The Bapsfontein dolomite water compartment, located east of Pretoria on the Delmas road, is being dewatered at an alarming rate and is resulting in widespread instability in the area in the form of sinkholes, depressions or cracks. Many boreholes in the area are drying up and this is depriving inhabitants of their source of potable water. The question that needs to be answered is : Why are a few users in the area authorised to pump more water from the aquifer than its sustainable yield?
