Abstract

U radu je provedena analiza postojećeg stanja vodoopskrbnog sustava Dugo Selo s primarnim osvrtom na količinu vodnih gubitaka i zabilježene tlakove na sustavu. Predložene su mjere optimizacije sustava s osnovnim ciljem smanjenja vodnih gubitaka kroz smanjenje tlakova, a koje se uglavnom odnose na ugradnju ili zamjenu ventila za regulaciju tlaka, uvođenje frekventne regulacije na pojedinim crpnim stanicama ili smanjenje izlazne vrijednosti tlaka na postojećim ventilima za regulaciju tlaka. Predložene mjere analizirane su s tehničko-ekonomskog stajališta. Za sve provedene mjere izrađen je troškovnik mjera, te je dana procjena vremena povrata investicije kroz ostvarene uštede.

Abstract (english)

The paper analyses the current state of the Dugo Selo water supply system with a primary focus on the amount of water losses and recorded pressures on the system. System optimization measures have been proposed with the basic goal of reducing water losses through pressure reduction, which mainly relate to the installation or replacement of pressure regulation valves, the introduction of frequency regulation at individual pumping stations or the reduction of the pressure output value of existing pressure regulation valves. The proposed measures were analysed from a technical and economic point of view. A cost list of the measures was created for all the implemented measures, and an estimate of the investment return time through realized savings was given.
