Wetlands - Melba (West Belconnen catchment)

Wetland, corner of Ginninderra Drive and Copland Drive, Melba

Two new wetlands beside the Canberra BMX Club in Melba will filter urban stormwater before it flows into Ginninderra Creek. Construction will be completed by the end of June 2019.

This wetland will remove over 49,000 kilograms of nitrogen, phosphorous and suspended sediment every year from urban stormwater destined from the Ginninderra Creek.

The project is one of three water quality infrastructure projects being built downstream of Lake Ginninderra. Another two wetlands near Croke Place in McKellar and the revegetation of a stormwater drain in Florey complete the set.

Rock armaments will protect the wetlands from periodic flooding.

Although a number of trees were removed to make way for the wetlands, extensive re-planting was undertaken.

The linked wetlands in Melba also include a sediment pond and an open gross pollutant trap. They have a combined surface area of about 9,200 square metres.

Design changes

During the final design phase, some changes were made to the original concept designs to accommodate services, community feedback and maximise water quality benefits.

  • Armaments were added to protect the wetlands from localised flooding.
  • An encircling pathway was removed for public safety and operational reasons that relate to the flood risk.
  • Collection and distribution pipes were reconfigured to reduce the impact on the existing waterway.
  • The gross pollutant trap was moved to an offline position.
  • A diversion weir was replaced by a culvert crossing for the access track.
  • The two access tracks proposed for community consultation has been replaced by a single track to minimise disturbance of the grass area and trees.
