Royal Park Wetland and Stormwater Harvesting System
City of Melbourne
The Royal Park stormwater harvesting project is one of Melbourne's most successful and well established stormwater harvesting projects, filtering urban runoff to supply irrigation water for the City of Melbourne’s heritage parks. E2Designlab staff contributed to concept and functional design of the scheme and completed construction supervision.
Stormwater is diverted from an open Melbourne Water stormwater drain, which collects water from a 187ha catchment area. The diversion structure, which also acts as a sediment trap, allows only low flows into the constructed wetland which is 0.8ha in size. The treated water then flows into a 12ML storage basin, which allows overflow into Moonee Ponds Creek. This storage space was supplemented in 2008 by a 5ML underground tank, situated below one of the sporting fields. To ensure the water is fit-for-purpose, it is treated with UV light and held in a distribution tank prior to use for irrigation of the neighbouring golf course, sports oval sand parkland. Two water hydrants are also located in an adjacent street to allow trucks to fill up and use the treated water for irrigation of streetscape features.
Water Sensitive City Outcomes:
- alternative water sources
- urban greening
- design and construction
