Regional water and wastewater utility operator Unitywater says it is “still investigating” the cause of cracks in a sewer main which led to two separate sewage spills into the Noosa River just before Christmas last year.
As previously reported sewage spills on Monday 16 and Friday 20 December released effluent into the river in the vicinity of Lions Park.
A Unitywater spokesman this week said they “experienced two sewerage main breaks at Noosa on 16 and 20 December caused by two longitudinal cracks” in the pipework concerned.
“Breaks in water and sewerage pipes can happen for a number of reasons, including ground movement, changes in temperature, age and condition of the pipe and tree roots,” the spokesman said.
“In this instance we had to remove a Queensland Blue Gum tree in order to carry out repairs.
“We are still investigating the cause of the cracks in this pipe.”
The Queensland Department of Environment and Science (DES) earlier this month said it had also investigated the incidents but would take no enforcement action, after “confirming that effective mitigation measures” had been put in place at the time of the leaks.
