Doreen to Diamond Creek Sewerage Project

We are constructing new sewerage infrastructure in Doreen, Yarrambat and Diamond Creek to ensure the reliability of the sewerage system, cater for growth in Melbourne’s northern suburbs, and reduce the likelihood of sewage spilling into the environment during heavy rain events.

Project details

The project involves constructing a new 10-kilometre-long section of sewer pipe, and 18 new sewer manholes, within parkland and road reserves in the Doreen, Yarrambat and Diamond Creek areas.

Building the underground sewer pipe will involve our contractor, MFJ Constructions, upgrading or replacing an existing sewer pipe, and construction will begin at the northern end of the alignment, in the Plenty Gorge Parklands.

Construction details

MFJ Constructions will be working in some public parkland and along-side of local streets including:

  • Yan Yean Road (between Yarrambat Park and Ironbark Road)
  • Ironbark Road (between Yan Yean Road and Murray Road)
  • Murray Road (full length, from Ironbark Road in the north to the south)
  • Ironbark Road (between Murray Road’s southern end and Collins Street)
  • Collins Street (between Ironbark Road and crossing Main Street)
  • Hyde Street (between Main Road and Diamond Street)
  • Diamond Street / Watkins Street (between Hyde Street and Campbell Street Reserve).

Project timeline

Construction is expected to begin in September 2018, and is scheduled to be completed in mid-2020, subject to good weather and ground conditions.

Construction hours will be available closer to the start of works. 

Protecting the environment

By undertaking this project, Yarra Valley Water is protecting the local environment and waterways by reducing the likelihood of sewage spills during heavy rainfall events. However, it is equally important to protect the local environment, waterways and wetland during construction.

We have completed extensive environmental investigations to choose the best construction methods and reduce environmental impacts during construction. To reduce the impact of our works on established trees and the environment, and to avoid disturbing areas where aboriginal artefacts have been discovered, most of the new pipe will be constructed by using a machine to bore a tunnel under the surface, and then pushing lengths of pipe into the underground tunnel.

Watch how we build pipes by drilling underground.

Community impacts

These works will not affect water, recycled water and sewerage services in the area.

Despite our efforts to minimise the impacts of these works on the local community, people will at times notice construction noise, dust, and traffic disruptions. A Council-approved traffic management plan will be in effect to ensure workers, pedestrians, cyclists and motorists are safe.

Due to the depth at which the new pipe will be laid, and the high-pressure levels within the pipe itself, the new sewer pipe is not suitable for nearby properties to connect to for a sewerage service.
