The project aims at the completion of 4 new water supply lines in Černošice, Habřiny (built-up area, family houses and recreational buildings) and U Vodárny (family houses) aimed at ensuring the availability of drinking water for the inhabitants of the city in areas where the inhabitants do not yet have access to drinking water and where individual water sources do not have sufficient capacity and quality in the long term. The project will expand the basic infrastructure of the city and improve the quality of life.
