Melbourne Water is planning the construction of a new water treatment plant  at Mount Evelyn. The proposed new plant will increase the resilience of the nearby Silvan Reservoir Water Treatment Plant, which plays a vital role in providing Melbourne with safe drinking water.

Why this is important

The Silvan Reservoir Water Treatment Plant forms a critical part of Melbourne’s supply network, providing up to 50 per cent of Melbourne’s safe drinking water.

Through Melbourne Water’s water quality risk assessment process, we’ve identified the need to improve the resilience of the Silvan Reservoir Water Treatment Plant, particularly from instances of extreme weather events, to ensure continued supply of safe drinking water.

This project involves the construction of a new backup treatment plant located downstream from the Silvan Reservoir Water Treatment Plant, which will become active during scheduled maintenance or an unexpected situation occurring at the Silvan Reservoir Water Treatment Plant.

The proposed new Mount Evelyn Water Treatment Plant will improve the resilience of Melbourne’s water supply, despite increased demand across the network, while ensuring local amenity, environment and heritage are protected  throughout the delivery of this project.

What’s happening and when

Following community engagement in mid-2021, a planning permit was submitted in September 2021, and detailed designs will be developed in 2022.

What to expect

Significant planning is going into designing and developing the proposed Mount Evelyn Water Treatment Plant, to ensure it meets water quality requirements while reducing environmental and community impacts as much as possible.

Melbourne Water will continue to work with nearby residents, businesses and Yarra Ranges Council to mitigate any impacts throughout the planning, design and construction of the proposed Mount Evelyn Water Treatment Plant.

Once complete, the building will be approximately the size of a small private residence at 36 metres x 7 metres, and 7 metres high.

Traffic and pedestrian impacts

During construction, there will likely be some changed pedestrian and traffic conditions. We will provide advanced notice to residents and the community ahead of any changed pedestrian and traffic conditions.

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

Designated safe pedestrian access along the Melbourne Water pipe track will be maintained after construction. During construction periods, please follow the directions of signage and onsite crew.

Vegetation 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 need to be removed or trimmed.

Vegetation surveys indicate some vegetation will need to be removed or trimmed due to the constrained nature of the site, specifically:

  • Road location: in order for trucks to safely access the site, there is a minimum turning circle required, which pushes the road to the edge of the treed area to the north and west of the site.
  • Power lines: power cables currently across the project site will likely need to be relocated to allow safe access. This may require some vegetation removal to the south side of the site.

We are working to develop offset planting schemes specific to the area.
