Works on retarding basin commenced
We are planning to start work to complete landscaping works at Thornhill Park Retarding Basin and Wetland in early 2025. Thornhill Park retarding basin and wetlands reduces the risk of flooding to surrounding homes.
In Melbourne, rain and storms are part of everyday life. Floods are a natural part of our landscape and an essential part of the weather cycle. Melbourne Water manages more than 200 retarding basins. They are designed to reduce flooding by catching heavy rainfall which hold in a reserve of low-lying land. Once storm water is collected, it is naturally treated within this system prior to being slowly released back into the environment to follow the natural drainage lines into our creeks, rivers and eventually to the bay.
The Thornhill Park retarding basin will reduce flooding events and keep our community safe today, tomorrow and for generations to come.
In 2018 works to establish a retarding basin at Thornhill Park Estate were undertaken by the developer of the site. After the site was handed over to Melbourne Water to manage, it was determined a drainage channel needed to be constructed north of the Western Freeway. The new channel will help to maintain storm water flow towards nearby wetlands to ensure stable and consistent water levels in the retarding basin.
Landscaping works were deferred until the channel was constructed so that the water level of the retarding basin could be lowered to an appropriate and consistent level to allow for civil works to be completed and plants to establish effectively.
Landscaping works are expected to start in early 2025.
The works will be undertaken in two stages, firstly;
The retarding basin is located near Paynes Road and the Western Freeway and can be accessed from Wingfield Drive and Gilfillan Circuit in Thornhill Park.
