City of St. Petersburg is constantly developing its wastewater treatment. Reconstruction of half of the biological treatment unit at Northern wastewater treatment plant is one of the initiatives.
The treatment plant is the biggest plant in St. Petersburg serving the population of approximately 2 million people.
The project will be implemented within three contracts: Design Build Contract to reconstruct the plant and install the equipment and two Supply Contracts to supply the main equipment. Total costs of the project are approximately EUR 40 million. Pöyry has supported the client in various phases during the reconstruction project, ranging from detail design to commissioning and training of operation staff.
