Central Intervention Methods for Combating Real and Apparent Water Losses in Distribution Systems

According to the International Water Association (IWA), water losses in drinking water distribution networks result in environmental problems, damage to infrastructure, and unnecessary economic expenses. The objective of the present study is to conduct a literature review of central intervention methods for the reduction of water losses in distribution networks. A qualitative analysis of 250 documents was carried out, selecting 22 to identify effective methods to reduce water losses, highlighting that real losses represent 46% and apparent losses 22%. Also analyzing 136 case studies, it was observed that pressure control is the most efficient method to manage non-revenue water, and that combining different methods is an effective strategy to reduce costs. In addition, leakage prevention and analysis indicators are widely used, with 43% use in the management of apparent losses.
