ABSTRACT
The paper discusses possible impacts of draught on drinking water supplies in water companies. Supplies of drinking water and discharge/treatment of wastewater are among key services provided by water companies in the Czech Republic. Changes in climate pose a potential threat for a sustainable system of drinking water supplies. The last winter has been exceptionally warm which resulted in insufficient replenishment of ground water reserves. Because of little snow the reserves of ground water are not big enough and water company, water administrators as well as owners of water wells will probably have to manage consequences of the exceptionally warm winter. If the period of draught continues, there is a risk that the groundwater reserves will not be able to restore its level before the summer starts. This proves that the draught might be an issue which occurs not only in summer. Water reserves in the Czech Republic depend on precipitation in a form of snow in mountains and that in a form of rainfall in lowlands. The paper discusses the situation in two territories, the result being that the issue should be managed locally. So far, there are only local problems in water supplies in the Czech Republic. But changes in climate are reality which has becoming evident for the past two decades. First, it is essential to focus on preventive measures which will be preparation for draughts.
