ООО «CHELNYVODOKANAL» (subsidiary of„KAMAZ“) – high-technology, modern complex of water supply and treatment plants of the town Naberezhnye Chelny and its industries.

Preparation capacities:

Water extraction – 1 200 thou. m³ water/day

Water treatment – 850 thou. m³ water/day

Regional WWTP – 380 thou. m³ water/day     

The prepared drinking water fed into the supply network is completely corresponding to the requirements of SanPiN 2.1.4.1074-01 that is valid for water from central water supply systems and for hygienic standards №2.1.5.2280-07, incl. the chloroform and aluminium standards. The riskless reagent sodium hypochlorite and UV-disinfection are used for the complex water disinfection. Additionally, in the process auf drinking water treatment the active carbon technology is applied for achieving organic norms auf the requirements of SanPiN.
