The 17 km pipe for Unitywater’s Wamuran Irrigation Scheme has hit the 13 km mark with the aid of horizontal directional drilling (HDD).
The scheme is designed to have a twofold effect – to deliver water security to farms in the Wamuran area, and to sustainably manage wastewater from the Caboolture South treatment plant.
1.7 km of the pipeline was laid using HDD, minimising environmental impact along those lengths.
Unitywater Executive Manager Sustainable Infrastructure Solutions Daniel Lambert said that the utility company is the first in Australia to commit to zero nutrients diverted or offset to waterways.
“This scheme will help us do just that,” he said. “It will divert 2.6 gigalitres of recycled water from the Caboolture River each year, saving 11 tonnes of nitrogen and 1.8 tonnes of phosphorous from entering the waterway.”
The 17 km pipe will ultimately tie in to a previously-constructed 5 km section.
“We’re really excited to be seeing such great progress with this project and remain committed to sustainable development in our region,” said Lambert.
