Nossebro avloppsreningsverk - Advanced Wastewater Treatment Plant in Nossebro, Sweden

Nossebro avloppsreningsverk is a municipal wastewater treatment plant located in Nossebro, Essunga Municipality, Västra Götaland County, Sweden. The plant serves a population of approximately 2,300 residents, reflecting its role as a small-scale facility for the local community. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,000 m³/day and an average discharge volume of 360.74 m³/day, the plant operates well within its capacity, ensuring effective treatment of wastewater. The treated effluent is discharged into local watercourses that ultimately drain into the Göta älv river system and then into the Kattegat, a part of the North Sea. This discharge supports the ecological health of downstream waters, including habitats for aquatic life and migratory fish species.

The plant discharges into local streams that flow into the Göta älv river system, which empties into the Kattegat sea area. This watershed supports diverse aquatic ecosystems, including salmonid spawning grounds and important bird habitats. The advanced treatment helps protect these downstream environments from nutrient pollution and other contaminants.
