Summary:

Due to repeatedly occuring water deficit, one of rational methods to increase exploitable resources at non-individual rural water intakes is to periodically store water in small storage reservoirs. The article presents an assessment of the reliability of water abstraction from the water intake situated in the mountainous stream with non-controlled flow as well as with controlled flow after emergency reservoirs and a small storage reservoir were built. Using data from the water intake in the Białka stream, Wilkowice gmina, the influence of water storing on water management efficiency during deficit period is shown.
