Hallsbergs avloppsreningsverk, Hallsberg

Overview

Hallsbergs avloppsreningsverk serves approximately 10,127 people in Hallsberg, Sweden. The plant operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive.

Hallsbergs avloppsreningsverk is a municipal wastewater treatment plant located in Hallsberg, Örebro län, Sweden. Serving a population of around 10,127, the plant is part of the local infrastructure managed by the municipality. As a medium-sized agglomeration, it plays a key role in protecting water quality in the region. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Sweden requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized appropriately for the population served. Compliance with national regulations ensures effective treatment before discharge. The plant discharges treated wastewater into a local watercourse that ultimately drains into the Baltic Sea via the Norrström basin. This connection to the Baltic Sea, a sensitive marine environment, underscores the importance of proper treatment to reduce nutrient loading and protect aquatic ecosystems.

Environmental context

The treated effluent from Hallsbergs avloppsreningsverk enters a local watercourse that flows into the Norrström drainage basin, eventually reaching the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient pollution. Effective wastewater treatment is critical to minimize eutrophication and support diverse aquatic life in this ecologically important water body.
