Experience the Western Treatment Plant at Werribee, and discover the historical and environmental importance of this fascinating site. The Western Treatment Plant was added to the Victorian Heritage Register in 2021, recognising its historical, archaeological and technical significance. The historic Western Treatment Plant in Werribee is a world leader in environmentally-friendly sewage treatment, and one of Victoria’s most unlikely hidden treasures.
Roughly the size of Phillip Island (covering an area roughly from Avalon Airport to Werribee Open Zoo), the vast site is home to more than just sewage treatment facilities – doubling as a working farm and internationally-recognised bird habitat. Here, agriculture and biodiversity meet resource recovery, education and ecotourism, supporting Melbourne’s renowned liveability.
The Western Treatment Plant’s variety of natural habitats provide a refuge for wildlife, including some of the world’s rarest bird and frog species – such as the critically-endangered orange-bellied parrot and growling grass frog. In 1983, the site was declared an internationally-significant wetland for waterfowl under the Ramsar Convention. More than 300 bird species have been recorded at the plant, attracted to the water and food in its permanent wetlands, making it one of Australia’s best places for birdwatching.
The Wadawurrung People lived on the land for thousands of years, making it a place of spiritual importance. The plant was also key to Melbourne’s early development – established in the early 1890s to combat the spread of disease, as open sewers emptied into rivers and bays.
Originally known as the Werribee Sewage Farm, the site included the township of Cocoroc (meaning ‘frog’), which housed sewage farm workers until the 1970s. Parts of it are still standing today, and now house our operations, administration and education facilities.
The RHSV has organised a tour of Melbourne’s Western Treatment Plant.
This is a really exciting opportunity.
We will have two brilliant guides for the day – firstly, whilst we drive from the RHSV to Cocoroc, historian Tony Dingle who has researched and written extensively about Melbourne’s water and sewerage will explain the historical importance of this treatment plant and then we’ll pick up a guide at the Treatment Plant to give us the contemporary information.
Tony Dingle teaches Economic History at Monash University. He has researched and published extensively in Australian and British history and his books include Settling, volume 2 of The Victorians (1984); Aboriginal Economy: Patterns of Experience (1988); and Vital Connections: Melbourne and its Board of Works (1991).
