Leakage Index Curve and the Longer-Term Effects of Pressure Management
Price: £100
Ref: 03/WM/08/29
ISBN: 1-84057-280-9
This project considers the various methods available of predicting both the short and long term effects of pressure management. The report concludes that there is little practical difference between the methods for the majority of conditions but some have advantages at the extremes and that there is a large variability in pressure-leakage relationships for individual zones. The main recommendation is that a linear pressure-flow relationship can be used in large zones, or where high precision of results is not a priority. There is no evidence of a relationship between pressure and mains repair frequency. Keywords: leakage management, pressure management
