A $650 Million project to boost sewerage capacity in Melbourne’s north and protect the health of local waterways has been completed ahead of schedule and under budget.

Water Minister Peter Walsh today helped lower the final section of the last shaft cover of the Northern Sewerage Project, marking the culmination of four years of excavation and construction.

Mr. Walsh said the project, which has come in $135 Million under budget and six months ahead of schedule, provided significant public health and environmental benefits.

“The completion of the Northern Sewerage Project will virtually eliminate raw sewerage spills into Moonee Ponds and Merri creeks during extreme wet weather.” Mr. Walsh said.


“The project provides additional sewerage capacity for Melbourne for Melbourne’s fast growing northern suburbs including Epping and Craigieburn and will protect the downstream health of the Yarra River and Port Phillip Bay.”

Mr. Walsh said the Northern Sewerage Project was one of the largest and most ambitious sewerage tunneling projects ever undertaken in Australia.

The completed project includes 8 vertical access shafts and 12 km of underground tunnels from Coburg to Reservoir in the north and west to Pascoe Vale and Essendon.

Construction commenced in 2007, with tunneling and excavation methods selected to best minimise impacts on local residents and businesses.

Tunnel boring machines up to 100 metres long were used to bore through varying ground conditions ranging from soft Silurian period rock to basalt at depths of up to 64 metres.

“Local communities have dealt with a significant amount of disruption, but with the project now complete, about 100,000 homes will benefit.” Mr. Walsh said.

“The new sewer takes flow to the Werribee Treatment Plant and forms part of an extended network of sewer pipes stretching about 21,000 km and carrying in excess of 260 Billion litres of sewage to local and regional treatment plants each year.”

The Northern Sewerage Project is part of the metropolitan water businesses multi-billion infrastructure program paid for by water and sewerage bills. Melbourne Water and Yarra Valley Water delivered the project which was constructed by John Holland and designed and managed by SKM/Jacbos Associates and Aurecon.
