Werribee River Aqueduct Replacement

Melbourne Water has completed works to replace the sewer aqueduct that crosses the Werribee River, north of the Princes Freeway in Werribee (Melway Ref. 244 J1).

The project commenced in January 2009 and was completed in January 2011.

Constructing the new aqueduct

The new aqueduct measures 5.3 metres in height and 5.3 metres in width, and spans 70 metres across the Werribee River. The sewer aqueduct was constructed using incremental launching methodology, more commonly used in constructing road bridges. This innovative method of construction had the advantages of minimal environmental impact, safer working conditions and reduced project costs.

The footage below shows the structure being launched over the river in stages.

Why have we replaced the Werribee Aqueduct?

The Werribee Aqueduct transports up to 60% of Melbourne's sewage to the Western Treatment Plant in Werribee and is a critical asset in Melbourne's sewerage system. The current aqueduct has reached the end of its life and must be replaced.

This project is part of a major, five-year program of works to improve Melbourne's sewerage and drainage systems. The program is being delivered by the Pipelines Alliance, a partnership between Fulton Hogan, Jaydo Construction, GHD and Melbourne Water.
