BENEFIT-COST ANALYSIS OF SMALL DOMESTIC WASTEWATER TREATMENT PLANTS

Abstract

Due to the historical development of individual regions in Slovakia, there are still areas without access to public water networks. The main reason is the challenging and uneconomical construction of public networks in scattered rural settlements. The small wastewater treatment plants have gained popularity in rural areas of the Slovak Republic. The increasing adoption of decentralized wastewater management is a result of the scattered layout of numerous rural settlements, presenting economic challenges, technical complexities, and inefficiencies in the implementation of a centralized wastewater disposal system. The objective of this paper is to establish a concise methodology for conducting a Benefit-Cost Analysis within the context of the Slovak Republic. This methodology will subsequently serve as an auxiliary decision-making tool when proposing wastewater disposal methods in rural settlements. This study will assess the potential wastewater disposal methods in the specific rural area, while clarifying the proper execution of the benefit-cost analysis.
