Laxa avloppsreningsverk - Advanced Wastewater Treatment in Örebro län, Sweden

Laxa avloppsreningsverk is a municipal wastewater treatment facility located in Laxå kommun, Örebro län, Sweden. The plant serves a population of approximately 4,030, classifying it as a small agglomeration under Swedish and EU regulations. It is situated inland, more than 10 km from the coast, and its treated effluent contributes to the region's water quality management. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,500 m³/day and an average discharge volume of 632.63 m³/day, the facility operates well within its capacity, ensuring effective treatment of wastewater from the local community. The treated water is discharged into nearby watercourses that eventually drain into the Göta älv river system and ultimately the Kattegat sea. This advanced treatment helps protect the local aquatic environment and supports the ecological health of downstream waters, including habitats for fish and other freshwater species.

The plant discharges into local streams that flow into the Göta älv river system, which drains into the Kattegat, a marine area between Sweden and Denmark. The watershed supports diverse aquatic life, including salmon and trout populations. Advanced treatment at this facility reduces nutrient loads, helping to prevent eutrophication in downstream lakes and coastal waters.
