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

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”

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
