Alternative methods of sewer systems of municipalities
Podhrázský, Martin ; Raček, Jakub (referee) ; Raclavský, Jaroslav (advisor)
The first part of thesis focus on design of alternative sewer collection systems. Shortly is described the influence of using alternative sewers to quality of wastewater, next are described parts of pressure and vacuum sewer systems and possible ways for designing. The second part applies known for designing both pressure and vacuum sewer system in municipality Lubna, Czech Republic, and compare the cost of construction of alternative sewer systems with traditional gravity system. It is possible to reduce cost of sewer collection systems using alternative ways, mainly when in the locality are inappropriate conditions for a traditional gravity system.

Technologies of reuse of wastewater in place of need
Podhrázský, Martin ; Ševčík, Jan (referee) ; Hlavínek, Petr (advisor)
Final thesis is focusing on possibilities hidden in the potential of wastewaters in sewers. The goal of this thesis is to present technologies and experiences with water reclamation and with heat recovery systems using wastewaters as a source of heat energy. The theoretical part is divided in two main topics. The first topic is focused on bringing important knowledge and experiences with designing and operating decentralized sewer mining systems, which are, due to less favourable environmental conditions, largely applicated and developed in countries such as Australia, California, etc. The second topic is focusing on heat recovery from sewage water and possibilities of heating and cooling buildings. A possibility of using heat energy from sewage for heating and cooling a swimming pool building located in Brno, Czech Republic was assessed in the last part of this thesis. As a source of wastewater was considered a sewer main located near the pool building. Payback periods and economical effectivity of investing into wastewater heat recovery system was compared with centralized heat supply system, which is a very common source of heat energy in Czech Republic.
