  • 270,7 km of tunnel collectors
  • 176 wastewater pumping stations
  • 16 wastewater treatment plants (including 13 municipal wastewater treatment plants and 2 surface runoff treatment plants. The largest plants are Central Wastewater Treatment Plant, Northern Wastewater Treatment Plant, South-West Wastewater Treatment Plant)
  • 3 wastewater sludge incineration plants
  • 10 permanent snow-melting stations
  • 6 permanent technically equipped snow collection points

  • The new K-6 water treatment block at the Southern Waterworks

  • Crayfish monitor water state in the Neva River

  • Wastewater Sludge Incineration Plant (The Northern WWTP)

  • Construction of the Northern Sewer

  • South-West WWTP

Vodokanal's major achievements in water treatment:

  • all potable water is UV treated before supply to the city to ensure its epidemiological safety;
  • no liquid chlorine is used for water disinfection, it is replaced with hazard-free, non-toxic sodium hypochlorite;
  • hazard-free and non-toxic ammonia sulfate is used for water ammonization instead of ammonia solutions;
  • a bio-monitoring system is used to check the Neva water quality where the crayfish are chief "inspectors";
  • PAC (powdered activated carbon) dosing system is implemented to remove odor and oil.

Vodokanal's major achievements in wastewater treatment:

  • Since 10 October 2013, 98.4% of all wastewater has been treated in St. Petersburg;
  • St. Petersburg has found a solution to the sludge disposal problem: there are three sludge incineration plants in operation in the city;
  • St. Petersburg wastewater treatment plants have implemented the enhanced nutrient (nitrogen and phosphorus) removal process to meet the HELCOM (the Baltic Marine Environment Protection Commission) requirements. It led to the reduction of biological load on the Neva, the Gulf of Finland and the Baltic Sea.
  • Vodokanal has implemented a biomonitoring system to check the quality of treated effluent (the quality is evaluated by Australian red-claw crayfish) and the composition of flue gases emitting from the sludge incineration plant – with using of giant African snails.

Vodokanal pays a great attention to the awareness raising work. The Company has the Information and Training Centre that includes the Universe of Water Museum Complex and the Youth Environmental Centre.

The International Advanced Water Technologies Centre also operates at premises of Vodokanal. 

Another Vodokanal’s social awareness raising project is the Internet web-site da-voda.com that disseminates the ideas of solicitous attitude to water resources.
