Discover the Tonsley Wetlands Project.

Our SA team was engaged by CATCON (Civil & Allied Technical Construction), working with Renewal SA, to work on the Tonsley Wetlands landscaping. Renewal SA and CATCON’s project aimed to create a stormwater catchment from local drainage in Tonsley.

The project included treating the stormwater through the wetland filtration system before returning flows to local reserves. Doing this would encourage wildlife to return to a residential area and create a green infrastructure in a heavily built-up area.

Upgrades of Tonsley Train Station and the pre-existing bike track were also part of the works.
