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 – April 5, 2021
Salus continues tunneling at a steady rate towards the SVCW wastewater treatment plant. As of Monday, April 19, 2021, Salus tunneled 10,267 feet from its launch shaft and built 2,048 rings.
Part of the preparations for Salus’ break in at the front of plant, BBJV is working on ground improvement around the break in shaft by installing jet grout columns. Jet grout columns are created by using high velocity fluid jets to mix cement and water with the soil in the ground. Ground improvement will allow BBJV to manage the groundwater surrounding the TBM receiving shaft when Salus breaks into the receiving shaft., making for a safe completion of the second tunneling drive.
