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.
Benchmarking leakage from water reticulation systems in South Africa 2004
The BENCHLEAK software was developed through the Water Research Commission to provide a simple yet pragmatic approach to the evaluation of leakage from potable water distribution systems. The model is used to assist water utilities to evaluate the levels of leakage and non-revenue water in their water distribution system.
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.
ASSESSMENT OF THE FEASIBILITY OF USING A DUAL WATER RETICULATION SYSTEM IN SOUTH AFRICA
Internationally, dual reticulation systems of diverse design specifications and configurations, conveying different non-potable water qualities for non-potable water requirements domestically and non-domestically, have been implemented.
