A temporary sewer pipe across the Anglesea River has been completed.
The above-ground bypass is transferring recycled water from Aireys Inlet and sewage from west Anglesea to the nearby Anglesea water reclamation plant until a new, permanent main is bored beneath the river bed.
The 300-metre pipe has been pulled across existing walking tracks and bridges from the west to the east side of the river between Coogoorah Park recreation reserve and Wray Street.
Pedestrian access to the tracks has been restored.
Barwon Water's General Manager Water Systems Carl Bicknell said the Barwon Water Alliance was assessing tenders for construction of the new pipeline.
"We expect a decision to be made in coming weeks, following which work will begin on the permanent pipeline," Mr Bicknell said.
"Our target is to complete this major project before Christmas."
Further updates will be provided on the Barwon Water website.
