Conceptual study to drainage water and treatment of waste water for the settlements Žlebič, Slatnik and Sušje

Subject of study are settlement Žlebič, Slatnik and Sušje in the municipality of Ribnica. The above\ud mentioned villages are detailed conceptual design solutions discharges and wastewater treatment.\ud They offer the following variants: VARIANT I: sewerage systems to individual small treatment plants\ud (sewerage system Žlebič, sewerage system Slatnik and sewerage system Sušje), VARIANT II:\ud sewerage system with more common small treatment plants (sewerage system Žlebič-Slatnik,\ud sewerage system Sušje) and VARIANT III: sewer system with a common small sewage treatment\ud plant (sewerage system Žlebič-Slatnik-Sušje). Presented are procedures in design and construction of\ud fecal sewerage system with all supporting facilities. Especially hydraulic calculation shows fecal\ud sewage and described variants of storm water discharges solutions with the state. In the last part of the\ud study construction costs are calculated, operation and maintenance of each system (for every variant\ud there are two typs of small treatment plant presented – biological and wetland), and based on\ud cost analysis of selected rational and economically most suitable variant
