Construction of sewage treatment plants, sewerage and water supply in the village Volárna
Obec Volárna | Published December 31, 2015
Procured the works involving the construction of sewage treatment plants, sewerage and water supply in the village Volárna in the Central Region. Pressure sewage drains will be made of PE 100 RC brown color, SDR 11, bar 12 m profile 63x5,8, 90x8,2 and 110x10 with a total length of 4285.0 m. The route of the pressure sewerage will be held in unpaved and paved surfaces (roads) . At the lowest point, the highest point at the end of the pipe is fitted with flushing kit DN 80 serving for pressure sewer cleaning. Furthermore, the highest point of the site is on mains drainage network placed pressure shaft and automatic air vent valve (x2). The design of these valves is justified in terms of hydraulic and subsequently in terms of traffic. Pipe joints will be made electrofittings. Horizontal and vertical fractures pipe fittings are made using PE 100. Horizontal and vertical fractures pipes are secured against displacement by concrete blocks according to TNV 755,410th minimum coverage pressure pipe in communication will average 1.8 m. Waste water from the municipalities will be the wastewater treatment plant fed oddílnou pressure sewers, treated wastewater will be discharged from the COV gravity pipeline to the treated water troughs, which results in approximately 1000 m distant watercourse Bačovka. The purpose of the construction is the disposal of waste water at the newly designed mechanical-biological waste water treatment plant. The proposed technical solution allows prospective sewerage development areas designated by the master plan community for further development. Given the size of the site is designed oddílná sewer network - pressure sewerage, ending mechanical-biological treatment plants. The main water lines "B" will be made of PE 100 RC 110 SDR 17 PN 10, distribution water mains are made of PE 100 RC 90 SDR 17 PN 10, ending hydrant serving as Kalník or air tank.
