Air Scouring of Mains Pipes Commences

The first step toward cleaner water was taken yesterday with Burdekin Shire Council workers starting to clean out mains water pipes on Old Home Hill Road.

Council Operations Manager Wayne Saldumbide said the first trials of the new specialised pipe-cleaning equipment were successful in dislodging deposits which had built up in the distribution and reticulation mains.

“We are very pleased with the first trials of the new AirScour equipment and Council will now move forward with cleaning those areas most affected by discoloured water,” he said.

“This new process uses pressurised air and water to remove any built-up deposits on the pipe walls. Any deposits dislodged from the pipes are captured in a filter bag at the end flush site.

“Air scouring uses 60 per cent less water than traditional flushing and allows isolated sections of the mains infrastructure to be treated, which minimises the amount of time residents are without water supply.”

Mr Saldumbide said the AirScour process would address deposits in the mains pipes and new filters being designed for the South Ayr Water Treatment Plant would address iron and manganese discolouration issues in the water.

Residents would receive notification in their letterbox a week prior to scouring work being done on water pipes in their street.

The water supply will be disconnected at each household meter in the section being treated to ensure no deposits from the scouring process enter household supply.

Scouring works will be conducted between 8.45am and 3.30pm to avoid disruption to working people and parents with school-aged children.

Brandon, Rossiters Hill and South Ayr will be the initial target areas to be treated by the works.
