Overview
Ulricehamns avloppsreningsverk serves approximately 9,630 people in Ulricehamn, Sweden. The plant operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive, ensuring treatment standards for inland water protection.
Ulricehamns avloppsreningsverk is a municipal wastewater treatment plant located in Ulricehamn, Västra Götaland County, Sweden. Serving a population of around 9,630, the plant is part of the city's essential infrastructure for managing domestic wastewater from the urban area and surrounding communities. As a Swedish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), transposed into national law. For agglomerations of this size (between 2,000 and 10,000 population equivalent), the directive requires secondary treatment as a minimum. The plant's treatment processes are designed to meet these standards, ensuring effective removal of organic matter and nutrients before discharge. The treated effluent is discharged into a local watercourse that flows into the Ätran River system, eventually reaching the Kattegat strait and the North Sea. The plant plays a key role in protecting the water quality of the Ätran basin, which supports diverse aquatic life and is used for recreation and fishing. By maintaining high treatment standards, the facility helps preserve the ecological health of the downstream environment.
Environmental context
The plant discharges into a local stream that feeds into the Ätran River, which flows westward through southwestern Sweden and empties into the Kattegat, a sea area connected to the North Sea. The Ätran basin supports a variety of fish species, including salmon and sea trout, and is an important migratory corridor. The plant's treatment performance is critical to maintaining water quality in this ecologically sensitive river system, particularly for nutrient-sensitive downstream waters.
