Yorkshire Water – Implementing real-time network event detection to detect potential supply interruptions
A successful real-world trial of our groundbreaking eVader software
OFWATs PR19 guidance requires all water companies to move towards a consistent way of reporting leakage by the start of AMP7. Anglian Water currently calculate household night use (HHNU) from their individual household monitor (IHM), SODCON (Survey of domestic consumption). In order to improve the estimation of household night use, Anglian Water asked Artesia to help implement a new fast logging area monitor.
Artesia has since worked with Anglian Water to set up the fast logging monitor to the UKWIR best practice guidance including defining the correct sample size required, identifying suitable areas, developing the area specific calculations and implementing the process for reporting monthly household night use.
The monitor is statistically robust with a 90% confidence interval and representative of the company. This enables Anglian Water to report their night use robustly, and therefore report a more accurate leakage figure. It can also be developed to allow night use to be better predicted across Anglian Water’s DMAs, which will also improve leakage targeting and efficiency.
