The condition of the water is checked by 184 indicators at all stages of its journey to the consumer.
From January to June this year, specialists have conducted more than one million studies of the quality of tap water in the capital. This was announced by the Deputy Mayor of Moscow for Housing and Communal Services and Improvement Peter Biryukov.
“Every day the capital consumes 2.8 million cubic meters of water, more than 13 thousand kilometers of water supply networks have been laid in the city,” the deputy mayor said. “This huge system needs constant monitoring: today the state of tap water is analyzed according to 184 physicochemical, microbiological and hydrobiological indicators at all stages of its journey to the consumer”.
Water quality control begins with reservoirs, where samples are taken at different depths. This is necessary in order to identify differences in its composition and get a complete picture of the state of water bodies.
Then the water is checked using automatic analyzers installed at water treatment plants and in the city distribution network. The devices continuously monitor changes in the composition of water: the turbidity, color, and electrical conductivity of the liquid are assessed. Data from the analyzers are fed into a unified information system, which makes it possible to quickly make decisions on changing the technological modes of water purification.
Operational testing of samples is also carried out in specially equipped mobile express laboratories. Experts perform on-site analysis on water supply networks.
The head of the municipal economy complex emphasized that experts monitor water quality around the clock and make adjustments to the water treatment technology. If necessary, additional cleaning is carried out using activated carbon powder or, more often, sand and carbon filters are washed. Thanks to this, the water becomes transparent, disinfected, unpleasant odors and tastes are eliminated from it.
“Experts monitor physicochemical and microbiological indicators around the clock so that fully purified drinking water that meets all the requirements of hygienic standards gets into the taps of Muscovites,” concluded Pyotr Biryukov.
