Overview
Smalandsstenar ARV is a municipal wastewater treatment plant serving Smålandsstenar, Sweden. It treats wastewater for approximately 6,632 people under Sweden's implementation of the EU Urban Waste Water Treatment Directive.
Smalandsstenar ARV is a municipal wastewater treatment plant located in Smålandsstenar, Gislaveds kommun, Jönköpings län, Sweden. The plant serves a population of approximately 6,632 people, classifying it as a small to medium agglomeration under EU criteria. As a Swedish plant, Smalandsstenar ARV operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater and estuaries from agglomerations of this size. Sweden's national regulations enforce strict nutrient removal standards, particularly for phosphorus, to protect sensitive water bodies. The plant's treated effluent is discharged into the Nissan River, which flows southward through Småland and eventually reaches the Kattegat strait, part of the North Sea. The Nissan River supports diverse aquatic life and is an important habitat for salmon and sea trout, making effective wastewater treatment critical for maintaining water quality and ecological health.
Environmental context
Smalandsstenar ARV discharges into the Nissan River, a watercourse that flows through the Småland region before emptying into the Kattegat, a marginal sea of the North Sea. The river supports a variety of fish species, including Atlantic salmon and sea trout, and its ecological health depends on controlled nutrient and pollutant loads. The surrounding watershed is characterized by forested landscapes and agricultural areas, contributing diffuse runoff that the plant's treatment helps mitigate.
