The aim of the thesis is to design a sewer system for the village of Nitriansky Hrádok. In this work I deal with the design of sewer system according to sewer system design principles. The goal is also a preliminary proposal for alternatives to the sewage network, due to the complex terrain arrangement and due to hydrogeologically inappropriate conditions. When designing a sewer network, I deal with two alternates, namely the gravity sewer network and the pressure sewer network. Both alternatives are designed using SeWaCAD and AutoCAD drawing documentation.The aim of the submitted thesis is to propose the most suitable route and present an alternative to the sewer network for the municipality of Nitriansky Hrádok.
