HV / LV Powerlines

Work packages totaling 90km of water and gas pipelines ranging in size from DN630 to DN110, below ground HV/ LV powerlines, isolation valves, golden welds, hot taps, road and waterway crossings, multiple LPD’s / HPV’s and connections into existing manifolds. The final works package, Narrabri Dewhurst South Project, included 4.6km DN315 HDPE Gas Flowline through the Pilliga State Forest.

The Narrabri project, although short in length and duration was very challenging due to the alignment of the pipeline being the middle of the Pilliga State Forrest, within an existing HDPE Water line corridor, with no new clearing allowed. The pipeline was subject to strict EIS conditions including minimising dust and erosion onsite. To manage the conditions an extensive erosion sediment control plan (ESCP) was designed and implemented.

Significant Controls needed from the EIS included:

Development of an extensive CEMP that showed the processes and controls for the job
Emergency management procedures showing responses to fire and flood
Stakeholder support and notification of works
Protester compliance training
Inductions including Environmental, Cultural Heritage requirements
