Overview
TP 688 of Raahen kt is a municipal wastewater treatment plant serving Raahe, Finland. It serves a population of 18,800 and operates under Finnish environmental regulations.
TP 688 of Raahen kt is a municipal wastewater treatment plant located in Raahe, Pohjois-Pohjanmaa, Finland. The plant serves a population of 18,800, placing it in the medium agglomeration category under Finnish and EU regulations. As a Finnish plant, TP 688 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day), and it is subject to national permits issued by the Finnish environmental authorities. The plant is situated within 50 km of the coast, indicating its treated effluent likely discharges into the Gulf of Bothnia via local watercourses. This coastal discharge requires compliance with sensitive area standards under the EU directive to protect the Baltic Sea's fragile marine ecosystem.
Environmental context
The plant's treated wastewater ultimately reaches the Gulf of Bothnia, a northern arm of the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient pollution. Discharges from plants like TP 688 contribute to the overall nutrient load, which can lead to eutrophication and algal blooms. Finnish regulations require advanced treatment for plants discharging into sensitive areas to mitigate these impacts.
