In this work, the conceptual design of the separated drainage system for the settlement of Škurinje was elaborated. Conceptual design contains the procedure of wastewater drainage towards the wastewater treatment plant Delta. For the positioning of the sewerage system, GEOPORTAL satellite images and maps were used, given by the State Geodetic Administration. In the introduction part of the thesis, basic information are given about the current situation of wastewater drainage system. Parts of sewerage systems and how they work were also explained in this part of the thesis. In the main part of the work, conceptual design for the settlement of Škurinje is described in detail. The existing state of the sewerage system is described in a more elaborate way, and future plans for improvement of the water-communal infrastructure are also given. Hydraulic calculation and sewage system sizing is also made. Also static calculation, pumping station calculation, graphical plans and approximate cost for the all necessary works on building this separated sewerage system are given. In the final part of the thesis, conclusion is made, and the literature used for making this work is listed.
