2
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
3
Growth of wastewater treatment volumes 197819872005.. 2008201020112016 Before 1978
4
South-West Wastewater Treatment Plant Put into operation in 2005 Capacity – 330,000 m 3 /day The public-private partnership scheme was used. 15 financing sources 85% of wastewater is discharged treated
5
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
6
Improvement of sanitary-epidemiological condition of the Neva and the Neva Bay in the Gulf of Finland - Area of direct discharges connected to the NTC - Northern Tunnel Collector 500 Thermotolerant coliforms MAC Total coliforms The Neva water quality at Main WTP’s water intake – average data Total coliforms, CFU/100 ml Thermotolerant coliforms, CFU/100 ml Main WTP
7
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.
8
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. Petersburg as “a world-class achievement” Reduction of N and P load on water bodies in St. Petersburg (WWTPs, untreated wastewater discharge) t/year Vodokanal’s plan Mass of N, t/year Mass of P, t/year
9
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)
10
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
11
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
12
International Advanced Water Technologies Centre The 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.
13
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
