Vodokanal reflects on the 2014 milestones


Vodokanal St. Petersburg continued to reduce negative impacts on the city water bodies throughout the Gulf of Finland Year. Dozens of untreated wastewater discharges were closed and wastewater treatment plants were modernized.

That is what the Director General of SUE "Vodokanal of St. Petersburg" Felix V. Karmazinov told at today’s press-conference held at the St. Petersburg Regional Information Center “TASS”.

He pointed out that the untreated wastewater discharge from Petrovskiy Stadium was eliminated in December 2014 under the Neva Untreated Wastewater Discharge Closure Program (9 direct discharges equivalent to 1000 m3/day were closed). Four sewage pumping stations and over 2km of pipelines of different diameter, including inverted siphons under the rivers Zhdanovka and Malays Neva, had to be built to divert effluents from Petrovskiy Stadium. Moreover, the works for the elimination of direct discharges should not have (and, indeed, have not) handicapped the Russian Football Championship and Champions League games. “Not a single match was derailed through our fault, all discharges were diverted in due time”, - stated Felix V. Karmazinov.

Moreover, 19 direct discharges on Petrogradskaya Embankment were diverted in 2014. Seventeen of them (3 combined sewerage discharges, 4,019 m3/day in total; and 14 rainwater discharges, 23 m3/day average) were under the economic jurisdiction of Vodokanal, the remaining 2 were industrial discharges. As a result, the Bolshaya Nevka River became cleaner: before, it received nearly 1.5 Mio. m3/year of wastewater while now all this volume is diverted via collectors to Northern Wastewater Treatment Plant. “By now, Petrogradskaya Storona has been released from almost all polluting effluents discharged untreated into the water", - said Felix V. Karmazinov.

The ongoing construction of the collector on Admiralteyskaya Embankment which began in November this year will be completed in early May 2015. The collector is required to close six direct wastewater discharges in the city centre (near the Bronze Horseman) totaling about 1000 m3/day.

Besides, Vodokanal modernized its wastewater treatment plants in 2014: the works were carried out at the plants in Kronstadt, Kolpino, Pushkin and Pontonniy, as well as at Northern and Central WWTPs.

Felix V. Karmazinov emphasized that the quality of treated effluent at all plants meets the HELCOM recommendations.

Today, 98.4 % of wastewater in Petersburg is discharged treated. Vodokanal intends to increase this figure to 100 % (such target is set out in the Master Plan of Water Supply and Wastewater Disposal in St. Petersburg till 2025 with an Outlook to 2030). To meet this target, all the remaining direct discharges have to be closed. Moreover, Vodokanal is planning to disinfect all treated effluent.

Another big event of the Gulf of Finland Year was the opening of the unique pinnipeds research and preservation centre.

Last year, Vodokanal joined the project aimed to save the Baltic pinnipeds: grey seals and Baltic ringed seals (they are entered into the Red Book). In 2014, the rehabilitation season lasted from 14 March to 16 July. Over this period, 29 animals: 23 Baltic grey seals, 5 Baltic ringed seals and 1 Ladoga ringed seal, have been cured and released into the wild.

After the end of the season, the Centre was reconstructed. Now, it is a unique facility unparalleled in Russia. It can admit up to 40 animals at a time. Moreover, everything necessary is provided for research work there.

In autumn 2014, the Baltic Seal Friends Fund was established. It already has a website - www.balticseal.org. An account for donations is opened, so, everyone interested can participate in the saving of marine pinnipeds of our region now.


One of the most important water supply projects in 2014 is the completion of the construction of new water intake facilities and a new 500,000 m3/day pumping station at Main Water Treatment Plant. Reliability of water supply depends on the stable and high-quality operation of the 1st lift pumping station. Today, Main Water Treatment Plant supplies about 400,000 m3/day of drinking water to Tsentralny, Vasileostrovsky and Petrogradsky Districts, as well as to some parts of Admiralteysky, Primorsky, Kalininsky, Krasnogvardeysky and Vyborgsky Districts.

It is the water intake where water starts its route to customers.

The water intake of the Main Water Treatment Plant is located on the bottom of the Neva River near Smolnaya Embankment. The river water flows by gravity through water intake pipelines to the 1st lift pumping station. From the pumping station it is channeled to the plant where it undergoes a full cycle of water treatment and disinfection.      

The new 1st lift pumping station of Main Water Treatment Plant consists of:

- three parallel gravity water tunnels, 230m each and 1.6m in diameter;

- six advanced intake slotted filters installed at the depth of 13.5m in the gravity pipelines (two filters at each water pipeline);

- the 1st lift pumping station (at the depth of 24m, 8 high-capacity pumps are installed under the ground).

The plant is equipped with unique home-produced water intake filters. They were designed by the experts of LLC “Strong-filtr” in St. Petersburg and manufactured at a production site in the Leningrad Region.  

The construction of the 1st lift pumping station is the first phase of a large-scale project for overall reconstruction of Main Water Treatment Plant. In the coming years, a new 500,000 m3/day water treatment facility will be built there. According to the Director General of SUE “Vodokanal of St. Petersburg”, Vodokanal will largely use home-produced equipment (including products of St. Petersburg companies) for further reconstruction of Main Water Treatment Plant.    

In 2014, Vodokanal was involved in the development of water supply management system for the southern districts of the city. It is the area of 195m2 and the population of about 1.3 Mio. people (6,498 residential houses). The daily average water supply to this area is approximately 500,000 m3/day. The length of water pipelines is 1,578km. 

These districts (Krasnoselskiy, Moskovskiy, Nevskiy and Frunzenskiy) are supplied with water by Southern Water Treatment Plant.

The implementation of the water supply management system requires:

- replacement of the pumping equipment with a more efficient one;

- replacement and installation of shutoff, control and safety valves;

- installation of technical flow meters;

- installation of commercial water meters with a remote data transfer function on the consumer side;

- installation of on-line water pressure / quality control devices in the network and on the consumer side.

The above actions will improve the performance of water supply facilities due to:

- optimization of the pumping stations’ operating regimes,

- reduction of excessive pressure,

- higher reliability of the water distribution system,

- measurement of water consumed by all customer categories,

- reduction of pipe breakdown rate,

- reduction of energy consumption.

A pilot project on water supply management system for Uritskaya pumping station service area (population – around 140,000 people) has already been implemented. Due to the project, energy consumption could be reduced by 41%, water losses and network damages - by 39%.

“Today, the share of energy cost in the unit cost of water treated by Vodokanal is 9%.  It is a rather low percentage compared to other enterprises where the energy cost accounts for 25- 30%”, - emphasized Felix V. Karmazinov. 

The Director General of Vodokanal added that today, water consumption in St. Petersburg is 140 liters per person (at the turn of the last century it was 300 liters per person per day).  Through the reduction of water consumption, hundreds of billions of roubles can be saved and used for the reconstruction of water networks and treatment plants.  


The press-conference held in the St. Petersburg Regional Information Center “TASS” was devoted to the results and further development of the energy sector in St. Petersburg. Vice-Governor of St. Petersburg I.N. Albin, Chairman of the Committee for Energy and Engineering Support A.S. Bondarchuk, and Director General of SUE “Fuel and Energy Complex of St. Petersburg” I.G. Fedorov commented on the performance in the expiring year, challenges and future development of the energy sector.
