M41 Pipeline - November Update

M41 water main renewal project

Early works

Works have started to replace a valve on the corner of Eades Street and Victoria Parade in East Melbourne. Replacing the valve will allow the M41 water main to be isolated in both the northern or southern sections and protect a City West Water main which supplies to hospitals along Victoria Parade. Works are expected to be finished by the end of November. 

Tender Phase

The M41 project is currently in the tender phase. Once a contractor is appointed at the end of this year, they will spend early 2018 refining the design of the M41 water main renewal, in consultation with stakeholders, and develop a detailed schedule for the project. Once the design, methodology and schedule detail is available Melbourne Water will provide more information, this includes speaking again with directly affected residents to let folks know what to expect and when. Construction of the new M41 water main is expected to begin in early to mid-2018. 


Community comments and feedback received have been provided to address issues that have been identified as important. These include:

  • resident parking,
  • construction impacts, particularly vibration, and
  • tree protection.

The project team at Melbourne Water welcomes additional feedback or comments via email M41@melbournewater.com.au or telephone 1800 316 713 (option 1).

Q&A with Melbourne Water on the M41 pipeline

On June 8 Liz and Peter from Melbourne Water had a chat in Edinburgh Gardens with a few of the folks from PFN, as part of community engagement on the new M41 Water Main Project.

Why was PFN meeting with Melbourne Water ?

The amazing response from our community to the M41 path Melbourne Water, through their feedback on the Melbourne Water M41 pipeline community consultation webpage. The Melbourne Water M41 Project Page

Melbourne Water are speaking to individuals and community groups all along the pipe-line path. Melbourne Water wanted to make it very clear minimising impact on all the trees along the new main is a key project goal.

Note : The interactive Google MyMap was done from meeting notes, it was not a map provided by Melbourne Water.

What is the new M41 pipe ? and why is Melbourne Water doing it ?

There is more background on the Melbourne Water webpage, but basically the M41 is the fresh water main from the Merri Creek to the MCG. It was installed nearly 100 years ago to supply the CBD, and surprise surprise, it needs to be upgraded to a new higher capacity main. The new one will be a pipe about 2m in diameter, carrying fresh water under high pressure.

How did Melbourne Water say they will protect the trees ?

The Melbourne Water plan is drawn up with each tree individually marked with the extent of its roots shown on the map as a no-go zone for digging. This approach complies with the AS 4590 Standard 2009.

The path of the new main has been chosen to avoid sewer mains, minimise disruption, and not damage trees. Two trees bordering the bike path will be moved, then put back after the pipe is laid. A link to an interactive google map showing the proposed path of the new main, drawn from my meeting notes, not supplied by Melbourne Water.

We were also told the project will include a "path maintenance window" of 18 months after the pipe is laid, where they will come back to check and fix any problems along the path which may show up after the works are done.

How long will the whole process take ?

We were told Melbourne Water expects the entire project end to end to take two years, with the construction period taking up to 18 months. This does not mean the park is a construction site for the whole time.

How much disruption ?

It was explained Melbourne Water have minimising disruption as a project principle when making decisions, and diversions will be put in place while paths or roads are affected. You can expect disruption to the places along the proposed path for between between a few days and a few months.

What happens next ?

Melbourne Water let us know they will be organising an open community information session before the project is finalised and goes out to tender. Melbourne Water said they will publicise the information session. PFN will put the details up on the facebook and website when we are notified.
