Portarlington WRP upgrade update and new brine pipeline construction commencing

19 September 2025

Portarlington Water Reclamation Plant upgrade: update

Works are progressing on the upgrade to the Portarlington WRP, with the new building slab, frame and roof complete, and excellent progress being made internally. We’ve also started work on the tank installation and water treatment infrastructure (see photos below).

New brine pipeline: construction commencing along Coatsworth Road

To effectively manage the brine (saltwater waste) from the new treatment plant, we’re constructing a new dedicated brine pipeline to transfer this saltwater waste into our existing sewerage network. It will transfer the waste into our existing sewerage network.

The brine pipeline will travel along Coatsworth Road, Scotchmans Road, Panorama Court and High Ridge Drive, as shown in the map below.

Construction of the pipeline will be commencing along Coatsworth Road in October 2025, from the Portarlington Water Reclamation Plant to Queenscliff Road, as shown in the map below.

Work will take place Monday to Friday, between 7am and 6pm. If Saturday work is required, this will take place between 7am and 1pm.

As part of this work, please note:

  • Work will take place in the nature strip on the northern side of Coatsworth Road.
  • There will be some changes to traffic conditions, including a partial lane closure on Coatsworth Road. Traffic management will be present on site to ensure the safe and efficient movement of pedestrians and vehicles.
  • There may be increased noise and dust. We will aim to minimise impacts to residents and businesses.
  • Some properties along Coatsworth Road will have limited driveway access for one day during the work while we dig a trench and lay the new brine pipeline. Impacted property owners will be notified seperately about the timing of these works. Driveway reinstatement will take place on the same day.
  • There will be no interruptions to your water and sewerage services as part of these works.


Work on the remaining pipeline length will take place in late 2025 and 2026.

We’ll continue engaging with local landowners over the coming months.
