Platt Street Water Main Remediation

We're upgrading the water main that runs under Platt Street in Waratah, between the Calvary Mater Newcastle and Ada Street. This work will help ensure efficient performance of the water network in this area for years to come.

What you need to know

  • We’re pleased to let you know that the major work to replace the watermain next to the Calvary Mater Newcastle is all but finished and the road is open. Intermittent traffic control may be in place to ensure finishing works can be completed safely.
  • From Monday 7 July, we’ll be cleaning and testing the new watermain. You won’t see many workers in the area during these activities.
  • Driveway access to the Reservoir Staff Car Park and the Fulton Hogan site compound will not be available from 8pm Friday 11 July until 5am Monday 14 July 2025.
  • From Monday 14 July, we’ll be connecting the new watermain into the network and carrying out restoration works along the remainder of the project area (between the hospital and Ada Street).

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).

Major work is now complete, and for the next two weeks we will be testing the new watermain and completing restoration and other minor finishing works.

How this will affect you

Traffic changes

Until Friday 18 July 2025, intermittent traffic control may be in place on Platt Street, between the Calvary Mater Newcastle and Ada Street, to ensure testing, restoration and other minor finishing works can be completed safely.

Driveway access to the Reservoir Staff Car Park and the Fulton Hogan site compound will not be available from 8pm Friday 11 July until 5am Monday 14 July 2025.

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.

Our aim is to minimise inconvenience to you, and we thank you for your patience during this work.
