M205 Carlton Water Main Renewal Project


This project is an essential upgrade to ensure safe and secure water supply for Carlton, Carlton North and the inner city for years to come.

The project includes installing 2.3km of new pipe along Canning Street, between Faraday Street and Park Street. Construction works started in August 2019 and are anticipated to be completed in mid-2020.

 Project update 18 August 2020

As we reach the final weeks of the project, the M205 team are working hard to complete the remaining works. To see what we will be working on, please see the information and map provided below.

Slip lining

The crew completed a ‘slip-line’ connection on Nicholson Street, between Pigdon Street and Brunswick Road. Slip lining is one of the oldest methods for trenchless rehabilitation, where by feeding a new smaller main pipe into an existing main pipe. These works were completed at night to minimise disruption to traffic.

Cross Connections

Located at the intersections of Nicholson Street and Park Street and Nicholson Street and Fenwick/Church Street, we will complete 2 cross connections to link the new water main on Canning Street into the existing network. These works will take up to two weeks to complete in each location, with work hours from 7am to 6pm weekdays.


With the new M205 water main installed on Canning Street, we can now start to decommission the 140-year-old retired main on Nicholson Street. The decommissioning works will take place in several locations along Nicholson Street and a small section on Barkly Street, and will involve filling the old main with grout. Decommissioning works will be completed at night and each decommissioning location will take two to three nights to complete. The maps below show the locations of this work.

We are working to reinstate any remaining areas on Canning Street such as, the cross overs at Lee Street, Curtain Street and Macpherson Street, some small sections of line marking, and the median strip near the Pigdon St roundabout.

Once all remaining works are complete, we will finish off with a full asphalt re-sheet of the remaining southbound lane of Canning Street between Park and Richardson streets and some sections of Park Street. Re-sheet works are expected to be completed by mid to late September. A small section of asphalt at the intersection of Canning Street and Richardson Street will be excluded from the asphalt re-sheet works, in preparation for the proposed upgrade works to be completed by the City of Yarra.

The Capital City Trail site will remain in place until all of the works are complete, to allow for required testing to be completed at this site. This site will then be reinstated with some minor updates, including the installation of a new water fountain, which is one of the community projects to be delivered to the Carlton and Carlton North area.

Current bike detour

Canning Street has been reopened to the community, however the detour will remain on Rathdowne Street until the asphalt re-sheet works have been completed and there is a seamless new road surface. Please see the map below for the current detour route, which takes rides south down Rathdowne Street, returning to Canning Street at Fenwick Street.

The detour around the Capital City Trail site will remain in place until the end of the works, for both cyclists and pedestrians. Please take care when riding and walking around the construction sites.

City West Water has established a Community Reference Group (CRG) in Carlton/Carlton North as a way to share information with the community about construction impacts, answer questions on construction activities, and contribute to the community project.

M205 Community Projects

City West Water has committed to delivering value to our customers through a community project, or community projects that will enhance the liveability of the area.

Where are the works?

The work will generally be carried out in the southbound lane of Canning Street, and a small section of Park Street and Nicholson Street. The works will be carried out in sections, the map below shows where we will be working during each stage of the project.

Will there be any impact on my water supply?

It is not expected that any service interruptions will occur, however should we need to interrupt your service, we will contact you beforehand.

What construction impacts can I expect?

There will be localised impacts such as noise, dust and vibrations. The construction team will manage noise from equipment such as generators and power tools by operating within Environment Protection Authority (EPA) decibel limits. Works will be limited to EPA guideline hours only.

Mesh fencing around the construction site will minimise dust generated by activities such as drilling and excavating. To assist with keeping the construction dust out of residences and buildings, we suggest that you keep your front windows and doors closed where possible during times of peak construction. Levels of vibrations will be monitored during these activities. However, if you have any concerns about the level of vibration you are experiencing, please contact the project team.

To avoid major impacts where Canning Street intersects with Elgin and Princes streets, we will be tunnelling underneath the road using a Micro Tunnelling Boring Machine (MTBM)

Why does CWW need to renew this water main?

The pipeline currently in Nicholson Street was installed almost 140 years ago and is nearing the end of its design life. The new pipe needs to be installed to ensure the community continues to receive clean drinking water. The new pipe will also be larger in diameter to meet the growing needs of the community into the future.

Why can’t CWW just fix the existing water main? Or just fix the parts that are leaking?

The current cast iron pipe was laid some 140 years ago has serviced the community well but has now deteriorated and has come to the end of its design life. This results in leaks and a high potential for failure which will have a huge impact on the community. The pipe also needs to be relocated as the upcoming installation of the Yarra Trams super stops on Nicholson Street will make it very hard to access the pipe for maintenance and repair.

The new pipe will be almost double in size and meet the current and future needs of a growing Melbourne for the next 140 years.

Who decided where the new pipe will go and how was this decision made?

City West Water engaged KBR to undertake an independently led analysis using a Multi Criteria Analysis (MCA) to review options based on many factors such as community, impacts, future needs, and available resources.

A MCA is a structured framework that investigates, analyses and suggests possible options to resolve complex decisions beyond looking at solutions based on monetary value.

As the MCA is independently led, the results of the analysis can provide confidence that all factors are considered in a methodological manner without bias. CWW also sought the input from subject matter experts such as local government, other water and infrastructure authorities and construction companies and arborists.

There is so much work going on in our area, why do you have to do this now?

We understand there is a lot of work happening in the local area. This is due to increases in development and population as well as aging infrastructure that needs upgrading. We need to do this project now due to the condition of the pipe to ensure you have access to clean drinking water. The pipe also needs to be relocated due to the upcoming installation of tram super stops along Nicholson Street, which will make it very hard to access the pipe for maintenance and repair.

What are the impacts to parking?

There will be parking changes along the alignment. When working in local streets residents are required to park their cars outside of this area to ensure a safe working zone. We will work with residents near work areas to maintain pedestrian access to private property and open up areas when it is safe to do so.

Residents who are required to relocate their car will be provided with direct notification. All parking permit holders within the Canning Street area will be able to park anywhere within their allocated zones during this time.

How will I safely move around the site?

Traffic diversions are necessary to ensure the safety of all road users. We understand this may cause an inconvenience to people who choose to ride their bikes on Canning Street and we appreciate your patience and cooperation during this time. Our Traffic Management Plans take into account all road users and will utilise a number of methods to ensure ease of access and safety. This includes information distribution through bicycle groups, signage, traffic management controllers and bicycle diversion plans if applicable.

Pedestrian access around the work site will be maintained throughout the project.

What if I ride to work via Canning Street?

If you use Canning Street to ride to work, you will have the option of:

  • Continuing to ride your bike on Canning Street and using the signed detour around the section closed for works, or;
  • Choosing an alternative street, such as Rathdowne, Drummond or Station Street to avoid the isolated temporary road closures along Canning St. This option will be better suited to bike riders when we are delivering works between Park and Princes Street from late 2019

Local closures and detours will only affect southbound riders heading towards the city. All northbound cyclists can continue to use Canning Street as usual normal.
