ARV HACKLA is an advanced wastewater treatment plant located in Åtvidaberg, Östergötlands län, Sweden. The plant serves a population of approximately 5,021 people, classifying it as a small to medium agglomeration under Swedish and EU regulations. 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). With a designed capacity of 11,500 m³/day and an average discharge volume of 788.20 m³/day, the facility operates well below its capacity, indicating robust infrastructure for current loads. The treated effluent is discharged into local water bodies that eventually drain into the Baltic Sea via the Östergötland coastal region. The plant's advanced treatment helps protect sensitive downstream ecosystems, including the Baltic Sea, which is vulnerable to eutrophication from nutrient pollution.
Environmental context
The plant discharges into local streams that flow into the Baltic Sea, a brackish water body highly sensitive to nutrient enrichment. Advanced treatment at ARV HACKLA reduces nitrogen and phosphorus loads, mitigating eutrophication risks in the coastal waters of Östergötland. The surrounding watershed supports diverse aquatic life and is an important ecological corridor in the region.
