Overview
Saffle avloppsreningsverk is a municipal wastewater treatment plant serving approximately 12,020 people in Säffle, Sweden. It operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
Saffle avloppsreningsverk is the municipal wastewater treatment plant for the town of Säffle, located in Värmlands län, Sweden. The plant serves a population of around 12,020, classifying it as a medium-sized agglomeration under EU regulations. As a Swedish plant, it 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 or similar unit), and it is situated inland, more than 10 km from the coast but within 50 km. The treated effluent is discharged into the local watershed, which ultimately drains into Lake Vänern, Sweden's largest lake, and then via the Göta älv river to the Kattegat and the North Sea. The plant plays a key role in protecting the water quality of Lake Vänern and downstream ecosystems.
Environmental context
The plant discharges into the Byälven river system, which flows into Lake Vänern, one of Europe's largest lakes and a vital freshwater resource. Lake Vänern supports diverse aquatic life and is an important source of drinking water and recreation. The lake drains via the Göta älv to the Kattegat, a strait connecting to the North Sea. Protecting this watershed from nutrient pollution is critical for maintaining ecological balance and water quality.
