The City of Subotica has requested a loan from the European Bank for Reconstruction and Development to finance the due to special quaternary sediments in some parts of Vojvodina high concentrations of arsenic in groundwater have been found. Measurements have shown concentrations 10 to 30fold above WHO drinking water guidelines (100 to 150μg/l). 700,000 inhabitants are affected, with a minimum total requirement of 50,000 to 70,000 m³ of drinking water per day.
Partly, alternative groundwater resources are explored in the Danube, Tisa and Sava river sediments. First successful investigations have already been undertaken. In those municipalities which are too far away from the river banks the aim is to selectively remove arsenic from existing drinking water sources by technical means in order to prevent high investment costs into new piping.
Due to the Vojvodinian Provincial Secretariat for the Environment’s initiatives in the region, there are already indications for clustering the municipalities and their founding water associations into three regions. VIENNA ENGINEERS’ role in the process is to clarify legal structures, ownership structures and is to define technological targets for each water source in the study region. The objective is to help small and medium municipalities (SMMs) in getting organized to be able to provide infrastructure to their citizens within the framework of a private public partnership (PPP) model.
