The decision-making process and selection of technologically suitable and economically viable solutions for the method of waste water collection and treatment in the Šaleška valley

V magistrski nalogi obravnavamo aglomeracije, na katerih so občine, na podlagi zahtev operativnega programa, dolžne v prepisanih rokih zagotoviti odvajanje odpadnih komunalnih voda v kanalizacijo in zagotoviti ustrezno čiščenje na čistilni napravi. Na podlagi analiz MČN do 2000 PE, ki so primerne za manjša naselja, smo izbrali optimalno rešitev za odvajanje in čiščenje odpadnih komunalnih voda iz določenih naselij. Podlage o odločitvi so podane tako iz okoljskega kot tehničnega in ekonomskega vidika. Kriterija, ki sta pomembna pri določitvi izvedljivosti projekta, sta finančni in ekonomski analizi. Pri analizi stroškov smo primerjali investicijske stroške in vzdrževalne ter obratovalne stroške, ki po končani investiciji bremenijo upravljavca komunalne infrastrukture. Za naselje Šentilj smo primerjali investicijske in vzdrževalne ter obratovalne stroške med dvema tipoma MČN, in sicer med SBR sistemom in rastlinsko čisilno napravo.The Master’s Thesis examines agglomerations where the municipalities are bound by the requirements of the Operational Programme to ensure the discharge of utility waste water into the sewerage system within the prescribed deadlines, and to then provide waste water treatment at a suitable plant. Based on the analysis of SWTPs up to 2000 PE, which are suitable for smaller settlements, we selected the optimal solution for the discharge and treatment of utility waste water from selected inhabited localities. The explanations for the decisions are provided both from a technical and an economic standpoint. The two critera, important when deciding on the feasibility of a project, are the financial and economic analyses. When analysing costs, we compared the investment, maintenance, and operating costs, which are borne by the utility infrastructure operator after the conlcuded investment project. When it comes to the town of Šentilj, we compared the investment and maintenance costs between two types of SWTPs: a SBR system and constructed wetlands
