The recent drought, water restrictions, and interrupted water supply of late have highlighted the need for water supply security. For the Middelburg Chamber of Commerce & Industry, water security is one of the most fundamental cornerstones of our town’s prosperity. There is not a business that does not need water to operate optimally; this includes office parks, hairdressers, and manufacturers.
The Department of Water and Sanitation (DWS) published an Integrated Water Resource Plan (IWRP)for 2010. The report said that South Africa has enough water to stay in business and that there is no looming disaster and no cause for panic. However, some steps must be taken to avoid the severe and otherwise imminent risk of shortages in many areas. DWS said that significant investment in water conservation and water demand has to happen at a national level, as well as investment in groundwater exploration and use. Concerted input into managing water quality, and especially acid mine drainage and the pollution of rivers through under-performing wastewater treatment works were also priority areas.
Collieries have grown to such an extent in our area that they are generating more water than mines need for their operations. Excess water (Groundwater ingress), the poor quality of the water and the lack of assimilative capacity in the Olifants River to accept discharges of mine water, has led to the implementation of water treatment facilities. The Olifants Reconciliation Strategy proposed that acid mine water has to be desalinated before decanting into the river system.
The reports also mentioned that there should be a coordinated plan between Middelburg and Witbank. It was noted with disappointment that the desalinated water from South32 would not be pumped into the Middelburg system as they have only done a business case and the South32 management has not approved such an agreement.
The IWRP also stated that: “The water requirements of Steve Tshwete LM will exceed the 50-year yield of the Middelburg dam by 2012”. We cannot afford to only rely on rainwater to ensure our town’s prosperity.
