摘要：A common economic use of rainwater is the basis for strategies
that will allow the water sector to adapt to progressive climate change.
Rainwater is a basic part of water resources that ensures the renewal of the
surface and groundwater, therefore they should be protected against
pollution and be managed and used in places of rainfall. This is particularly
true for heavily urbanized, agricultural and industrial areas. Stormwater
collection and storage systems have been introduced in many countries [1].
The water obtained in this way is a valuable source of fresh water, thanks
to which it is possible to reduce the demand for tap water by almost 60%
or use it during periods of drought [1, 2]. The idea of the sustainable
management of water resources and the increasing ecological
consciousness of society have allowed installations for the collection and
use of rainwater in residential houses and public buildings to become an
increasingly popular phenomenon [3, 4]. The research and assessment of
rainwater quality is a guarantee of safety for its users. The article presents
the results of research on the physical and chemical quality of rainwater
collected directly from precipitation. Samples for research were collected
in a suburban area during March-November 2015. The pH, turbidity,
permanganate index, OWO, nitrogen compounds, phosphates, oxygen
content, acidity, basicity, conductivity, hardness, and heavy metals content
were determined. The obtained results were the basis for indicating the
possibility of using rainwater for various economic purposes.
