Herrljunga avloppsreningsverk - Municipal Wastewater Treatment in Herrljunga, Sweden

Herrljunga avloppsreningsverk is the municipal wastewater treatment plant for the town of Herrljunga in Västra Götalands län, Sweden. The plant serves a population of around 12,965, classifying it as a medium-sized agglomeration under EU regulations. Located at Tegelbruksvägen, the facility is part of the region's essential water infrastructure. As a Swedish plant, Herrljunga avloppsreningsverk 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 thousands of cubic meters per day or similar units), indicating it is sized to handle the local wastewater load. Sweden's regulatory framework ensures compliance with strict effluent standards to protect water quality. The plant discharges treated wastewater into a local watercourse that ultimately drains into the North Sea via the Göta älv river system. This downstream pathway connects to the Kattegat and Skagerrak straits, supporting diverse aquatic life in both freshwater and marine environments. The plant plays a key role in safeguarding the region's water resources and ecological health.

The treated effluent from Herrljunga avloppsreningsverk enters a local stream that flows into the Göta älv river system, which drains into the Kattegat and ultimately the North Sea. This watershed supports a variety of fish species and provides habitat for migratory birds. The plant's discharge contributes to the nutrient load in the downstream environment, making effective treatment essential for maintaining water quality in the sensitive coastal and marine ecosystems of western Sweden.
