This particular section included gas and water gathering pipelines, along with the added complexity of installation of HV & FOC reticulation, often commingled within the trenches with the PE Gas & Water pipelines.

Pneumatic testing was progressively completed in five defined sections, allowing a sequenced handover of the asset to commence early gas extraction.

Completed on time and on budget, with zero defects, despite significant challenges of slow rock excavation and inclement weather.

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.
