Client Information

Hunter Water Corporation

  • Duration: 9 months
  • Value: $3.2 million
  • Location: Windale / Gateshead, NSW
  • Project Details

Scope of Work

  • Construction of Gateshead No. 1 Wastewater Pump Station;
  • Upgrade of existing Windale No. 2 Wastewater Pump Station;
  • Construction of over 1.05km of 450mm and 600mm diameter DICL sewer rising main;
  • Construction of 200m of 450mm diameter GRP gravity main duplication;
  • Underbores for rising main under Pacific Highway and swamp schlerophyl forest;
  • Aerial crossing of existing creek and drainage culvert.

Significant Achievements

  • Highly planned shutdowns and very tight timeframes for sewer main connections, minimising disruption to HWC customers;
  • Extensive sheet piling works, and substantial structural concrete thrust blocks;
  • Overcame extremely difficult site access problems, as a large portion of the site was land-locked between the swamp schlerophyl forest, existing industrial properties and the Pacific Highway;
  • Two significant underbores, including an 85m long bore under the Pacific Highway which negotiated a complex network of existing services;
  • Excellent environmental performance with positive recognition from HWC for tree/vegetation management, erosion and sediment controls, dust suppression and maintaining water quality in adjacent creeks.
