Belmont Water Mains

We are planning to build two new water mains to distribute the treated water from the planned Belmont Desalination Plant to our customers and network.

These water mains will provide additional drinking water to eastern Lake Macquarie communities as they grow into the future and increase water security within the wider network during drought conditions.

The new water mains will connect the Belmont Desalination Plant into two existing trunk water mains in Belmont South and Jewells:

  • Southern: connection from the desalination plant to the water main at the intersection of Hudson Street and Williams Street, Belmont South
  • Northern: connection to the water main north of the Pacific Highway on Murray Street, Jewells.

The southern water main will also allow us to provide water to the desalination plant while under construction.

Project benefits

This project is part of Hunter Water’s program to ensure our region has a sustainable and resilient water system, both now and for the future.

The new water mains and associated infrastructure is a significant investment so that we can:

  • provide a safe, reliable and efficient water supply to the Eastern Lake Macquarie community while providing for growth beyond 2035
  • transfer drinking water from the proposed Belmont desalination plant to our customers and network.

Project timeline

Our contractor Diona is now finished the southern water main works. The northern water main project is due to start in mid 2025 and should take up to 18 months to complete, assuming the weather is fine and there are no major issues.

Construction impacts – northern connection

The work will start on the Kalaroo Road fire trail in Belmont Wetlands State Park and works towards Murray Street, Jewells.

The construction is predominantly on the side of the road and road access will be maintained throughout. Residents in Wommara Avenue, Fencott Drive, Ntaba Road and Murray Street will be kept up to date with any temporary impacts to driveway entries and street access as construction progresses.

During construction of the watermain local residents will notice:

  • additional vehicles and machinery in the area
  • construction noise
  • changes to traffic arrangements.

Resident’s water supply will be maintained for the duration of the work, with an outage expected during the connection process. We will notify properties affected by this ahead of the outage.
