The empirical method for the determination of apparent water losses, using the assessment of consumption patterns and the laboratory testing of water meters, is compared against alternative methods of comparative billing and meter change analyses for one of the largest water utilities in South Africa.

Assessing Non-Revenue Water and its Components: A Practical Approach
IWA Task Forces recently produced an international ‘best practice’ standard approach for Water Balance calculations, with definitions of all terms involved, as the essential first step in practical management of water losses.
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.

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.
