Water quality

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

Water quality control in SUE “Vodokanal of St.Petersburg” is carried out at several levels in accordance with the approved programs.

The Working Program of Potable Water Quality Production Control in St.Petersburg was developed in accordance with SanPin 2.1.4.1074-01 “Potable water. Hygiene requirements to potable 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 adopted by the Chairman of the Committee for Energy and Engineering Support. The program covers 174 points where 86 parameters of water quality are checked.

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

  • Composite
  • Organoleptic
  • Chemical (organic and inorganic)
  • 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 process monitoring with using automated online analyzers
  • laboratory control
  • control  by an independent company - the Water Quality Research Center
  • control by Rospotrebnadzor

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

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