Problems of Drinking and Domestic Water Supply in Mountainous Areas of the Chechen Republic

The article presents the results of assessment works on drinking groundwater of alluvial sediments of the river valleys, perspective for water supply of mountainous regional centers of the Chechen Republic (Itum-Kale, Khimoi, Shatoi and Vedeno villages). The problem of providing quality water to more than 65,000 people living in four regions of the Chechen Republic mountainous areas is becoming more and more critical every year. According to the technical (geological) task, water demand for drinking and domestic water supply of the population is 4.0 thousand m3/day. The assessment of groundwater reserves for domestic and drinking purposes directly in the areas of the above-mentioned settlements was not made earlier, except for Itum-Kalinskoye, where in 2012–2013 HIDEK CJSC performed prospecting and assessment of the underground water reserves in the area of the projected riverbed water intake for the needs of the ”All-season ski resort Veduchi”. Based on the results of these works, the Khacharoiakhk field of fresh groundwater was explored in the alluvial deposits of the Khacharoiakhk River valley, which belong to the upper quaternary and modern quaternary system.

This article is devoted to the urgent problem of drinking water supply in the mountainous regions of the Chechen Republic. The results of the assessment and calculation of groundwater reserves are presented. The article gives a brief assessment of the hydrogeological conditions of the study area, especially the complex of alluvial lower-upper Pleistocene sediments of the overdeepened river valleys, represented by boulder-pebble and boulder-rubbly formations with sand and sand-loamy aggregates. For inventory assessment and choice of a methodology of the reserves calculation in the Research Methods section, the hydrogeological conditions for the formation of groundwater are schematized in all the four study areas (Khimoyskiy, Shatoyskiy, Itum-Kalinskiy, Vedenskiy). On the basis of experimental field hydrogeological works, the calculation hydrogeological parameters necessary for the calculation of the groundwater reserves are determined (the main hydrogeological parameters on the estimated areas are given in the article, in the table 1). In the Methods section, the detailed justification of the scheme of placement of project wells is given (further the wells are supposed to be used as a water intake). For all the four areas – Khimoyskiy, Shatoyskiy, Itum-Kalinskiy and Vedenskiy the “strip aquifer” scheme is adopted as the calculation, limited by two parallel impermeable contours (the slopes of river valleys are composed of impermeable water-resistant bedrocks). In the Results section, all schemes, formulas and brief characteristics of each investigated area (the acreage, the necessary water demand, the type of project water intake) are given. For each area, an security assessment of the calculated reserves is given, which is confirmed by the balance method (all the calculations are given in the article). In conclusion of the article in table 03 the data on the reserves of fresh groundwater based on the results of prospecting-evaluation works of 01.06.2015 are given.
