QLD sewer network set for upgrade

The sewerage network upgrade will occur in Mollison Street, West End, and will involve the construction of a new 430 m, 500 mm diameter sewer from Boundary Street to Hockings Street using trenchless methods.

A tunnel boring machine will dig underneath the intersection of Boundary Street, along Mollison Street and under Montague Road in order to connect up to the existing sewerage network at Hockings Street.

Queensland Urban Utilities (QUU) Chief Operating Officer Robin Lewis said the project will improve capacity to cater for future development.

“We recognise population growth and the increase in high-density living in the area will put pressure on local infrastructure,” he said.

“The Mollison Street upgrade will ensure the West End sewerage network will continue to serve the local community and protect against sewage overflows in times of wet weather or high demand.

“Once connected, this main will link up to the Toowong Sewer via a connection under the Brisbane River.”

Works started in late April and are expected to take six months to complete, depending on ground and weather conditions.
