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 3 June 2020
We have designed, built, tested and installed the cross connection to link the M205 750mm main on Canning Street into the Melbourne Water M160 1350mm main by the Capital City Trail on Park Street. Hosting an impressive excavation, spanning across more area than an average inner-city house block, the site is located on the Capital City Trail and will remain in place until the Pigdon St bore works are complete.
We are completing the final section of construction for stage 5 of the project, located on Canning Street around the Pigdon Street roundabout. The water main pipe will be installed by tunnelling underneath the roundabout using a micro-tunnel bore machine in order to avoid underground services and interruptions to east and westbound traffic, and to preserve the tree located in the roundabout.
Once finished, a full re-sheet of the southbound lane of Canning Street will be completed to leave a new surface completed with new line marking, including new bike land markings, for residents and road users. This will complete the works on Canning Street as the project moves over to Nicholson Street at the end of June. The project team are currently completing preliminary works in order to prepare for this next stage of works
Current detour route
For the safety of the southbound riders, detours will continue on Rathdowne Street. This is a small diversion, with Fenwick Street bringing riders back to Canning Street just a short distance south. The detour includes a short deviation to the Capital City Trail, with rhino matting installed to provide a safe alternative route. Please see the below detour map for more information on the current detour.
Our friendly traffic management team will be onsite to assist. Please take care when riding around the construction site.
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.
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.
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
- 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.
