Leakage Estimation from Night Flow Analysis

 
Price: £12  

Existing methods for providing leakage estimates for reporting purposes, using data from continuously monitored areas are reviewed. Analysis concentrated on night use allowances and 15 minutes flow sampling intervals using standard meters and loggers It is recommended that reported leakage is based on a rolling 7 day 20 percentile using the minimum rolling hour each night. The method will give a leakage estimate for each day. Monthly and annual estimates should be based on the average of available data for the relevant period.
