A three tonne ‘ragberg’ has been pulled from Mackay City Council’s sewerage system.

It’s prompted pleas from the council to flush only the three p’s: pee, poo and (toilet) paper.

The solid waste material, dubbed a ‘ragberg’, was removed from the city’s No. 1 pump station at Sydney St this week.

A total of 12 loads of the ragberg were extracted in a four-hour operation, said Engineering and Commercial Infrastructure director Jason Devitt.

“When items such as paper towel and wet wipes are flushed down the toilet they become a solid which has the potential to choke the sewer network,” Mr Devitt said.

“When the system becomes choked with the matted solids it can overflow into the environment causing harm and also a risk to public health.”

Mr Devitt said a hydraulic grapple connected to a crane was used to remove the massive ragbergs from the sewer system.

“About 12 loads were removed to a skip bin and transferred to landfill, where all material besides the three Ps should end up,” Mr Devitt said.

“Council has cleared 620 chokes and partial chokes of various sizes in the sewer network in the last 12 months. This equates to a cost to ratepayers of about $250,000.

“It’s an expensive exercise,” he said.

Mr Devitt said 95 percent of the ragberg was wet wipes with the rest consisting of a variety of foreign objects.

“These items not only cause havoc in our sewer system but also can potentially affect the householder by causing internal blockages and broken pipes.

“This can result in sewage overflows into your property and can be costly to repair,” he said.

Residents are asked to bin the wipes and paper towel.
