Yorkshire Water – Implementing real-time network event detection to detect potential supply interruptions
A successful real-world trial of our groundbreaking eVader software
Artesia developed a method to make use of small area fast logging to quantify household consumption in each area, and then use a weather demand model to estimate each area’s monthly measured household consumption. This was thencorrected for meter under-registration. The data analysis process from data collection, QA, statistical analysis, modelling, and extrapolation to WRZ and company level has been developed into an online application to allow Severn Trent to calculate their unmeasured PCC in-house on a regular basis. The application provides Severn Trent Water with the ability to compute unmeasured night use for different regions and time periods, with the reassurance that the method has been fully audited and conforms to best practice.
Severn Trent have now asked Artesia to develop a similar set of small area monitors in their Hafren Dyfrdwy area in Wales for assessing their night use and unmeasured household consumption and integrate these with their individual household monitor in this area.
The Severn Trent area consumption monitor has successfully been reporting unmeasured per capita consumption (PCC) for the past few years allowing Severn Trent to report a robust PCC value in its water balance. The completion of the Hafren Dyfrdwy area monitor will allow Severn Trent to report PCC for its whole area in line with regulatory requirements throughout AMP7.
