Variantní řešení vnitřní kanalizace rodinného domu v Ostravě

Abstract

The bachelor’s thesis deals with the design of an alternative solution for the internal drainage system of a single-family house in Ostrava. The thesis includes the preparation of detailed design documentation for construction execution. The documentation comprises the architectural and structural design as well as the professional section of building services engineering, with a focus on sanitary installations. The proposed building is a new single-family residential house intended for permanent living by a four-member household. Within the building services engineering section, the design addresses the internal wastewater drainage system, followed by the design of the sewage drainage system, including the method of wastewater discharge and disposal. As no public sewer system for wastewater is available in the given locality, an alternative on-site wastewater treatment solution is proposed on the building plot. The thesis examines two variants of secondary wastewater treatment: a constructed wetland system and a soil filtration system. Mechanical pre-treatment is ensured by an anaerobic separator. The treated effluent is subsequently discharged into an infiltration system consisting of infiltration trenches. The theoretical part of the thesis focuses on the issue of wastewater disposal in areas without access to a public sewer network. It describes in detail the principles of operation of constructed wetlands and soil filtration systems, including their structural design, operational conditions, advantages, and disadvantages. The theoretical section also includes a comparative evaluation of both proposed variants in terms of technical solution, operational requirements, and suitability for the given type of building.
