Preparations are underway for construction of a new sewer pipe beneath the Anglesea River.
Pipe delivery will begin this week and work sites on both sides of the river enlarged to accommodate a drilling machine, which will bore the permanent pipeline route under the river bed.
A second above-ground pipeline will also be installed alongside the existing temporary sewer bypass this week.
It will be used during boring to remove spoil.
Pedestrian access to walking tracks and bridges from the west to the east side of the river between Coogoorah Park recreation reserve and Wray Street will be closed from Wednesday for about a week during construction of the spoil line.
It will run alongside the temporary bypass, which is currently transferring recycled water from Aireys Inlet and sewage from west Anglesea to the Anglesea water reclamation plant. Both temporary pipelines will be removed once the new main is completed.
Barwon Water Managing Director Michael Malouf said work would be ramped up over the coming weeks. Changed traffic conditions would operate near the work sites.
"While there will be some inconvenience, we ask residents to be patient," Mr Malouf said.
"We are aiming to complete this important project before Christmas to ensure the infrastructure is in place before the peak holiday period," he said.
Further updates will be provided on our website and a community information bulletin will be issued prior to construction.
