Utility upgrades Melbourne CBD sewer network

City West Water has started works for the largest upgrade to Melbourne CBD’s sewer network in more than a century.

Lane reductions have begun on Lonsdale Street as the first step required for a tunnel boring machine (TBM) to construct a 900 m long and 1,400 mm diameter tunnel.

The TBM will work at a depth of 23 m below street level and will be launched and retrieved across three work sites along the west end of Lonsdale Street.

Next year, sites at Elizabeth Street and Spencer Street intersections will follow and will remain in place until late-2020.

City West Water General Manager Infrastructure and Delivery Maree Lang said while Lonsdale Street will remain open in both directions, road users should expect some disruptions over the next 12 months.

“To do this work safely, we need to reduce both eastbound and westbound lanes, as well as on-street parking around the sites,” said Ms Lang.

“We’re doing all we can to minimise the impact of this necessary work, so all of our customers can move through the area safely and get on with their day.”

Businesses and residential apartments along Lonsdale Street will remain accessible and local water and sewerage services will not be affected.

On completion, the new installation will connect to the recently completed Spencer Street sewer upgrade.

The two projects form part of an AU$80 million capital improvement program to maintain service reliability for Melbourne’s growing population.

The project is being delivered for City West Water by Rob Carr.
