This research examined mechanisms by which leakage is affected by climate extremes such as cold weather and soil movement. The associated increased stress exerted on underground infrastructure, following prolonged periods of wet and dry weather plus geographic variations and the influence of pipe materials was also considered.
The project identified seasonal variations in leakage detection performance, for example, due to high numbers of reported leaks, adverse weather conditions for leakage detection, etc which may lead to apparent increases in background leakage.
WRc and the centre for Civil and Computational Engineering at the University of Wales Swansea undertook the research for UK Water Industry Research (UKWIR).
- Enable the industry to manage risks on leakage associated with weather variations and to manage related operations / planning issues
- Allow informed discussion between the Utilities and Regulators about anomalies in leakage caused by changes in the weather.
