Water Loss Management Summary Sheets: 3. Sectorising and Step Testing

Sectorising is the process of splitting a large water reticulation system into smaller zones which can be individually monitored to help in the identification of water losses and other water related problems. The process of sectorising is well known as a critical element of any water loss reduction programme and has long been regarded as the starting point of any comprehensive water demand management strategy.

Assessment of apparent losses due to meter inaccuracy – a comparative approach

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.

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.
