Queensland Urban Utilities in partnership with the Water Services Association of Australia is adopting innovative sound technology to assess the condition of underground sewer pipes.

Queensland Urban Utilities spokesperson, Michelle Cull, said both the SL-RAT and Sewer-BATT were used to inspect 7km of pipeline in Brisbane last month.

“This new technology could provide us with another tool to quickly find blockages in our sewer network,” she said.

“The SL-RAT and Sewer-BATT assess the condition of a pipe by emitting a signal and recording the acoustic response, effectively ‘listening’ for any blockages or defects.

“There is no need for the operator to enter the maintenance hole or come into contact with wastewater.

“Queensland Urban Utilities is assessing the effectiveness of these technologies which have the potential to provide significant savings by streamlining the use of existing jet cleaning and CCTV technologies.”

Executive Director for the Water Services Association of Australia, Adam Lovell, said results are expected soon.

“The trial is expected to finish at the end of June with the final report to be completed by the end of July 2015.”

Four other water utilities are also participating in the trial.
