A new project is exploring how recycled water could help irrigate some of Melbourne’s most important parks and gardens, supporting a more sustainable and climate‑resilient future.
The study will look at using recycled water from South East Water’s Fishermans Bend network for places like Royal Botanic Gardens Victoria, Government House and City of Melbourne parklands.
Many of these green spaces rely on drinking water for irrigation, especially during dry periods. With less rainfall and more pressure on water supplies, this project aims to reduce drinking water use and keep parks healthy and green.
Fishermans Bend is Australia’s largest urban renewal project and will include a new water recycling plant and network to supply high-quality recycled water across the precinct.
Recycled water will be produced by treating wastewater to a high standard and supplied through a dedicated network of pipes to homes, businesses and green spaces like parks and gardens.
This system is designed to:
- support drought‑resilient green spaces
- reduce demand on drinking water
- help create a more climate‑resilient community.
This study will:
- look at how water could be delivered to parks
- identify specific water quality requirements for the plants and gardens in the scheme
- estimate costs and infrastructure needs
- work with key stakeholders to understand their needs.
The project includes major inner-Melbourne sites such as:
- Royal Botanic Gardens
- Kings Domain and Alexandra Gardens
- Government House grounds
- Fawkner Park and nearby open spaces.
This project is supported by the Integrated Water Management (IWM) Grants Program, which funds projects that make better use of all water sources — including recycled water, stormwater and rainwater.
The program helps improve water security, support greener spaces and build resilience to climate change across Victoria.
