The changes in working patterns, water use demand and resource constraints are together having an impact on leakage figures. In some areas a rise in leakage is being seen - not thought to be due to a sudden increased prevalence of leaks occurring, but rather a paper-driven change due to the mechanisms that we use to estimate leakage. In some areas the pace of leak repairs has changed due to the need for social distancing, and resource constraints. However, coupled with this, the drop in non-household demand, and the use of fixed or inaccurate night use allowances have together resulted in changes to calculated leakage.
This study will assess the leakage estimation process, separate repairs-driven response from calculation-based response, and in turn provide an assessment of genuine leakage impact and recommendations for calculation improvements.
