SWECO WINS NEW ENVIRONMENTAL CONTRACT IN RUSSIA

SWECO WINS NEW ENVIRONMENTAL CONTRACT IN RUSSIA

Sweco has been commissioned to modernise St. Petersburg's northern wastewater
treatment plant, a facility that will take care one fifth of the city's water.
Among other things, the project will lead to reduced emissions of phosphorous
and nitrogen in the Baltic Sea. The contract is worth over EUR 730,000.

“Sweco carried out its first international assignment in Russia more than 100
years ago. Both then and now, our goal is to contribute to a better environment
for the people around the Baltic Sea,” says Sweco's CEO Mats Wäppling. 

St. Petersburg's northern wastewater treatment plant will be upgraded to meet
the requirements in the Helsinki Convention on the Protection of the Marine
Environment in the Baltic Sea Area. Treatment of phosphorous and nitrogen will
be improved and substantial energy savings, up to 20 GWh per year, are also
planned in connection with modernisation. Sweco's contract includes both
engineering design and construction control services. 

One million of the city's five million residents are connected to the plant,
which is dimensioned for a load of 1,000,000 m3 per day. 

The assignment will be carried out by Sweco's environmental consultants in
Sweden and Russia. The modernisation is part of a large-scale investment
programme aimed at addressing wastewater emissions into the Gulf of Finland.
