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 – January 26, 2021
Along its current drive, Salus built 1,347 rings and tunneled about 6,765 feet.
BBJV continuously monitors tunneling progress and makes adjustments as needed to ensure safe and smooth tunneling operations. Since the tunneling has been ongoing since June 2020, BBJV is looking to plan a stoppage to inspect Salus’ cutter head for wear and tear. This will help determine its condition, and whether there is need to replace any of these tools.
The first phase of installation of Fiberglass Reinforced Plastic (FRP) carrier pipes is almost complete.
