Abstract. The large variability in rainwater quality both in time and location as well as the relatively small number of tests make the preliminary assessment of economic exploitation of these waters difficult. Determining the relation between the conditions and location of rainwater collection and rainwater quality would help to indicate the range of options for rainwater use as well as parameters that require improvement. The aim of the presented article is to establish chosen physical, chemical and microbiological parameters of rainwater and, based on the results obtained, to determine the possibilities for a safe use of these waters in households. The research had been carried out for two years. Samples of chosen rainfalls were collected from spring to autumn from the following roofing materials: concrete roof tiles, ceramic roof tiles, zinc coated metal sheets and epoxy coated. The physical, chemical and microbiological quality assessment has been conducted basing on the following parameters: reaction, turbidity, electrical conductivity, concentration of biogenic compounds, concentration of chosen elements, number of Escherichia coli as well as number faecal streptococci. A significant bacterial contamination, a decreased pH and an increased turbidity of rainwaters were identified, depending on the parameters of the roofing washed by rainfalls and the intensity and frequency of precipitation.

“…Water collected from the galvanized steel sheet roof is distinguished by higher zinc content (3164.55 µg Zn/L) than other samples (less than 1000 µg Zn/L). This dependence on roofing material has also been found by other researchers [39,42,[44][45][46][47]. However, this concentration is not harmful to human health.…”

“…In the experimental studies, various roof coverings were used, and galvanized steel proved to be the cover with the greatest disinfection properties. This may have resulted from an increase in the temperature of the roof surface [39]. The relationship between the roughness of the roof material and the number of microorganisms has been confirmed by the majority of rainwater researchers [22,40].…”

“…This may be the result of the higher total rainfall in 2016. Analyses reported in the literature show that heavy metals can be found in virtually all types rainwater, including water in natural [39], strongly urbanized [25,40], and rural areas [25], as well as in both stored rainwater [17] and the so-called first run-off [41,42]. The sources of heavy metals present in rainwater are the surfaces washed by it since they are points of pollutant accumulation due to dry deposition.…”

The Quality of Rainwater Collected from Roofs and the Possibility of Its Economic Use

The large temporal and spatial variability of rainwater quality, as well as the relatively small number of tests, makes the preliminary assessment of its economic exploitation difficult. Determining the relationship between the conditions and location of rainwater collection and rainwater quality would help indicate the range of options for rainwater use, as well as the parameters that require improvement. The aim of the presented article is to establish the physical, chemical, and microbiological parameters of different rainwater sources and, from the results obtained, determine the possibilities for its safe use in households. The research was carried out for two years. Samples of rainfall were collected from spring to fall from the following roofing materials: Concrete roof tiles, ceramic roof tiles, galvanized steel sheet, and epoxy-coated terrace. The physical, chemical, and microbiological quality were assessed on the basis of the pH, turbidity, electrical conductivity, the concentration of biogenic compounds, the concentration of chosen elements, the number of Escherichia coli, and the number of fecal streptococci. Significant bacterial contamination, decreased pH, and increased turbidity were identified in the water, depending on the parameters of the roofing washed by the rainfall and the intensity and frequency of precipitation.
