Our Portfolio
Featured Projects
Strategic Large-Bore Water Main Installation (DN960)
A high-stakes utility project involving the supply and installation of 320 meters of DN960 MSCL pipeline. The project included specialized piling and structural encasement.
Nanima Pond Infrastructure Upgrade
A two-stage remediation and capacity expansion project for water storage ponds. The work focused on environmental compliance and structural stability of the storage basins.
Troy Gully Sewage Pump Station Upgrade (500 L/s)
A critical capacity upgrade for a major sewage pump station in the Dubbo region. The project modernized an aging facility to accommodate urban growth while significantly improving operational safety and environmental protection.
Design and Construction of White Cliff Water Treatment Plant
This project involved the provision of high-quality potable water to the White Cliff community through the implementation of advanced filtration and disinfection technologies. SNG managed the complex transition from raw water intake to a fully compliant drinking water facility.
Design and Construction of Cullen Bullen WWTP
SNG Engineering was engaged to deliver an end-to-end design and construction solution for the Cullen Bullen Wastewater Treatment Plant. The project focused on replacing aging infrastructure with a modern, automated system capable of meeting stringent environmental discharge standards while ensuring long-term operational reliability for the regional community.
