摘要

Effective water resource governance in a water scarce environment such as South Africa is a strategic issue in national sustainable development priorities. Acid mine drainage (AMD) is one of the largest liabilities of the mining industry due to its inherent threat to water resources, human health and the environment. Against the background of evolving water governance in South Africa, three examples are explored to reflect the management of AMD in the upper Olifants River catchment. The Brugspruit Water Pollution Control Works shows the scale of historic liabilities faced by the state, as well as the challenge of effectively addressing AMD within a resource-poor environment. The Controlled Discharge Scheme takes advantage of the natural assimilative capacity of the upper Olifants River system during high flow conditions to effect the controlled discharge of AMD. The Emalahleni Water Reclamation Plant exemplifies the successful initiative by large and well-resourced mining houses to achieve engineered sustainable mine water management.
