Melbourne Water construction crews working on manhole cover

Melbourne Water will soon introduce new long range CCTV cameras in an effort to better monitor the city’s expansive sewer network.

The recently-developed technology will enable Melbourne Water to inspect up to 4km of large trunk sewers (measuring between 2m and 4.5m in width) increasing the utility’s ability to assess and maintain its critical infrastructure.

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 so ensuring the system is operating 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 south-east are being upgraded to accommodate the lowering of the long range CCTV unit.   

Melbourne Water said it will aim to minimise disruption to local communities and businesses during works, though admitted residents and commuters may notice general construction noise, some odour when manhole lids are opened and changed traffic and pedestrian conditions.  

The project is scheduled for completion by late 2022. Once complete, the long range CCTV camera unit will operate in approximately one quarter (100km) of the sewer network.
