Components of the Water Balance and How Their Uncertainty Affects Performance Indicators Tom Crowder

Understanding and managing uncertainty within the water balance is essential for accurate performance assessment and effective water loss management. In this webinar, we’ll explore how different components of the water balance influence key performance indicators and how varying approaches can enhance reliability and confidence in results. • Learn how a UK water balance for a large water company can be converted into the IWA format, uncovering insights and the practical benefits of alignment. • Discover how to use the IWA Water Loss Specialist Group’s recommended method to evaluate the reliability of the water balance through confidence intervals. • See how the UK methodology applies maximum likelihood estimation to reconcile top-down and bottom-up balances within the IWA framework. • Examine how uncertainty impacts water loss performance indicators and interpretation of results. • Take a deeper dive into uncertainty analysis through real-world results from meter verifications and measurements of operational use.
