Answer:

The main tunnel will be approximately five (5) miles long and will be located approximately 160 to 180 feet down in the bedrock under Fort Wayne. As part of the Tunnel Works, a mile of consolidated sewers will be constructed. Consolidation sewers are near surface sewers that will collect combined sewage from the existing sewer system and connect to drop shafts that will drop the combined sewage 160 to 180 feet deep into the tunnel. There will also be approximately two (2) miles of sewer that will connect to the south end of the tunnel that will be shallower and smaller in diameter.
