tunnel is part of a three part strategy to reduce the amount of combined sewage in the combined sewer system by doing sewer separation projects, collect more and transport more combined sewage to the sewage treatment plant and treat more combined sewage.

How Residents Can Help

There is a lot that residents can do to help reduce runoff amounts and prevent pollution to the rivers. When it rains, rainwater runs across rooftops, lawns, driveways, and streets, picking up whatever it comes into contact with (fertilizers, pet waste, oils, insecticides, etc.). Small household change across hundreds of homes can create big positive impacts for water quality. Learn more and take an action pledge at Residents and business properties can also help reduce the amount of runoff water entering sewer systems and rivers by installing rain gardens - Learn more at

There will be neighborhood meetings and public events as the design work on the Tunnel Works project continues. Soon you will be able to stay current by signing up for a Tunnel Works newsletter or following the social media feeds.
