What this report found

A regional scheme to collect, treat and re-use mine water in the Upper Olifants River Catchment has merit, with the mines best placed to start it through a dedicated mine water company that brings in the water services authorities. Water legislation supports the scheme provided the regulator allocates mine water as a resource. Viability rests on the tariffs mines and water users pay.

What this report found

Grazing pressure on the rehabilitated block ran at roughly three times the estimated carrying capacity. The sward was dominated by low quality grasses with a high proportion of bare ground and a raised erosion risk. Fenced exclosures over one year changed the abundance of a few species, but the vegetation showed no clear direction of recovery.
