Water losses reduction by managing operational pressure

Abstract

Managing operational pressure is essential for effective reduction of water losses, so system operation is directed towards its maximum reduction with fulfilling the demand of each customer. With this objective, the variable speed drive for pumps was installed on the drinking water treatment plant of Bečej Water Supply System, with downstream pressure control. The reduction of the night pressure for 50% resulted in significant water savings and, hence financial savings. The further improvement can be achieved with the daily pressure regulation, where control can be taken on the most critical location in the network, taking care of the supplying during the periods of the maximum hour consumption.

Upravljanje radnim pritiskom je ključ efikasnog smanjenja gubitaka, pa se rad vodovodnih sistema često usmerava ka njegovom maksimalnom smanjenju, uz zadovoljenje potreba svih potrošača. U tom cilju, na postrojenju za tretman vode za piće vodovoda Bečej je ugrađen frekventni regulator sa kontrolom rada pumpi prema pritisku na samom postrojenju. Smanjenjem noćnog pritiska na ulazu u sistem za 50% postignuta je značajna ušteda vode, a samim tim i finansijskih sredstava. Dalje poboljšanje se može postići dnevnom regulacijom pritiska vodeći računa o snabdevanju tokom perioda maksimalne potrošnje, primenom složenih kontrola rada pumpi, na osnovu pritiska merenog na kritičnim lokacijama u mreži. .
