Queensland Urban Utilities is investing $300,000 to upgrade sewer pipes in Gatton and Laidley.
Works have started to inspect, clean and reline more than 1.8km of sewer pipes, extending their life by up to 50 years.
Queensland Urban Utilities spokesperson Sally Prosser said crews would be using the latest trenchless technology to carry out the upgrade.
“The crews access the pipe through maintenance holes, so no open trenching is required, minimising impacts on the community and the environment,” Ms Prosser said.
“The relining process will involve pulling a soft PVC liner into the sewer, which is then formed into a solid circular pipe using heat and pressure.
“This project is part of our ongoing capital works program and demonstrates what goes on behind the scenes to ensure Lockyer Valley residents can keep their showers running and toilets flushing.”
