Spencer St sewer upgrade

We have an exciting new project starting in Melbourne's CBD.

We will be constructing over 700 meters of new sewer mains along Spencer Street in Melbourne’s CBD – between Little Lonsdale Street and Flinders Lane.

Why this upgrade needs to be completed

The sewer network in Melbourne’s CBD was constructed over 100 years ago. Victoria in Future (2016) forecasts growth of approximately 60,000 new apartments in the CBD over the next 35 years, which includes approximately 14,000 apartments in the Spencer Street area.

To make sure we can continue to deliver a safe and reliable sewage service to people living and working in the CBD, it is essential to increase the capacity of the sewer network to support this growth. This is being done through the installation of a second sewer pipe along Spencer Street.

The works will involve the installation of a 1.4 metre diameter pipeline using a tunnel boring machine. The tunnel boring method will minimise the above ground impacts and reduce the need to dig an open trench along Spencer Street.

Some surface works will still be required and work sites and traffic alterations will be established along the length of the works and remain in place for the duration of the project.

Project impacts

For the safety of pedestrians and workers, we will be closing sections of Spencer Street as works are undertaken.

Access to residential and business properties, as well as underground carparks, will be maintained.

We will remain in contact with Vic Roads and City of Melbourne to keep motorists, businesses and residents informed of our scheduled works.

There will be no disruption to water or sewer services, and it is not anticipated that there will be disruption to the tram network.
