Indicators of the quality of drinking water must meet O'zDSt 950:2000, both in
toxicological and microbiological, parasitological and organoleptic characteristics. As is
evident from the results of tests, the water does not always meet these requirements, such as
on the dry residue, hardness, sulfates, as well as microbiological, parasitological indicators.
In coordination with the SES is allowed to use water with higher rates, affecting the
organoleptic properties of water (salinity up to 1.5 g / dm 3, the hardness of up to 7).
The relief of the construction area MCC level, planned. The surface area is free of
developments.
In lithological respect of the area is complicated by a thick Paleogene-Neogene rocky
soils, represented by limestones with intercalations of sandstone, marl, mudstone. These
deposits from a surface covered with thin (few meters) from the Upper clastic and finegrained
formations.
The geological structure of the site involved three geotechnical elements (IGE):
The first engineering-geological elements (IGE-1). Yellowish-brown sandy loam,
dry, macroporous, subsident, salty, with the inclusion of fragments of limestone up to 20%.
Capacity from 0,5 to 1,5 m.
