• Description:
• The subject of the order is construction work consisting in the extension of the public water supply and sewage system in the village of Borovnice, district of Borovnice near Staré Paky. The connection with the cap is part of the public water supply and is included in the investment costs for the extension water supply. The proposed public water supply will be made by excavating a PEHD 100RC2 SDR11 ø90 x 8.2 mm pipe with a length of 120.8 m. The connection to the existing public water supply from a PEHD ø 90 mm pipe will be made at the site of the dismantled existing underground end hydrant. The existing gate DN 80 mm in front of the current hydrant will be retained as a sectional closure of the extended water supply. The connection of the new pipeline behind the gate valve is made using a special Hawle cast iron flange No. 0400 DN 80/90 mm. Public water supply made of polyethylene the PEHD 100RC2 SDR11 90 x 8.2 mm pipe with a length of 120.8 m will be mainly laid in the southern part of the affected lands, viz. pp. 7,8. The pipeline will be coiled or in rod design connected by electrical couplings. The minimum slope of the polyethylene pipe will be 3 ‰. Flanged joints will be joined with stainless steel screws. A wire for marking CYKY 4 mm2 will be placed on the pipeline, which will be conductively connected to the subsequent metal fittings or hatches. The public water supply is terminated with a cast-iron flange branch DN 80/80 mm, on which it is installed behind underground hydrant H1 DN 80 mm designed with a slide, serving as an air reservoir. In the straight direction, the branch is blinded by a cast-iron flange secured by a concrete block. The pipes of the proposed water supply will be laid at a depth of approximately 1.60 m below the ground level, which will enable the the requirement to lay the proposed sewer deeper than the water supply. The proposed sewage system will be made of 12 DN/ID 250 mm (PVC-U) pipes with a total length of 115.5 m. connections that...
