What is the Gravity Pipeline Project?
The Gravity Pipeline (GP) Project consists of the design, construction, permitting, start-up, commissioning, and closeout of approximately 17,600 feet of wastewater gravity FRP pipe inside a concrete-segment tunnel. The work includs three shafts and will interface directly with the Front of Plant (FoP) Project at the Receiving Lift Station (RLS). Work is being implemented under a Progressive Design-Build procurement process.

TBM Status Update – May 17, 2021
As of Monday, May 17, 2021, Salus tunneled 11,098 feet from the launch shaft and built 2,214 rings. Salus remains on target for break-in to the surge-flow splitter (SFS) shaft.
The jet grout columns and permeability test production columns were recently completed. Quality control work on the jet grout columns adjacent to the SFS shaft continue, assuring that the columns meet the required strength and permeability tests. These activities will ensure a safe break-in when the TBM enters the shaft.
BBJV and Shea Parsons Joint Venture continue coordination efforts to prepare for the safe arrival of the TBM.
