Pressure management in water supply networks. Technological means
- Resumen
- PressureManagement isthefoundation foreffectiveleakagemanagement. <br/> In many countries it has been widely recognized for at least 30 years that pressure has a fundamental influence on average leakage rates in distribution systems and therefore an everincreasing number of countries and Utilities are now recognizing that good pressure management isthefundamentalfoundationofgoodleakageandinfrastructuremanagement. <br/> Theweightofevidencenowavailable,andtheeverimprovingreliability with whichtechnical and economic predictions can be made, are such that progressive Utilities can no longer afford to ignore investigating possibilities of pressure management in their systems. <br/> Pressure management for leakage control, in its widest sense, can be defined as ¿The practice of managing system pressures to the optimum levels of service ensuring sufficient and efficient supply to legitimate uses and consumers, while reducing unnecessary or excess pressures, eliminating transients and faulty level controls all of which cause the distribution systemto leak unnecessarily¿. <br/> In many cases pressure management addresses not only the effect of real losses but also the causemakingitoneofthemost efficienttoolsforsustainablecontrolofrealloss. <br/> Pressure management programs often have positive impacts on apparent loss reduction and revenue recovery, especially in relation to theft and authorized unbilled consumption. Where customers have roof tanks, pressure management often improves effectiveness of ball valve closure, and improves metering accuracy by reducing the duration of extremely low flows (¿ball valve tails¿) which some meters cannot record. <br/> Thepresentation willshowhowsimpleistheideaofimplementingapressurecontrolsystem and, yet, how effective can be this system be for leakage management.
