The Shire of Duaringa, in the Capricornia region of Queensland, is in the footprint of the Central Highlands Regional Council. Ten kilometres of 150mm pipeline transports water from the Dawson River to the treatment plant serving Duaringa. Over ten years, internal debris and accumulated weed growth compromised flow.

The terrain and access were difficult, so the pig had to travel the entire 10kms, pushing debris in front of it. A pig launcher was installed and two proving runs determined the condition of the pipeline. The working pig was able to remove all the weed, sludge, slime, and unexpected scale. Pipeline flows were increased by 60 percent and water quality was elevated. The pig launcher remains a permanent fixture for future maintenance.
