New Werribee Aqueduct
A $24 million project to replace infrastructure crucial to Melbourne's sewage system is nearing completion in Werribee.
The 50 year old Werribee Aqueduct, which takes waste water from Melbourne to the Western Treatment Plant, has reached the end of its life and is being replaced by a new aqueduct being built alongside it.
Melbourne Water spokesman, Phil Corluka, said the covered aqueduct carries up to 60% of Melbourne's sewage to the Western Treatment Plant and the upgrade would ensure it can meet increased flows as the city grows.
"After 18 months of construction, we're almost ready to link the new aqueduct up to the existing sewer system, which will present some engineering and timing challenges," Mr Corluka said.
"The existing sewer system will be temporarily shut down on several occasions between mid-July and mid-August to stop sewage flows and enable redirection works to take place.
"These aqueducts don't normally generate any odour because they're covered, but we will have to take the cover off for limited periods as part of our works, so people may notice some odour.
"The construction activities will also require extended work hours and night lighting."
Mr Corluka said the works are being conducted over intermittent periods over 3 to 4 weeks to minimise any potential impacts on the community.
The new aqueduct will be 5.4 metres in both height and width.
The aqueduct has also been designed as a pedestrian and bicycle bridge to help connect existing and planned shared paths, parks and residential developments in the area.
A nearby heritage listed red brick aqueduct built in the 1890s will remain in place as an important part of Melbourne's history.
The new project is being delivered by the Pipelines Alliance – a partnership between Melbourne Water, Fulton Hogan, Jaydo Construction, and GHD.
This project is part of a major five year program of works to improve Melbourne's sewerage and drainage systems.
