Water quality

Water quality control in SUE “Vodokanal of St. Petersburg” is carried out at all stages - from water extraction out of a water source to a metering unit at a house entrance. 

Water quality control in SUE “Vodokanal of St. Petersburg” is implemented in accordance with the approved program. 

The Drinking Water Quality Production Control Program in St. Petersburg was developed in accordance with SanPiN 2.1.4.1074-01 “Drinking water. Hygiene requirements to drinking water supplied by centralized systems. Quality control. Hygiene requirements to the safety of hot water systems”  and approved by TU Rospotrebnadzor (Russian Federal Consumer Rights Protection and Human Health Control Service) of St. Petersburg and by the Chairman of the Committee for Energy and Engineering Support. The program includes 174 checkpoints to control water quality for 111 parameters.

Water quality control is performed in accordance with the following groups of parameters:

  • general
  • organoleptic
  • chemical (organic and nonorganic)
  • microbiological
  • parasitological (giardia cysts)
  • virological (presence of the hepatitis A antigen virus, rotavirus antigens)
  • hydro-biological  (phyto- and zooplankton)
  • radiation safety

 

Water quality control levels:

  • online in-process control by means of automated online analyzers and the automated continuous monitoring;
  • laboratory control;
  • control  by an independent organization – the Federal Center of Hygiene and Epidemiology in St. Petersburg
  • control by Rospotrebnadzor

 The monitoring results show that drinking water in St. Petersburg is harmless in terms of its chemical composition and safe in terms of epidemiological and radiation conditions.

 Moreover, the biomonitoring system developed by scientists from St. Petersburg Research Centre for Ecological  Safety  under the  Russian Academy of Sciences  is used along with the instrumentation control at all city water intakes to monitor water condition in the water source – the Neva River.
