Site investigations complete

Melbourne Water has now completed site investigations as part of the planning for the West Footscray to Yarraville Water Main Renewal.

Works for this stage included:

  • Locating underground services using non-destructive digging methods.
  • Drilling small holes to understand existing ground conditions and groundwater levels.
  • Visual inspections and data gathering by specialist contractors and consultants.

This information will assist in our detailed planning for the project.

Next steps

Between mid to late 2017, we will put the project out to tender to pick a preferred construction partner who will complete the works on Melbourne Water's behalf.

A preferred construction partner will be chosen by late 2017.

What is happening?

Work to renew the M102 water main will involve:

  • Constructing a new 900mm diameter water main through approximately two kilometres of local streets located between Paramount Road, West Footscray and Williamstown Road, Yarraville.
  • Reinstating the area as close as possible to pre-construction condition.
  • Decommissioning the existing 80 year old M102 water main that runs under Somerville Road.

Construction works are expected to start in early 2018 and will take approximately 12 months to complete, weather permitting.

The M102 water main has been in operation for over 80 years and is a critical part of Melbourne's water supply network, supplying the areas of Footscray Altona and Werribee.

Recent inspections of the existing water main have revealed that the pipeline is at the end of its operational life and needs to be upgraded to meet Melbourne Water’s service standards and to secure a reliable water supply for the growing west.

To date, Melbourne Water has completed three separate projects to renew 13 kilometres of the 15 kilometre M102 pipeline. The West Footscray to Yarraville Water Main Renewal Project will involve renewing the last two kilometre section of this pipeline between Paramount Road, West Footscray and Williamstown Road, Yarraville.

Managing impacts

Like any major project, there will be impacts associated with the renewal of the M102 water main. We are working closely with Maribyrnong City Council, VicRoads and the local community to manage these impacts.

Dig, Lay, Bury methodology with reinstatement taking place progressively as the pipes are installed. The work area will be continuously moving so that the works will only be at any one location for a short period before moving to the next section.

As majority of the works will take place in residential streets there will be some temporary changes to local traffic, parking and access. A traffic management strategy will be prepared to manage these impacts. We will also notify residents and businesses in advance of the expected changes to traffic and driveway access.

There will be noise and dust associated with the construction works. We will work closely with our appointed contractor to minimise these impacts, especially when working close to properties.
