The Working for Wetlands funded the rehabilitation of the degraded Zaalklapspruit wetland, which receives mining-derived pollutants, while the project team determined if the wetland’s improved hydrological functioning enhanced its ability to reduce the levels of these pollutants. The results showed a significant reduction in most pollutants following rehabilitation and a substantial return on the initial capital investment of R1.7 million in rehabilitation.

The case study was published by the Water Research Commission (WRC) and is available to the public. Please note that the WRC requires members of the public to register with their knowledge hub in order to access any publications.
