Water is essential to the proper functioning of kindergartens and schools. Nevertheless, water consumption in public facilities is usually high, often exceeding the average household water consumption. Recently, increasing pressure on this valuable and depletable natural resource has been noticed and, therefore, it is interesting to study the water consumption in kindergartens and the possibilities of water saving. The present work examined 6 kindergarten facilities in Kyjov, Czech Republic, where the equipment has been enhanced with the faucet water saving technology. The work analyzed the impact of the equipment on the reduction of water consumption as a raw material and on the financial and economic profitability. The results were estimated based on the variation of two parameters such as average daily water consumption and demand per person. The experiment showed that installing the savers resulted in water savings ranging from 8% to 18.7% for average daily consumption and from 10.02% to 23.2% for per capita demand.
