Gravity Pipeline June 2021

Good news! Salus, the mighty tunnel boring machine, has broken through the shaft! Having tunneled nearly 13,000 feet from its launch shaft, which is at the intersection of Shoreway Road and Holly Street, Salus has safely completed its second tunneling drive. Even more good news, Salus arrived on time and on target at Silicon Valley Clean Water (SVCW)’s Wastewater Treatment Plant. This is a major milestone and accomplishment for SVCW and RESCU’s Gravity Pipeline project team.

 Now what? Salus tunneled and broke through into a mix of backfilled soil and water within the receiving shaft. Barnard-Bessac Joint Venture (BBJV) (SVCW’s contractor partner) will be dewatering the shaft and removing Salus, together with its gantries and electrical equipment, from the tunnel and shaft.

Pipe installation within the completed tunnel will take place once Salus is removed from the shaft. This installation will be carried out by a pipe installer and will span the distance from the receiving shaft to the launch shaft.

A big CONGRATULATIONS to SVCW and RESCU’s Gravity Pipeline project team!
