Anglesea sewer pipeline complete

A new sewer pipeline beneath the Anglesea River is fully operational after a major replacement project.

The project was completed on 22 December 2011, ahead of its Christmas deadline.

The pipeline was laid out and welded together along Bingley Parade, Anglesea, before being drawn through a pre-drilled tunnel beneath the Anglesea River.

The pipeline was fast-tracked to meet the demands of the summer tourist influx in Anglesea. Flows to the Anglesea treatment facility have already increased more than 4-fold in January.

We're now finalising the re-instatement of the construction site and contributing funds to a Surf Coast Shire project to lay new turf in the area.

Barwon Water would like to thank Anglesea residents for their cooperation, patience and understanding throughout this project.

 

Timeline of the project

August 2011: Barwon Water staff detected a leak in the original pipeline in August 2010 by checking logs of flows to the Anglesea Water Reclamation Plant. A tear was discovered in the pipeline, beneath the Anglesea River.

The pipe was shut down and sewerage was transported by truck to the treatment plant.

We considered a number of repair options but none proved feasible due to the difficult location of the leak and concern for the surrounding environment. The decision was made to replace the entire river crossing. The Barwon Water Alliance was engaged to undertake the work.

September 2011: A temporary above-ground pipe was laid through walking paths in Coogoorah Park.

November 2011: A drilling rig was set up on the west side of the river to tunnel 12.5 metres below its deepest point. Lengths of pipe were laid out on the east side and welded together to form a continuous 330 metre pipeline.

December 2011: The pipeline was drawn though the tunnel and connected. Work began on re-instatement of the site, including levelling and laying top-soil.
