Prastbordets reningsverk - Örnsköldsvik Wastewater Treatment Plant, Sweden

Prastbordets reningsverk is a municipal wastewater treatment plant located in Örnsköldsvik, Västernorrlands län, Sweden. It serves a population of approximately 14,377, placing it in the medium agglomeration category under EU classification. The plant is situated near the coast of the Gulf of Bothnia. As a Swedish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Sweden's national regulations enforce stringent standards for nutrient removal, particularly in sensitive coastal areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating its scale relative to the population served. The plant's treated effluent discharges into the local watershed, which drains into the Gulf of Bothnia, a brackish sea arm of the Baltic Sea. This coastal environment is ecologically sensitive, supporting diverse aquatic life and serving as a critical habitat for fish species. The plant plays a key role in protecting the Gulf of Bothnia from nutrient pollution and maintaining water quality in the region.

The plant discharges into the local water system that flows into the Gulf of Bothnia, part of the Baltic Sea. This coastal region is ecologically sensitive, supporting diverse aquatic life including fish spawning grounds and migratory bird habitats. The Baltic Sea is particularly vulnerable to eutrophication from nutrient inputs, making effective wastewater treatment crucial for preserving water quality and ecosystem health.
