Purpose: The aim of the article is to identify and assess the differentiation of the financial situation of communes without cities with poviat status in terms of changes in the number of their inhabitants in the eastern and western regions of Poland. Design/methodology/approach: Identification and evaluation of the diversification of the financial situation of communes without cities with poviat status in terms of changes in the number of their inhabitants in the eastern and western regions of Poland. The empirical material of the article consists of figures from the Local Data Bank of the Central Statistical Office in Warsaw for the years 1995 and 2018-2020. They apply both to the entire country and to all municipalities without cities with poviat rights, located in six voivodships of eastern and western Poland, i.e., Lubelskie, Podkarpackie and Podlaskie as well as Dolnośląskie, Lubuskie and Zachodniopomorskie. The collected and structured empirical material was developed in a descriptive, tabular, and graphic form, using the method of comparative analysis. Additionally, a score was made of all diagnostic features illustrating the financial situation of the analyzed local government units in the eastern and western regions of Poland against the background of the entire country for 2018-2020. Findings: The analysis of statistical data showed that changes in the number of population (inhabitants) constitute essential demographic conditions for the economy and financial situation of municipalities without poviat status in the analyzed regions of Poland. It also confirmed the research hypothesis, which assumes that communes in western regions of Poland are in a better financial situation compared to eastern regions, especially those with an increase in the number of inhabitants. Originality/value: The originality of the work is based on the author's approach to the analysis of the undertaken research issues and making a point evaluation of the financial situation of the examined local government units. The work is addressed primarily to local government officials responsible for local government public finances and the possibilities and directions of local socioeconomic development, as well as to decision-makers who implement regional development policy in Poland.

The influence of water price and the number of residents on the economic efficiency of water recovery from grey water

Dobrzański M.

tom Vol. 118, iss. 1

art. no. e2021001

This article presents the results of an analysis of the economic viability of using an installation for the treatment of grey water. Economic indicators in the form of simple payback time (SPBT) and net present value (NPV) were used in the analysis. The use of a dual water supply system should theoretically enable the reduction of the costs of both water supply and sewage disposal, ensuring investment profitability. The article presents the impact of the number of residents as well as the impact of water and sewage on the profitability of using example water-recovery systems. It was found that both factors have a huge impact on the result of the economic analysis. For a small number of residents and at a low price of water supply and sewage disposal, it is not profitable to invest in a water-recovery system. This is due to the high price of purification devices.

W artykule przedstawiono wyniki ekonomicznej analizy opłacalności zastosowania instalacji do oczyszczania szarych ścieków. W analizie zastosowano wskaźniki ekonomiczne w postaci prostego czasu zwrotu (SPBT) i wartości bieżącej netto (NPV). Zastosowanie podwójnego systemu zaopatrzenia w wodę powinno teoretycznie pozwolić na obniżenie kosztów tego zaopatrzenia i odprowadzania ścieków, zapewniając opłacalność inwestycji. W artykule przedstawiono wpływ liczby mieszkańców, a także ceny wody i ścieków na opłacalność wykorzystania przykładowych systemów odzyskiwania wody. Stwierdzono, że oba czynniki mają ogromny wpływ na wynik analizy ekonomicznej. Dla niewielkiej liczby mieszkańców i przy niskiej cenie wody i ścieków nie opłaca się inwestować w system odzyskiwania wody. Wynika to z wysokiej ceny urządzeń do oczyszczania.
