The BENCHLEAK model was developed to evaluate levels of leakage and non-revenue water in potable water distribution systems. The first study involved developing the model with a limited budget for checking the various data sets used to test the model. The main objective of the follow-on study was therefore to use the model to evaluate the levels of leakage in approximately 30 water utilities throughout South Africa.

Non-Revenue Water in South Africa
Municipal water use in South Africa has been under investigation for many years and the Department of Water Affairs and Forestry has been trying to establish the levels of wastage from all water supply systems countrywide.
LITERATURE REVIEW ON PRICING AND DEBT MANAGEMENT FOR WATER SERVICES
User fees, tariffs and property rates charged by the apartheid regime, had little relevance to the marginal cost of providing them. During the 1970s and 1980s, white suburbs and industries received per capita infrastructure investments on par with or even higher than most European and North American countries through heavy government subsidies.
Guidelines for Water Balance
The IWA developed the standard water balance to benchmark and evaluate the performance of water distribution systems and is being promoted across the world as best practice.
Sanflow User Guide
The SANFLOW model is designed to help water suppliers to determine the level of leakage in a particular zone metered area (ZMA) from the analysis of recorded minimum night flows.
A Guide to the Control of Water Losses in Pipe Networks
Water lost from a water supply distribution network can account for a considerable percentage of the total volume of water supplied. As this loss is paid for by consumers, a reduction in the amount of water lost could lead to a decrease in water tariffs, smaller pipe sizes and reduced water purification capacity and a delay in the need for increased storage.
