In a report, 'Benchmarking of Leakage from Water Reticulation Systems in South Africa', the Water Supply Commission states that the South African water supply industry is generally lagging behind best international practices with respect to leakage management in potable water distribution systems. And, if water supply systems are not maintained properly, due to a lack of resources, sheer incompetence or a lack of capacity, these will quickly deteriorate and the infrastructure leakage index will steadily increase to unacceptable levels, which is where South Africa is right now. According to the Department of Water and Sanitation, the current level of non-revenue water is estimated at 36.7%, of which 25.4% is considered to be losses through physical leakages.
