Petrie Water Supply Upgrade - Unitywater and Seqwater
QLD WINNER 2018
The Petrie Water Supply Zone Upgrade connected 100,000 people to a new, more secure source of water, avoiding an expensive upgrade of an ageing treatment plant. The $16.5 million project comprised three major construction projects that were seamlessly integrated, connecting the scheme to the SEQ Water Grid while avoiding potentially major disruptions to the water supply.
 
Unitywater and Seqwater worked together to deliver this complex project which reversed the direction of flow in the scheme’s network hydraulics and changed the disinfection regime. The project was commissioned without disruption to customers and the old treatment plant turned off.
