The paper will provide an overview of latest improvements in several aspects of analysis, prediction and validation of pressure management benefits. Six years ago, the publication by IWA Water Loss Task Force members of data showing significant reductions in mains and services bursts, from 112 Pressure Management Zones (PMZs) in 12 countries, helped to promote international interest in control of burst frequencies by pressure management. A conceptual explanation (‘the straw that breaks the camel’s back), coupled with calculation of simple separate Burst Frequency Indices (BFIs) for mains and services, has proved capable of rapidly identifying distribution zones where significant reductions in bursts could be expected, on mains and/or service connections, if pressure transients and/or ...
