About the work
An existing water main under Platt Street in Waratah, between the Calvary Mater Newcastle and Ada Street, needs to be upgraded.
Work will begin with replacement of around 100m of water main near the side entrance to the Calvary Mater Newcastle. This will involve closing one lane on Platt Street and progressively excavating the road to reveal and replace the existing water main. To ensure the water network continues to perform efficiently during the work, two temporary water mains will be installed on Platt Street, near the entrance to Reservoir Car Park.
The remainder of the water main on Platt Street, to Ada Street, will be relined. Relining allows us to remediate the water main without excavating the entire 400m length, however some excavation will need to take place at the intersections of Platt Street and Edith Street (nightwork), Bridge Street, and Ada Street so that the newly relined water main can be tied into the network. The liner will be assembled offsite and then pulled into place over two days. It will be placed into the existing water main through a pit near the side entry to the Calvary Mater Newcastle (launch pit) and pulled through to a pit at the intersection of Ada Street (receival pit).
All areas will be remediated and returned to their current condition once all water main work is finished.
The upgrade should take about 10 weeks to complete, assuming the weather is fine and there are no major issues.
How this will affect you
Traffic changes
There will be changes to local traffic movements, including lane closures and detours, and construction vehicles in and around Platt Street during the work. Please follow the directions of traffic controllers and signs. Delays are expected, please allow extra travel time.
Platt Street – next to Calvary Mater Newcastle
Temporary traffic changes are in place on Platt Street, next to the Calvary Mater Newcastle, to help ensure the work zone is safe. Platt Street has been reduced to one lane under traffic control, to allow for safe movement of construction vehicles and equipment.
Access to the Reservoir Staff Car Park and Fulton Hogan site compound, Secure Parking Station and other driveways in the area will be maintained, except for Saturday 31 May and Sunday 1 June 2025 when no access will be available. Please follow the directions of traffic controllers and signs.
These traffic arrangements will be in place for the duration of the project. Delays are expected and we encourage road users in the area to allow extra travel time.
Platt and Edith Street intersection
Initial night work at the intersection of Edith and Platt Streets is complete. Crews will return to the intersection to connect the newly relined watermain in a couple of weeks, dates will be confirmed closer to the time.
Platt and Bridge Street intersection
Interflow will be working at intersection of Platt and Bridge Streets from Monday 26 May to Saturday 7 June 2025.
The eastbound lane on Platt Street will be closed between Bridge and Alfred Streets. The southbound lane on Bridge Street, between Lorna and Platt Streets, will also be closed during this work. A bus stop opposite the Corpus Christi Primary School will be temporarily relocated to the front of 43 Platt Street while work is completed. Traffic control will be in place in the afternoons to help ensure children get to the bus stop safely.
Platt and Ada Street intersection
Work is underway at the intersection of Platt and Ada Street. We will aim to keep one lane open in each direction but there will be times when the road will be reduced to one lane under stop/go traffic control.
Noise, dust and vibration
At times we will use machinery and equipment that generate noise, dust, vibration and light. The noisiest activities including road cutting and excavation. We will make every effort to minimise the impacts, where possible, by:
- turning off machinery and vehicles when not in use
- using acoustic barriers where suitable
- positioning noisy equipment and lighting towers as far away as possible
- using non-tonal reversing beepers on all machinery
There will be no disruption to your water supply during this work.
Our aim is to minimise inconvenience to you, and we thank you for your patience during this work.
