COOPERATION IN ENVIRONMENT-FRIENDLY TECHNOLOGIES F.V. Karmazinov, Director General SUE “Vodokanal of St. Petersburg” The Baltic: Common Sea, Common Concern Late 1980s: St. Petersburg is one of major polluters of the Baltic Sea Since 1989: Cooperation between Vodokanal St. Petersburg and Finland 2011: St. Petersburg meets the HELCOM Recommendations Growth of wastewater treatment volumes . Before 1978 1978 . 1987 2005 2008 2010 2011 2016 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 Total coliforms, CFU/100 ml The Neva water quality at Main WTP’s water intake – average data Total coliforms Thermotolerant coliforms, CFU/100 ml 500 The Neva water quality at Main WTP’s water intake – average data Main WTP Thermotolerant coliforms - Area of direct discharges connected to the NTC - Northern Tunnel Collector MAC 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 N and P load on water bodies in St. Petersburg Reduction of phosphorus discharge – almost 6 times (WWTPs, untreated wastewater discharge) t/year Vodokanal’s plan Mass of N, t/year Mass of P, t/year 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” 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 Centre The Centre was established in 2011 by SUE “Vodokanal of St. Petersburg” and Lahti Science and Business Park (Finland). 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. Objectives: •Organizing international cooperation; •Sharing experience; •Benchmarking of innovations; •Promotion of innovations; •Organizing events to share information, ideas and production / management technologies. 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 Average specific water consumption in St. Petersburg (litres/person/day) 350 305 300 262 250 250 литров/сутки на человека Litres/day per person 250 223 212 195 200 188 168 150 100 50 0 1991 1997 2000 2005 2007 2008 2009 2010 2011 Thank you for your attention!
