The contract to construct the Pawtucket Tunnel will include the launch and recovery shafts (which will become permanent access shafts), two to three drop shafts with connecting adits at existing out- fall locations, and an underground shaft- or cavern-style tunnel pump station. chanical fit out of the tunnel pump sta- tion will be performed under a separate con- tract. Construction of diversion structures, gate and screening structures and consolidation conduits at existing outfall locations will be performed under separate contracts as well. The launch shaft and tunnel pump sta- tion will be located a C's Bucklin Point Wastewater Treatment Facility in East Providence, Rhode Island. The alignment will be parallel to the Seekonk River and Blackstone River, and end near the border of Pawtucket and Central Falls, Rhode Is- land.
