After the exploitation is finished, it is also reasonable to try to return landscape to it's nautral state as much as possible o ruse it for another activities. Explotation of gravel in the municipality of Kidričevo left a gravel pit, which now the investor wants to turn into recreational zone that would offer: skiing on water, camping, volleyball courts , floating pier and walking trails. For recreational zone to be operative it would have to have needed infrastructure. The designed area currently does not have needed infrastructure. In this master thesis focus will be given to different ways of designing water supply and sewer system.
