Rottnest directional drilling project continues

The contractor was commissioned to deliver a new DN180 mm HDPE PN16 brine pipeline from the existing connection at the desalination plant to an outfall at Point Clune.

All potable water on the island is produced by desalination, with the reject water from the desalination trains discharged via the existing 90 mm PE pipeline.

In a social media post, DM Civil shared images from the project and said the new pipeline is being constructed using trenchless technology.

“The new DN180 HDPE pipeline is being constructed using directional drilling methodology as the majority of the pipeline will be below ground through the coastal limestone,” the company said.

“Approximately 550 m of pipeline is being constructed to assist with increasing the freshwater capacity on the island.”
