Sunbury Recycled Water Plant Upgrade

We're upgrading the recycled water plant that services Sunbury & Diggers Rest.

Project snapshot

Town(s): Sunbury, 

Status: Planning

Cost: $53 million project over 10 years for upgrade, operation and other costs

Expected Completion Date: 2018

The Sunbury Recycled Water Plant (RWP) will undergo an extensive upgrade from 2016 to 2018 to increase its treatment capacity by 56% to 9.2 million litres per day.

The plant treats wastewater from Sunbury and Diggers Rest. These towns are among the highest growth areas in Victoria.

Opened in 1982, the Sunbury RWP - which is located at the end of Harker Street - has almost reached its treatment capacity.

Who will undertake the upgrade?

The RWP upgrade will be undertaken by Downer who were awarded the design, build and operate contract, announced by Minster for Climate Change, Environment and Water on 1 February 2016.

Downer commenced operation of the plant on 5 April 2016 with initial upgrade works due to commence later in the year.

The upgrade is the most significant capital works project in Western Water’s history. Despite significantly increasing its treatment capacity, the upgraded plant will only marginally increase in size as Downer’s innovative design will refurbish and modify as much of the existing plant as possible.

Other benefits of the Sunbury RWP upgrade include:

  • higher quality recycled water
  • better odour mitigation
  • improved energy consumption, and
  • job creation.

How will Western Water stay in touch?

Western Water will advise local residents and members of the project contact list and reference group about any potential works that may impact the local community.
