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.
