Trenchless to upgrade Waraba infrastructure

trenchless Waraba

Unitywater is set to use trenchless technology to start construction of the new wastewater network that will provide essential services to the new city of Waraba (formerly Caboolture West).

The first stage will see water and wastewater infrastructure delivered in partnership between Unitywater and six private development companies before 2025.

Horizontal directional drilling will be used at various points to minimise environmental and community impact.

Unitywater executive manager Mike Basterfield said the work is part of the utility’s $1.8 billion investment over the next five years in water and wastewater infrastructure.

“Positioned under the ground, water and wastewater networks aren’t often front of mind but they are essential to protecting public health, enabling economic growth and ensuring environmental sustainability,” Basterfield said.

“By working together with land developers and government to connect Waraba to our existing networks, we can sequence construction of these underpinning essentials for maximum efficiency, allowing the more visible aspects of a new land development to then begin taking shape.”

This first stage of wastewater network construction will see delivery of a new wastewater pumping station with a flow capacity of approximately 195L/s at a pressure of 350 kPa, 4km of wastewater rising main, and seven odour control units.

Unitywater’s construction delivery partners are Killard Infrastructure Pty Ltd and Tallai Project Group.
