Analiza kosztów stacji uzdatniania wód powierzchniowych w Polsce
Analysis of the costs of surface water treatment plants in Poland

Summary/Abstract: Analysis of the unit investment and operating costs of surface water treatment plants shows that these costs decrease together with the growth of the station capacity. Higher costs are incurred for the A2 and A3 category water intakes and lower costs are sustained for the A1 category. The unit investment costs of surface water treatment plants are many times higher than for underground water treatment plants. At the same time the unit operating costs are slightly lower than for underground water treatment plants using physico-chemical processes. The cost structure analysis has shown that depreciation and electricity consumption are the dominant cost components of surface water treatment plants. Salaries and material usage follow and the level of repair costs depends on the technical condition of the station.
