Before European settlement, the Port River was fringed with intertidal wetlands. Some of these historic wetland areas have been restored for the purposes of managing and treating stormwater.

The constructed wetlands at Barker Inlet, Magazine Creek, and Schroder Park (adjacent to the Adbri Cement Plant) improve the water quality of stormwater discharging into the Port River and Barker Inlet and can also protect infrastructure by absorbing water during high tides and storm surges.

Constructed wetlands also restore other ecosystem services provided by naturally functioning wetlands such as wildlife habitat, attractive landscape features, and eco-tourism.
