Overview
ARV VADSTENA is a municipal wastewater treatment plant serving Vadstena, Sweden. It treats wastewater for approximately 11,173 people under EU Urban Waste Water Treatment Directive standards.
ARV VADSTENA is a municipal wastewater treatment plant located in Vadstena, Östergötlands län, Sweden. The facility serves a population of approximately 11,173 people, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated near Lake Vättern, one of Sweden's largest lakes, and plays a key role in protecting this important water body. As a Swedish plant, ARV VADSTENA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the discharge is to sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating its scale. The treated effluent from ARV VADSTENA is discharged into the local watershed, which ultimately drains into Lake Vättern. Lake Vättern is a large, deep lake known for its clear waters and diverse aquatic life. The plant's operation is critical for maintaining water quality in the lake and supporting downstream ecosystems, including the Motala Ström river system that flows from the lake to the Baltic Sea.
Environmental context
ARV VADSTENA discharges treated wastewater into the local watershed that flows into Lake Vättern, Sweden's second largest lake. Lake Vättern is a deep, oligotrophic lake with high water clarity, supporting a unique ecosystem including the endemic Vättern char. The lake drains via the Motala Ström river into the Baltic Sea. The plant's location near the lake requires careful nutrient management to prevent eutrophication and protect sensitive aquatic habitats.
