The impact of reductions in leakage levels on reported and detected leak repair frequencies
This project investigated the impact of reducing leakage levels on the average frequencies of bursts and other identified leaks, including the proportions which are reported by the public and others, compared with those that are detected by Active Leakage Control. The project included analysis of data sets supplied by several water companies. There was no clear evidence in the data reviewed of an offsetting of increased detected leaks by fewer reported leaks as leakage is reduced. As a result the total number of leak repairs would be expected to increase. Water companies should factor the costs associated with additional detected leak repairs into the cost of leakage reductions. Water companies should also monitor the number of leak repairs in parallel to the leakage level to ensure accurate budgeting of the full costs of leakage reduction. Data should be collated centrally with access provided where required for analysis.
