MTBM completes major works under Melbourne

The 9 m long, 1.5 m diameter MTBM has been installing more than 700 m of new sewer main under Melbourne’s CBD between Lonsdale Street to Flinders Lane as part of City West Water’s Spencer Street Sewer Upgrade.

The new sewer will connect with an existing pipeline to support the population growth in city over the next 35 years.

Quinn Civil is the Principal Contractor of the project, with microtunnelling operations subcontracted to Bothar Boring.


On Friday 21 December 2018, City West Water announced that the Spencer Street Sewer Upgrade was complete, finished ahead of schedule, safely and within budget.

The upgraded sewer has been connected to service residents and commuters who live and work along Spencer Street, increasing the existing capacity of the 122-year-old sewer by approximately 25 times.
