STENSELE AVLOPPSRENINGSVERK - Advanced Wastewater Treatment in Stensele, Sweden

STENSELE AVLOPPSRENINGSVERK is an advanced wastewater treatment facility located in Stensele, Västerbottens län, Sweden. The plant serves a population of 1,529 and is designed to handle up to 4,000 cubic meters of wastewater per day, with a current discharge volume of 240.02 cubic meters daily. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment ensures high-quality effluent, reducing nutrients and pollutants before discharge. The treated effluent is released into the local watershed, which ultimately drains into the Ume River and then the Gulf of Bothnia. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the Ume River and the Baltic Sea, supporting biodiversity and water quality in the region.

The plant discharges into the Ume River catchment, which flows into the Gulf of Bothnia, part of the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Advanced treatment at this plant helps reduce eutrophication risks and supports the ecological health of downstream waters, including important fish spawning and migratory bird habitats.
