• Description:
• "Reconstruction and rehabilitation of the water supply pipe from Trud station to the village of Stroevo and the water supply network of the village of Stroevo, Maritsa municipality, under two separate positions: Separate position 1: Reconstruction and rehabilitation... "Reconstruction and rehabilitation of the water supply from "Trud" station to the village of Stroevo and the water supply network of the village of Stroevo, Maritsa municipality, on two separate positions: Separate position 1: Reconstruction and rehabilitation of the water supply pipe from the "Trud" station to the village of Stroevo and Separate position 2: Reconstruction and rehabilitation of the water supply network of Stroevo village, Maritsa municipality - STAGE 1.

The amortized pipes will be replaced with HDPE ф250, PN 10 pipes. Volume of the assignment - 1193 l.m. Initial data: Dimensional water quantity: Qmax,h = 19.94 l/s, Qpp = 5.00 l/s, Qor = 19.94 + 5.00 = 24.94 l/s. This amount of water is conducted with pipe: HDPE f250, PN 10; v=0.65 m/s; i=0.002 m/m'; Nzag=2.39 m, Htop = 42 m (provided by a pumping station), Nend = Ntop - Nzag = 42 - 2.39 = 39.61 m. At each highest point along the longitudinal profile of the water supply pipe, a DN50 air valve is installed. The purpose of the above is a device when filling the water pipe with water to release the accumulated air at the highest point and prevent the formation of an air cushion and thus unfavorable hydraulic working conditions.
