New technology rolling out for sewer inspections

Melbourne Water is introducing newly developed long-range CCTV camera technology to improve sewer inspections across the entire Melbourne network.

Melbourne Water is introducing newly developed long-range CCTV camera technology to improve sewer inspections across the entire Melbourne network.

The technology will enable inspections of up to 4 kilometres along large trunk sewers (2m – 4.5m in diameter). This will boost capability in the assessment and maintenance process.

Melbourne Water General Manager Asset Management Services Tim Wood said the new long-range CCTV camera unit will help Melbourne Water continue its important work to provide the community with a safe and reliable sewerage service now and into the future.

“Melbourne Water removes and treats most of Melbourne’s sewage. Ensuring the system operates at optimal levels is vital,” Mr Wood said.

“We are pleased to be embracing new technology which will provide advanced data on the condition of the sewer and the environment within it compared to just collecting visual images from conventional systems. This data will help us determine the best and most cost-effective way to look after it.

“Maintaining a quality sewerage service protects public health and the environment. In Melbourne, a safe, clean and healthy environment is essential to our way of life.”

Five manhole covers in Werribee and four in the southeast are being upgraded as part of this project to be large enough for the long-range CCTV unit to be lowered in.

Melbourne Water aims to minimise disruption to local communities and businesses during sewer inspections and associated works. However, people may notice general construction noise, some odour when manhole lids are opened and changed traffic and pedestrian conditions.

The project is scheduled for completion later this year. Once complete, the long-range CCTV camera unit will operate in approximately one-quarter (100 kilometres) of the sewer network.
