Coal mine plans to get wetland flowing again

Restoring a wetland on the property of a Free State colliery holds the promise of benefiting not just the mine but the braoder environment, including biodiversity and surface water resources in the area.

According to Dr Simon Lorenz, principal hydrologist, SRK Consulting, the mine requested advise on remediating a wetland that had dried out - mainly due to a large trench previously exvacated through the wetland.

"Once you dig a ditch in a wetland, the water drains into that space and quickly flows away. This drops the wetland's water table and the fground dries out" explains Lorentz.
