Working Wetlands Project (Royal Botanic Gardens)
About the project:
Project location: Melbourne, Victoria
Funding recipient: Royal Botanic Gardens Board
Total Australian Government funding: $1,980,000 (GST exclusive)
Water savings: up to 55 ML/yr
The project aims to reduce and eventually eliminate demand for potable water for irrigation in the Royal Botanic Gardens (RBG), Melbourne. Stormwater is diverted from adjacent streets and treated through constructed wetlands. The project will reduce demand for potable water used to irrigate the gardens by up to 55 megalitres per year (ML/yr), and maintain the ornamental lake, a central feature of the RBG Melbourne landscape.
- Use harvested stormwater to irrigate RBG Melbourne's landscapes and reduce the demand on potable water by 55 ML/yr
- Reduce nutrients entering the lake system and the Yarra River
- Improve water quality and amenity in the ornamental lake system, and
- Install photovoltaic cells to provide a renewable energy source for the project.
Construction of the project and the installation of photovoltaic cells to power the project were completed by June 2013.
Stormwater Harvesting and Reuse projects are funded by National Urban Water and Desalination Plan.
