Water Supply and Water Disposal

The company operates in the area of water supply and water disposal services for Subscribers located in the Izhorskie Zavody Industrial Zone.

The company effluent facilities are located at: Saint Petersburg, Kolpino, Izhora left riverside. They are separated, deepened and banked industrial effluent facilities manufactured in 1986, which are consisted of the following:

  • detrittors with the diameter of 6.0 m, 8 pcs;
  • detrittor water supply and water disposal trays;
  • radial (primary) sumps with the diameter of 30.0 m, 4 pcs;
  • pump station building for pumping the precipitate.

The design capacity of existing effluent facilities is 43 thous. m3 per day (94 thous. m3 per day in rainy weather).

Water supply system provides the consumers water supply with potable quality water and service quality water. 

 The potable quality water comes from potable water supply network of Vodokanal SPb State Unitary Enterprise. The service water comes from 2 sources:

  • service Neva non-filtered water comes from pumping station of the 1st rise of Vodokanal SPb State Unitary Enterprise;
  • service sewage effluent comes from the central effluent facilities (CEF) of GSR Vodokanal JSC.

The water disposal system provides the water disposal of industrial, foul water and run-off from the consumers and the territory of the industrial site at Kolpino and CEF territory. Run-offs are transmitted to the centralized system of municipal sewage of Vodokanal SPb State Unitary Enterprise, and the part of run-offs is supplied to CEF for the treatment and service water supply from CEF.

At present, the investment program on the technical re-equipment of GSR Vodokanal JSC industrial facilities is under implementation:

  • reconstruction of CEF facilities and process equipment;
  • reconstruction of water supply / water disposal systems with replacing shut-off valves;
  • construction of precipitate dewatering station.

The implementation of all actions within the framework of the investment program on the technical re-equipment of GSR Vodokanal JSC industrial facilities will allow: 

  • to improve the efficiency and reliability of the GSR Vodokanal JSC economic activity;
the withdrawal obsolete hydrotechnical facilities facilitates improving the area ecological situation.

Investment Schedule

  • 2010–2011: the works on the installation of 4 run-off ultraviolet purification units were performed;
  • 2014–2015: the works on the modernization of pump equipment with replacing with asynchronous with computerized numerical control (CNC) were performed, and this led to reducing the electric energy consumption by more than 2 times;
2015–2017: the works on the creation of the hardware-software complex of pump station management system with a possibility to control all pump station from one dispatching center located in GSR Vodokanal JSC administration building.

In 2020–2022, the following is planned to be done:

  • construction of the precipitate dewatering station;
  • reconstruction of CEF facilities and process equipment, including:
    • reconstruction of stormwater run-off purification system, including detrittors (8 pcs) – 2021–2022;
    • reconstruction of radial sumps (4 pcs) – 2021–2023;
    • reconstruction of wet precipitate station (with replacing the pump equipment and shut-off valves) – 2019–2020;
    • reconstruction of the CEF cold service water supply networks (re-laying incoming service water supply pipelines (DN 150 mm – 320 rm, DN 110 mm – 230 rm, including the replacement of the shut-off valves) – 2019–2021.

The investment volume for the technical re-equipment implementation is more than 700 million roubles.
