Utility names sewer upgrade TBM

A utility in California, US has named a tunnel boring machine (TBM) which will be used in a sewer upgrade project.

Salus, named after the Roman goddess of safety and wellbeing, will be used by Silicon Valley Clean Water (SVCW) as part of the utility’s US$495 million Regional Environmental Sewer Conveyance Upgrade (RESCU) program.

RESCU includes the rehabilitation of more than 5 km of raw wastewater conveyance system in Redwood City and the installation of a new pipeline.

The US$18.2 million Herrenknecht TBM will arrive disassembled from Germany in July and be reassembled underground to a diameter of 4.87 m and length of 198 m, prior to commencing two years of work.

Salus will first construct a 1.6 km segment of tunnel to connect the new pipeline with a new force main installed on Inner Bair Island.

The TBM will then install a second section of tunnel starting from a launching shaft located north of the San Carlos airport and extending SVCW’s treatment plant.

SVCW provides wastewater services to more than 220,000 residents and businesses in Belmont, San Carlos, Redwood City and the West Bay Sanitary District.
