This loan has a positive effect on the Baltic Sea environment: 100%
The loan is has been provided for the construction of a wastewater treatment plant in Blominmäki, in the city of Espoo in Southern Finland.
The new plant will replace the wastewater facility in Suomenoja, which is reaching the end of its operational life. The Blominmäki plant will be built underground and treat wastewater from 400,000 inhabitants in the Helsinki metropolitan area.
Commissioning of the new facility is scheduled for 2020.
Helsingin Seudun Ympäristöpalvelut (Helsinki Region Environmental Services Authority) is a municipal federation responsible for water services, waste management and regional information in the Helsinki metropolitan area. The owners of HSY are the municipalities of Helsinki (58%), Espoo (22.3%), Vantaa (19.4%) and Kauniainen (0.3%).
The productivity levels of the Blominmäki facility are expected to be at least 20% higher than those of the existing plant in Suomenoja. The larger treatment capacity of the new plant will be able to accommodate an estimated 50 per cent increase in load volumes between 2015 and 2040.
The new facility will include treatment processes for reducing the levels of nutrients pollution in effluent water. The underground nature of the facility will reduce odour and noise impacts on the surrounding environment.
This is a project with a potentially extensive environmental and/or social impact (category A, read more)
This project has been categorised A, and information about NIB’s considerations regarding financing the project was made public on NIB’s website for 30 days in April–May 2015.
During the construction phase, Helsingin Seudun Ympäristöpalvelut will apply measures to lower noise and vibration impacts on surrounding areas. The tertiary water treatment methods employed in the new plant are expected to reduce the discharge of nitrogen loads to the Baltic Sea by more than 300 tonnes per year. The project is assessed not to have any significant impacts on Natura 2000 areas.
