Use of Pumping Stations and Reservoirs for Water Supply in Rural Areas of Central Yakutia

Abstract

The peculiarity of the design, construction and operation of water supply and sanitation systems in the Far North is directly related to the permafrost-climatic and economic factors. This should take into account factors such as the high cost and shortage of electricity, types and nature of production, natural conditions and conditions of water disposal, capacity and features of the regime of water sources. In the early 1990s, the construction of the main water supply system, which consisted of pumping stations, pipelines, reservoirs and canals, began in rural areas of Central Yakutia in order to provide the population with drinking and technical water. This system consists of three branches of main water pipelines: 1 – Lena-Tuora Kuel-Tatta, 2 – Bedeme-Tungulu and 3 – Lena-Muru. The object of study is the main conduit Lena – the Muru. The article presents the results of the study of the main water pipeline «Lena – Muru» for 2014 – 2016 years, compiled schedules of water supply pumping stations in the reservoir, power consumption of electricity and financial costs for it. In addition, the mode of operation of pumping stations of the main water pipeline for the period 2014 – 2017 is analyzed and the ratio of the volume of water supply, electricity consumption and financial costs are shown.
