Abstract
Analiza gubitaka vode u vodoopskrbnim sustavima prema metodologiji Radne skupine za gubitke vode pri Međunarodnom udruženju za vodu (engl. International Water Association - Water Loss Specialist Group, IWA WLSG) postala je standard u Republici Hrvatskoj. Prvi pokazatelj koji je definiran na način da pruži bolji uvid u učinkovitost upravljanja pojedinim vodoopskrbnim sustavom, odnosno prikaže uspješnost isporučitelja vodnih usluga u rješavanju problema vodnih gubitaka je ILI pokazatelj. Ovim radom nastojalo se dokazati kako standardizirani prikaz ILI pokazatelja ima svoje nedosljednosti, odnosno kako se doslovnom interpretacijom može doći do krivih zaključaka. Radom se predlaže korekcija vrijednosti neizbježnih godišnjih stvarnih gubitaka (eng. Unavoidable Annual Real Losses, NGSG) korištenjem metode optimalnog tlaka (MOT). MOT metoda prvi se put uvodi ovim radom te predstavlja dodatni postupak koji se provodi nakon fizičkih mjerenja na terenu. Postupak se sastoji od izrade detaljnog hidrauličkog modela vodoopskrbnog sustava te kalibracije istog korištenjem mjerenih podataka. Takav model ima svrhu definirati optimalni radni tlak. Na ovaj se način sustav dovodi u optimalno stanje funkcioniranja te se analiza ILI pokazatelja provodi na takvom stanju. MOT metoda pronalazi svoju primjenu u analizi vodoopskrbnih sustava koji nemaju implementiran sustav upravljanja radnim tlakovima, odnosno u kojima radni tlakovi nisu optimalni.
Abstract (english)
Analysis of Real losses on water supply systems using IWA WLSG (International Water Association - Water Loss Specialist Group) methodology became standard analysis in Republic of Croatia. First defined indicator that shows efficiency of water supply systems (WSS) regarding real losses is ILI (Infrastructure Leakage Index). The goal of this research was to prove that standardised presentation of ILI value has its inconsistency and that literal interpretation can lead to wrong conclusions. This paper suggests correction of Unavoidable Annual Real Losses - UARL by using Optimal Pressure Method - OPM. OPM is for the first time introduced in this research and represents additional process carried out after physical measurement and before final ILI calculation. Process consists of designing detailed mathematical model and calibrated using measured data. Calibrated model is basis for optimization of real working pressure. In this way, the system leads to an optimal state of functioning and ILI indicator calculation is performed on that condition. OPM method finds its application in the analysis of water supply systems that have no pressure management system and where the actual operating pressure ranges are not optimal.
