STOCKHOLM, Sweden, Feb. 2, 2010 -- Sweco has been commissioned to modernize 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 modernization. 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 modernization is part of a large-scale investment program aimed at addressing wastewater emissions into the Gulf of Finland.
