Funding Council will embark on water main replacement projects at five locations within the CBD as part of the CBD Watermain Replacement Program 2023/24
Department Water and Wastewater
Status Under construction
Timeframe February 2024 and June 2024
Strategic purpose As water mains age, ensuring a consistent water supply for businesses and residents necessitates their replacement.

August 2024 update

All three planned water interruptions at Keen, Orion and Dawson Street are now complete. Keen Street and Orion Street. All services and meters are working off the new main. Concrete and asphalt restoration will be completed shortly. Dawson Street to Woodlark Street Testing, super chlorination and flushing is complete. Both mains are now active to allow service and water meter changeovers from old to new mains. Comprehensive trials were also completed on Woodlark and Dawson Street existing valves to ensure a smooth process for water main connections.

About the project

The project will involve:

  • installation of new water mains;
  • transfer of service connections; and
  • decommissioning of original mains.

The preferred construction method is horizontal directional drilling where feasible to minimise disruptions. This technique involves drilling the pipe into the ground in sections, with minimal excavation and backfilling using a small excavator.

If this method proves impractical at any location, residents and businesses will be duly informed to mitigate impacts.

Works will be located at:

  1. Dawson Street (Conway Street to McLennan Lane) - 96m, scheduled start: 28/02/24
  2. Dawson Street (Conway Street to Orion Street) - 937m, scheduled start: 01/03/24
  3. Keen & Orion Streets (Zadoc Street to Orion Street) - 330m, scheduled start: 13/03/24
  4. Woodlark Street (Dawson Street to Keen Street) - 206m, scheduled start: 21/03/24
  5. Zadoc Street (Molesworth Street to Keen Street) - 200m, scheduled start: 01/04/24

A laydown area for pipe delivery will be set up in the Harold Fredericks carpark opposite Oaks Oval, utilised until June 2024. 

Residents and businesses will receive a 14-day notice before works commence at each location.

Potential impacts of the project include:

  • increased noise and dust levels;
  • altered traffic conditions, including speed limit reductions and temporary lane closures. Traffic controllers will be present during construction hours;
  • temporary road closures or night works may occur in case of significant traffic interference;
  • temporary water supply interruptions, with affected parties notified at least 48 hours in advance;
  • slight water pressure reduction during temporary supply usage; and
  • temporary driveway access restrictions and footpath closures, with alternative access clearly indicated.

These projects are part of the Capital Works Water Pipelines initiatives, aimed at ensuring a secure and dependable water supply.
