The Greening the Pipeline initiative aims to transform 27 kilometres of the heritage listed Main Outfall Sewer reserve into a linear parkland. Our vision is to create a vibrant space that will connect communities, and provide a unique place to meet, play and relax.

This project is being undertaken through a partnership between Melbourne Water, City West Water, Wyndham City Council, VicRoads and supported by Greening the West.


  • Improve health and wellbeing
  • Activate community sense of place
  • Enhance active transport links
  • Create water resilient open space.

Our inspiration:

New York has transformed an old railway into a public park that provides open space for the community, known as The Highline. We want to create a similar space in Melbourne along our historic pipeline.

Come along to the Community Park Launch!

What is the Main Outfall Sewer?

The Main Outfall Sewer (MOS) was built in the 1890s to improve the health of Melbourne. Running for 27 kilometres, from Millers Road in Brooklyn to the Western Treatment Plant, it formed a vital link in the sewerage system of Melbourne. For nearly 100 years it transferred the majority of Melbourne’s sewage for treatment. In 1993, the MOS was decommissioned following construction of the underground Western Trunk Sewer. In 2005, VicRoads built the Federation Trail for cyclists and pedestrians along the MOS reserve land. The MOS is a fine example of 19th century engineering and is protected under the Heritage Act 1995.

The pilot park - Williams Landing

Melbourne Water, with the help of Wyndham City Council, City West Water and VicRoads received a grant from the Victorian Government to revitalise the first section of the pipeline in Williams Landing, along a 100 metre section of the historic MOS reserve next to the Federation Trail. The Williams Landing parkland is the pilot park for the Greening the Pipeline initiative.
The park showcases the potential of the MOS in creating a green linear parkland that takes a more holistic approach to water management and enhances community liveability.

Stage one - Lawrie Emmins Reserve to Skeleton Creek 

In the next stage, the project will focus on creating a parkland between Lawrie Emmins Reserve and Skeleton Creek, Zone 5 on the map. The location has been chosen due to the close proximity of housing in the area and the need for additional green open spaces to support the new communities. Funding was sourced by project partners to engage the community to influence the design of this next stage. This valuable feedback will be fed into the proposed future design of the parkland. The pilot park in Williams Landing showcases the potential of the MOS reserve. We can use this space as a success story to apply for additional funding to progress the next stages of the project.

What’s next?

We will continue to source funding to bring this project to life. This is a long term project with potential for enhancing recreational, economic and tourism opportunities along the length of the pipeline

How can I provide feedback?

We want to involve the community every step of the way, and will offer opportunities for you to provide your input throughout the planning process. Check our website for the latest updates
