Value: $1.2 million

Completed: October 2006

This $1.2M Project involved the construction of a 36m long truss bridge across a creek in Appin to support the 1200mm Macarthur Water Main which feeds Campbelltown.

The Macarthur Water Main is a privately owned main maintained by United Utilities for Sydney Water Corporation. The work was performed for BHP Billiton under the Project Management of the Department of Commerce.

The aqueduct (including compression fittings) replaced the main which was constructed through the creek bed to allow for localised mine subsidence.

Once the bridge and pipe work was installed, CLM was given a 12 hour shutdown period to complete two cut ins (one on either side of the creek). The cut in was completed successfully in under 10 hours.
