Project Status

July 18, 2018 - This week the tunnel working shaft is about 198 feet down and the Pump Station Shaft 173 feet down this week. The final destination is around 220 feet down. Work continues at a third neighborhood drop shaft near the intersection of Coombs and Cochran Street where a 50-ton steel casing (drop shaft liner) spanning 80 feet in length and 12 feet in diameter was delivered late last week.  Click to see casing crossing Tecumseh Bridge

July 11, 2018 --  Work will begin next week at the drop shaft just south of the Maumee River at River City.  The working shaft is about 180 feet down and the Pump Station Shaft 160 feet down this week.  The photo shows the rock pile of the rock pulled from the shafts.

June 22, 2018 --  Progress continued at the two neighborhood drop shaft sites and at the working shaft sight.  Late in the week, heavy-rain slowed the project.  Click for aerial view of work near Water Pollution Control Plant.

June 15, 2018 -- The Drop Shaft at Camp Allen, near Main Street and the St. Marys River, is moving along.  This week a 50-ton casing was installed. Click here for video of Camp Allen Casing

June 8, 2018 --The working shaft and the pump station shaft are progressing on Dwenger Avenue.  The working shaft is at about 130 feet and pump station shaft is about 120.  Click on this link showing aerial video of the progress.

The Drop Shaft on Brown Street is under construction. Click to see the 50-ton, 70-foot casing at Brown Street.  It will collect combined sewage and drop it to the tunnel -- keeping it out of the St. Marys River. 

Work at Foster Park will begin again in September.  Equipment being used at the Pump Shaft will be moved to Foster for that work.

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.

pdfQuestions and Answers about Tunnel Works Program

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.
