The master’s thesis presents a proposal on drinking water supply management and waste water discharge in the village of Strmec na Predelu. Following a field visit and a more detailed analysis of the settlement, we found that the village does not have a proper drinking water supply and distribution, whereas urban waste water is drained into individual cesspools. However, the Decree on the discharge and treatment of urban waste water (Official Gazette of the Republic of Slovenia No 98/15) states that individual cesspools should be removed and replaced with small waste water treatment plants by 31 December 2023.
Taking into account the existing community infrastructure as well as demographic, hydrological, topographical and natural characteristics of the village, we dimensioned new water and sewage systems and provided some solutions to improve the current situation of drinking water supply. Two variants for the disinfection of collected water using chlorine dioxide and UV treatment were analysed in the presented proposal on drinking water supply management. We also presented three variants of a shared small waste water treatment plant for urban waste water treatment (constructed wetland, SBR biological treatment plant, and MBR treatment plant).The last part of the proposal presents a cost analysis evaluating the investment, the costs of running and maintenance of every individual segment, and economically most advantageous variant. Last but not least, the proposal for the entire investment regarding urban waste water infrastructure in the village of Strmec na Predelu, which encompasses the construction of new water and sewage systems, drinking water production, urban waste water treatment using the chosen small waste water treatment plant and road resurfacing, was also evaluated.
