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, though short access delays may be experienced. 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
Crews will be working for up to four nights from Sunday 4 May to Wednesday 7 May 2025 between 6pm and 6am, assuming the weather is fine and there are no major issues.
Temporary lane closures and detours will be in place during the night work, with one lane remaining open on Edith Street under the direction of traffic control. Please follow the direction of traffic controllers and signs.Learn more about work at the intersection of Platt and Edith Streets.
Platt and Bridge Street intersection
Work at the intersection of Platt and Bridge Streets from Monday 14 April to Wednesday 16 April could not be completed as planned due to challenging and complex site conditions. Crews will return to complete this work at a later date (to be confirmed closer to the time).
During this work, one lane on Platt Street, between Bridge and Alfred Streets, will not be temporarily closed with one lane open under traffic control. Detours are also in place.
Platt and Ada Street intersection
We expect to be working at the intersection of Platt and Ada Street for one week from late April 2025 and returning for three to five days from mid-May to complete the tie-ins of the newly relined main to our water network. We will confirm these dates closer to the time
One lane will be open under traffic control on this area.
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.
