Project Overview

To continue to deliver a safe and reliable sewerage service to people living, working and visiting Melbourne CBD, it is essential that we increase the capacity of the sewer network.

The Elizabeth Street Sewer Upgrade is Stage 3 of a four-stage strategy to install a second sewer network. We are constructing a new 700m sewer line under Elizabeth Street from Victoria Street to Lonsdale Street.

Construction will start in early to mid 2022 and take one year to complete.

The project to date

Stages 1 (Spencer St, 2018) and 2A (Lonsdale St, 2020) have been successfully completed.

Last year we undertook site investigations along the project area (below), and have been working closely with Melbourne City Council, Department of Transport, Emergency Services, Metro Tunnel Project, Yarra Trams and utility providers to reduce the project impacts as much as possible.

In November 2021 Rob Carr Pty Ltd and their design partner SMEC was appointed to finalise the design and undertake the construction.

Upcoming works

We will be undertaking further ground investigations, including service locating and geotechnical investigations, during May and June 2022 to inform the final sewer alignment and detailed design.
