APPROVAL OF THE NEED FOR THE RECONSTRUCTION OF ARENI PUMPING STATION

The Areni-Khachik pumping station raises the waters of the Arpa river from the 976 m mark to the pressure basin located at the 2012 m mark of the upper mountain pass of the Khachik village, from which the water was given to the Khachik community with a maximum output of 415 l/s and to the Amaghu village with a maximum of 41 l/s. with output. The pumping station has three stages, the engine rooms of which are located: First stage, on the right bank of the Arpa river at the mark of 975 m, with a geodetic pumping height of 318 m, pumping output of 582 l/s. Second stage: at the 1295 m mark of the site near the Areni-Khachik highway, with a geodetic elevation of 370 m, pumping output of 456 l/s . And the third stage: at the site of 1651 m near the Areni-Khachik highway, with a geodetic elevation of 361 m, pumping output of 456 l /v . All three stages of the pumping station belong to the class of high-pressure pumping stations, with a relatively small discharge output and high pressure, the specific power consumption of which is significantly higher. Analyzing the technical condition of the pumping station, a program is proposed to implement its reconstruction and reduce operating costs.
