As of today, the water supplied to consumers from the Dniester WTP complies with current sanitary standards and requirements of SanPiN 2.2.4-171-10 for drinking water.
Before being supplied to Odesa, the water undergoes thorough multi-stage purification and disinfection at the Dniester WTP, where timely replacement of fast filters and equipment modernization are carried out.
However, due to the long distance of consumers from the water intake, the water in Odesa is additionally disinfected at all city pumping stations, which "Infoxvodokanal" was one of the first in Ukraine to switch to a new safe water disinfection technology using sodium hypochlorite. For this, the company invested over 5 million hryvnias in German and Austrian equipment and the highest quality reagents.
The water quality is monitored around the clock by highly qualified specialists of the central chemical-bacteriological laboratory of the "Infoxvodokanal" branch, according to more than 55 indicators in the modernized laboratory on equipment from leading global manufacturers. Additionally, the water quality is checked by the "Odesa Laboratory Center of the Ministry of Health of Ukraine." The work of "Infoxvodokanal" on water purification has been inspected by European experts of the international TACIS program and recognized as absolutely reliable.
