Factors Affecting Minimum Achieved Leakage
The Minimum Achieved Leakage (MAL) is the lowest level of leakage achieved over a specified period of time, under respective Active Leakage Control (ALC) policies. This report examines the relationship between MAL, calculated using a consistent methodology, and a range of physical and operational explanatory factors for 8 Water Service Providers (WSPs).
Predictive functions have been developed which estimate MAL at District Metered Area (DMA) level in response to explanatory factors. Nationally representative functions can be applied for a range of MAL frontiers for comparative purposes. Functions can be calibrated to WSPs for ‘gap filling’ where calculation of DMA MAL has not been possible, and to estimate future changes in MAL due to ageing, pressure management, asset renewal, DMA size, and reported and detected leak repair frequencies for customer and company-side assets. Functions can also be used to integrate ALC, pressure management and infrastructure renewal interactions within leakage economic modelling.
