Estimating demands for water supply under reduced pressure

Abstract

Many water utilities, continue to operate inefficient water distribution systems (WDSs) with a significant amount of water and revenue losses. This paper investigates the potentials of the available pressure management methodologies and its implementation in the district metering area (DMA) case study in Požarevac. Additionally, focus is given to assessment of water savings due to reduction of pressures. The results indicate that the method which assumes that both consumption and leakage are pressure dependent lead to better prediction of the total amount of water savings under reduced pressures.

Mnoga vodovodna preduzeća i dalje neefikasno upravljaju vodovodnim distributivnim sistemima (VDS) sa značajnim gubicima vode i prihoda. Ovaj rad prikazuje jednu od metodologija za proračun efekata implementacije upravljanja pritiskom u zonama VDS (OZB), na primeru Požarevca. Akcenat je na proceni ušteda u potrebama za vodom usled smanjenja pritiska. Rezultati pokazuju da primena metode, koja pretpostavlja da su i gubici vode i potrošnja vode zavisni od pritiska, daje bolja predviđanja ukupnih ušteda usled smanjenja pritiska.
