Work has begun on a new $8.5 million sewer main, part of a $16 million upgrade of the Queenscliff / Point Lonsdale sewerage system.
The pipeline is being bored underground to minimise disruption.
The 4.3 kilometre pipeline will connect a new pumping station on Shell Road, west of Point Lonsdale, to an existing pumping station on Bonnyvale Road, Ocean Grove.
The new infrastucture will increase the capacity and reliability of the system, and meet expected population growth forthe next 40 years.
Work is expected to be completed in November.
This project is being delivered by the Barwon Water Alliance.
