Glen Iris Wetland Redevelopment

The Glen Iris Wetlands project, part of the Lower Yarra Stormwater Action Plan, has improved the treatment of stormwater and created habitat for the foraging, breeding and sheltering of native animal and bird species.

The wetland system passively treats stormwater from the Hedgley Dene main drain to improve the quality of water that enters Gardiners Creek and ultimately the Yarra River. Treatment removes a range of pollutants contained in the water.

The Glen Iris Wetland now consists of two relatively deep ponds and a small pond interconnected by rock weirs and surrounded by vegetation.Native species have been planted throughout the wetlands and on the pond edges.

The stormwater treatment wetland and storage pond is now 5,345m² and removes approximately 12 percent of nitrogen and 21 percent of phosphorous from the water entering the wetlands from Hedgley Dene drain each year. Prior to this project, these pollutants would have directly entered Gardiners Creek.
