Helsinki Region Environmental Services Authority (HSY) is a municipal body that produces waste management and water services as well as provides information on the Helsinki Metropolitan Area and environment. Its member cities are Helsinki, Espoo, Kauniainen, and Vantaa.

According to a statement, the order was placed by Are, the main technical building contractor of the project. The main project contractor is YIT. The value of the order is not disclosed. Delivery will take place in 2020-2021 and commissioning in 2021-2022.

Valmet DNA is a reliable automation system for managing wastewater treatment processes, said Heikki Tanner, Sales Manager, Process Industry Sales, Valmet.

HSY’s Viikinmäki bedrock treatment plant has been running with Valmet’s automation system since the 1990s. Its Valmet DNA automation system has been updated, and in the future, it will be possible to control the operations of the new Blominmäki bedrock treatment plant from the Viikinmäki control room, too.

HSY is our long-standing partner in solid measurements. We are confident that our solid measurements and innovative technology will provide reliability to the end customer when optimizing their wastewater treatment process, remarked Juha Kesti, Sales Manager, Solids Measurements, Automation, Valmet.

Valmet’s delivery includes a Valmet DNA automation and information management system, field instruments, Valmet Total Solids Measurements, Valmet Low Solids Measurements, and Valmet Dry Solids Measurements. Additionally, the delivery includes field engineering of the automation application and instrumentation, factory acceptance testing, automation system installation, commissioning and training.

The Blominmäki wastewater treatment plant (WWTP) will replace the current Suomenoja wastewater treatment plant, whose capacity is no longer sufficient to treat the entire area’s wastewater due to population growth and higher expectations for intensified wastewater treatment. After its completion in 2022, the treatment plant will process the wastewater of 400 000 residents from Espoo, Kauniainen, Kirkkonummi, Siuntio, and Western Vantaa.
