COVID-19 update: As an essential service provider, we are continuing construction and field work where it is safe to do so. We’re following up-to-date State health advice, including specific hygiene and social distancing protocols. Read more.

Melbourne Water is constructing the Holden Reservoir pipeline to supply residents and businesses in Melbourne’s developing outer-west region with a reliable and safe water supply. This project is one of the ways we're delivering on our commitment to  providing Melburnians with world-class water infrastructure.

Project updates

  • 8–11 May: Altered traffic conditions of Melton Highway's westbound lanes near Calder Park Drive
    To make use of present low traffic flows, we are expediting this section of pipeline works to minimise disruption to road users. 
    From the afternoon of 8 May to evening of 11 May, there will be changes to traffic westbound on Melton Highway after the intersection of Calder Park Drive, Sydenham. These works will be running 24 hours a day until complete. For details please view the traffic impacts section or community bulletin.
  • 6 April–end-May: Gourlay Road and The Parks intersection modification
    From 6 April to end-May, there will be changes to traffic at the intersection of Gourlay Road and The Parks along the Melton Highway, Hillside. For details please view the traffic impacts section.

What's happening and when

The new Holden Reservoir pipeline will be approximately three kilometres long and will travel along the centre road reserve of Melton Highway, westbound from Antionetta Way in Hillside and across to the north side of Sanctuary Road. See map below for pipeline location.

  • Complete - site investigation
  • Mid 2019 - site mobilisation
  • Mid 2019 - construction will commence and will take approximately 10 months to complete. Works will take place between Monday to Friday 7am to 6pm and Saturdays 7am to 6pm. We will notify you in advance if any works take place outside of these hours.
  • Mid 2020 - commissioning 

Construction impacts

Significant planning has gone into developing a pipeline alignment which meets water supply demands while reducing the environmental and community impacts. However, some construction impacts are unavoidable and will be managed by the project team in conjunction with Melton Council, VicRoads and the local community.

Traffic impacts

There will be changes to traffic conditions when we need to install the pipeline across the Melton Highway and intersecting roads.

The new pipeline will cross four intersections along Melton Highway, including:

  • Banchory Avenue
  • Gourlay Road
  • Royal Crescent
  • Sanctuary Road

Crossing these intersections will involve road closures. We will schedule these works to take place during off-peak periods, where possible. We will provide further written notification and erect signage in advance of any road closures or out of hours works.

Access to local residences and businesses will be maintained throughout construction.

Lane closures Melton highway – westbound: 8–11 May, 2020

We will be reducing flow across Melton Highway near Calder Park Drive to lay pipe for the Holden Pipeline Project. This crossover will affect the westbound lanes of the Melton Highway from the median strip to the footpath. Works will be limited to one or two lanes at a time and will involve digging a trench across the highway, laying pipe and then back filling and resurfacing the roadway.

  • Lanes will be closed from the afternoon Friday 8 May to evening of Monday 11 May 2020.
  • Work hours will be 24 hours per day (including night works).
  • Three traffic lanes will be merged into one lane. A speed limit of 40 km/h will be enforced through this area. Motorists may expect increased travel times during these works.
  • There will be signage and traffic management in the area to ensure safety and ease of traffic flow.
  • Footpaths and pedestrian access will remain unchanged.
  • Bike users will be directed by traffic management. 
  • Bus services and bus stops in this area will not be impacted by these works.
  • Access to and from the Melton Highway Service Road will remain open. 
  • Businesses in the area will continue to trade their current set hours.  

Please plan for increased travel times and consider alternative routes to avoid the construction zone.

Gourlay Road and The Parks intersection: 6 April to end-May, 2020

The intersection of Gourlay Road and The Parks along the Melton Highway, Hillside will be modified while works take place as part of the Holden Reservoir Pipeline Project. Work is planned to begin during the week beginning 6 April and be completed end-May 2020.

For the safety of motorists, pedestrians and our construction workers there will be:

  • No access for motorists through the intersection to Gourlay Road or The Parks
  • No right-hand turn into Gourlay Road or The Parks from Melton Highway

Please follow right-hand and U-turn detours that will be clearly displayed along Melton Highway.

Plan your trip and allow extra travel time as works progress through the area.

To help with planning your journey, please refer to the maps below.

Tree removal and offset planting

Melbourne Water has made every effort to reduce the number of trees that need to be removed as a result of the construction works. Unfortunately, some trees and vegetation will be removed in the centre and northern reserves of the Melton Highway. We are working closely with Melton City Council to develop an offset planting scheme specific to the area.

Future works

This project is the first phase of a three part overarching project. In the future, we will be constructing a new reservoir on vacant land on the north side of Melton Highway called the Holden Reservoir. This new pipeline will feed water into the reservoir from the Greenvale–Sydenham water transfer system. Finally, an outlet pipeline will be built.
