Ft. Wayne has approved consulting contracts

Ft. Wayne has approved consulting contracts for the $150 million CSO tunnel project, which includes 5 miles of 12-ft ID tunnel.

The first contracts in the $150 million Ft. Wayne CSO tunnel project were approved on June 25 by the Ft. Wayne Board of Works. The project, known as Ft. Wayne Three Rivers Protection and Overflow Reduction Tunnel (3R-PORT), is part of an EPA-mandated program to reduce combined sewer overflows into area waterways.

Contracts expected to be awarded include Black & Veatch, $12.34 million; Arcadis ($1.78 million); and CH2M Hill, $1.04 million.

The tunnel project includes 5 miles of 12-ft ID tunnel, 2 miles of 24- to 108-in. consolidation sewers, and 13 drop shafts. The tunnel will be constructed at an average depth of 150 ft with construction shafts expected to be up to 40 ft in diameter.

Additionally, the program includes the Foster Park Relief Sewer, an upstream extension of the tunnel that involves the construction of 2 miles of 48- to 84-in. sewer, and a 20 mgd dewatering pump station.

Construction of the tunnel and pump station is expected to begin in mid 2017 and be complete by 2023. Construction of the Foster Park Relief Sewer is anticipated for 2022 to 2025.
