TPC will be utilized on the Blue Plains Tunnel, a 4 mile tunnel along the Potomac which is a portion of the District of Columbia Water and Sewer Authority's (DC Water) massive Clean River Project aimed to significantly reduce combined sewer overflows and improve water quality.

Scheduled for completion in 2022, it will become part of a 12.8 mile tunnel that will serve as an enormous holding tank during rainstorms.  TPC will be used not only to monitor the progress and performance of the TBM but also be used to analyse hourly measurements from more than 1000 monitoring devices.
