As a part of upgradeng the Labin – Raša sewerage system, a new sewerage system for Rogočana and Kranjci settlements should be constructed. The planned sewerage system will consist of two mutually connected gravity channels, one pressure pipeline and one pumping station Rogočana. This paper deals with the analysis of the settlements Rogočana and Kranjci coverage, analysis of anticipated number of resident population at the end of project period, water consumption analysis, analysis of capacity and dimensions of the pumping station, hydraulic calculations of the pressure pipeline, and approximate costs for the sewerage system construction. The graphical annexes show the longitudinal profiles of the gravity channels 1 and 2 and the pressure pipeline 1. All sections needed for detailed understanding of the project are shown. The paper, also, comprise detailed blueprints and layouts of the pumping station Rogočana that has been projected in line with the load estimation and applicable pressure height that are prerequisites for selection of the right type of pumps. All calculations needed for dimensions of the pumping station and pressure pipeline estimation are described.
