Major sewer works planned for South Melbourne and Southbank

We're planning a major upgrade to the sewerage infrastructure in South Melbourne and Southbank to reduce the impact of future extreme weather events from climate change.

South East Water is in the planning stages of the South Melbourne Sewerage Capacity Upgrade (SMSC) which will:

Protect South Melbourne from extreme weather events

Increase the capacity of the local sewerage network, protecting the South Melbourne catchment from the impacts of future extreme weather events from climate change.

Meet South Melbourne's growing needs

Future proof the capacity of the sewerage network by helping to relieve surges or overflow from flooded pipes from future demand on the network.

Project stages

Due to the size of the project we've split it into four stages.

Stage 1

This stage of the upgrade has been completed, including construction of the new relief sewer and manholes along Stead Street and Palmerston Crescent on either side of Kings Way.

Stage 2

We’re looking to install new gravity sewer and rising mains running from City Road to connect into Stage 1, and to  add a pump station on Market Street (towards the end of Tope Street). While we have a preliminary route in mind, the final route will be determined once the project goes to tender and a final design prepared.

Stage 2 of SMSC will be delivered during our current Pricing Submission (2023 to 2028).

Stages 3 and 4

Stages 3 and 4 include long term plans that require significant future investigations and are anticipated to be delivered in future Pricing Submissions. We anticipate these stages to include the relining the existing Hanna Street Sewer that runs beneath Kings Way and, later still, duplicating the Wells Street Sewer.

The map below shows the proposed area of the project and its stages.

Geotechnical investigations

We completed geotechnical investigative works for stages 1 and 2 of the project in 2021. This will help us form the project's design by knowing what is already there and the construction teams will know what to expect when they start to dig.
