Petrie Water Supply Upgrade

The Petrie Water Treatment Plant (operated by Seqwater) was built in the late 1950s and requires a substantial refurbishment to continue to safely supply customers. In 2011 it was determined that decommissioning the plant and connecting the scheme to the SEQ Water Grid was the most efficient solution.

Unitywater and Seqwater are working together on the Petrie Water Supply Upgrade. The project involves four construction projects:

  1. A pipeline to connect the Boundary Road Reservoir with the Northern Pipeline Interconnector
  2. A new pumping station and associated network configurations at the Petrie plant as well as pipework reconfigurations and decommissioning of the Kallangur Pumping Station
  3. A new water quality management facility at Boundary Road Reservoir
  4. Decommissioning of the Petrie Water Treatment Plant.

At the conclusion of this project about 100,000 residents in the Moreton Bay region will be connected to the South East Queensland Water Grid for the first time. People living in Dakabin, North Lakes, Mango Hill, Kallangur, Murrumba Downs, Griffin, Petrie, Lawnton and Strathpine will be supplied with drinking water primarily sourced from North Pine Water Treatment Plant.

    Saving Tips
  • Watering Tip #4

    Use the same water twice! Wash your car or boat on the lawn. This way your lawn gets watered while washing your car. For even greater water savings use a bucket of water instead of a hose.
