Overview
Dals Langed avloppsreningsverk is an advanced wastewater treatment plant serving approximately 2,954 people in Dals Langed, Sweden. It discharges treated effluent into the local watershed within the Gota alv basin.
Dals Langed avloppsreningsverk is a municipal wastewater treatment plant located in Dals Langed, a locality in Bengtsfors municipality, Vastra Gotaland county, Sweden. The plant serves a population of approximately 2,954, classifying it as a small agglomeration under Swedish and EU regulations. Its address is Sågbrovägen, Bräckan, Dals Långed. The plant employs advanced treatment processes, which go 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 3,000 cubic meters per day and a reported discharge volume of 463.72 cubic meters per day, the facility operates well within its capacity. Advanced treatment typically includes nutrient removal, reducing the environmental impact on receiving waters. The treated wastewater is discharged into the local watershed, which ultimately drains into the Gota alv river system and then into the Kattegat, a part of the North Sea. The plant plays a crucial role in protecting the water quality of this region, supporting aquatic life and downstream ecosystems. Its inland location, more than 10 km from the coast, reduces direct marine discharge risks.
Environmental context
The plant discharges into the Gota alv drainage basin, which flows through Vastra Gotaland into the Kattegat, a marine area of the North Sea. The watershed supports diverse aquatic habitats and is important for migratory fish species. Advanced treatment helps minimize nutrient loading, protecting downstream lakes and coastal waters from eutrophication.
