COOPERATION IN
ENVIRONMENT-FRIENDLY
TECHNOLOGIES
The Baltic: Common Sea, Common Concern
Late 1980s:St. Petersburg is one of major polluters of the Baltic Sea
2011:St. Petersburg meets the HELCOM Recommendations
Since 1989:Cooperation between Vodokanal St. Petersburg and Finland
Growth of wastewater treatment volumes

South-West Wastewater Treatment Plant
Put into operation in 2005
Capacity – 330,000 m3/day
The public-private partnership scheme was used.15 financing sources
85% of wastewater is discharged treated
Northern Tunnel Collector Extension in Petersburg
Put into operation (stage-by-stage) in 2008 – 2012
Length of main tunnels – two lines, 12.2km each
Diameter – 4m
Depth – 40-90m
Result: 95% of wastewater is discharged treated
Improvement of sanitary-epidemiological condition of the Neva and the Neva Bay in the Gulf of Finland

The Clean Baltic Sea Project
Enhanced phosphorus removal technologies are implemented at all WWTPs in St. Petersburg.
Approximately, 10 tons/day of phosphorus are removed.
The average phosphorus concentration in the total wastewater discharge – 0.5 mg/l
HELCOM Recommendations are fully complied with.
Enhanced nutrient removal
Reduction of phosphorus discharge – almost 6 times
Reduction of nitrogen discharge – almost 2.5 times
Result: fewer blue-green algae in the Gulf of Finland
Tarja Halonen referred to the wastewater treatment Improvements in St. Petersburgas “a world-class achievement”
Reduction of N and P load on water bodies in St. Petersburg

Eutrophication of the Baltic Sea
The photo is made by NASA on the order of the Swedish Institute of Meteorology and Hydrology.
It was demonstrated at WWF Workshop (August 2011, Stockholm)
Sewage sludge disposal
Petersburg is the first big city to fully solve the sludge disposal problem.
Number of sludge incineration plants – 3
Reduction of sludge volume – 10 times
Electricity production in 2011 – 10,500 MW
Biomonitoring
The composition of flue gases at sludge incineration plants is checked by snails
Wastewater treatment quality is monitored by crayfish alongside with instruments
The biomonitoring systems have been designed by the St. Petersburg Scientific Research Centre of Environmental Safety at the Russian Academy of Sciences
International Advanced Water Technologies CentreThe Centre was established in 2011 by SUE “Vodokanal of St. Petersburg” and Lahti Science and Business Park (Finland).
Objectives: •Organizing international cooperation; •Sharing experience; •Benchmarking of innovations; •Promotion of innovations; •Organizing events to share information, ideas and production / management technologies.
The Centre cooperates with the Northern Dimension Business Council (NDBC) Working Group on Environment and Nature Conservation in the North-West Russia and with the Northern Dimension Environmental Partnership.
Environmental education
Youth Environmental Centre: •Active since 2002, •12 projects implemented in 2011 Russian-Finnish programmes are being implemented
The Universe of Water museum complex •Active since 2003, •The number of visitors – over 215,000 in 2011
