Obrenovac municipality drinking water supply status and prospects after the 2014. flood

Abstract

In 2014, major floods in Serbia caused enormous damage in Obrenovac Municipality. Apart from numerous businesses, the flood affected the water supply system. The water source “Vić Bare” in the village of Zabrežje on the Sava river was inundated and the water distribution network, parts of which were relatively old, sustained further harm. Over the past several decades, insufficient groundwater reserves have been one of the main water supply issues in Obrenovac. Recent investigations identified the reserves and the possibility of ensuring additional amounts of groundwater at the existing source was explored. The largest problem, however, is a high water demand due to inefficient water use and water losses in the distribution network. Given that the said water source relies on bank filtration, the flood was extremely important from a hydrogeological perspective. The paper assesses the data collected during the course of extremely high river stages and water tables and examines source discharge capacities to provide further insight into surface water and groundwater interactions and compare the pre- and post-flood status of a municipal water supply source.
