Abstract

U ovom radu analizirano je postojeće stanje vodoopskrbnog sustava Ivanić-Grad s detaljnim osvrtom na stanje vodnih gubitaka, a s osnovnim ciljem smanjenja vodnih gubitaka i optimizacije sustava. Analiza se bazirala na utvrđivanju iznosa vodnih gubitaka i tlakova u postojećem stanju u sustavu kako bi se definirale mjere za poboljšanje učinkovitosti sustava. Predložene mjere uključuju ugradnju novih i zamjenu postojećih ventila za regulaciju tlaka, primjenu frekventne regulacije u crpnim stanicama te dodatno smanjenje izlaznih tlakova na postojećim ventilima za regulaciju tlakova i postojećim crpnim stanicama s ugrađenom frekventnom regulacijom. Sve provedene mjere analizirane su s tehničkog i ekonomskog aspekta, uključujući izradu troškovnika i procjenu povrata investicije kroz uštede u potrošnji vode zbog smanjenja vodnih gubitaka i uštede na sanacijama mreže kao posljedica smanjenog broja kvarova (puknuća) u uvjetima reduciranih tlakova.

Abstract (english)

In this thesis, the current state of the Ivanic-Grad water supply system is analyzed with a detailed focus on water losses, aiming primarily at reducing losses and optimizing the system. The analysis is based on determining the amount of water losses and pressures in the current system to define measures for improving system efficiency. The proposed measures include the installation of new and replacement of existing pressure regulation valves, the application of frequency control in pumping stations, and the additional reduction of outlet pressures on existing pressure regulation valves and pumping stations equipped with frequency control. All implemented measures are analyzed from both technical and economic perspectives, including the preparation of cost estimates and the assessment of the return on the investment through water consumption savings due to reduced water losses and network repair savings as a result of fewer failures (breakages) under reduced pressure conditions.
