Overview
Tierps Avloppsreningsverk serves the municipality of Tierp, Sweden, with a designed capacity of 1.00 and a population equivalent of 20,419. The plant discharges into local waterways, supporting the region's environmental health.
Tierps Avloppsreningsverk is the municipal wastewater treatment plant for Tierp, a locality in Tierps kommun, Uppsala län, Sweden. The plant serves a population equivalent of 20,419, placing it in the medium agglomeration category under Swedish and EU regulations. 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. The designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating the plant's scale. Swedish plants typically employ mechanical, biological, and chemical treatment steps to meet stringent national standards. The treated effluent is discharged into local water bodies within the Norrström basin, which ultimately drains into the Baltic Sea. The plant plays a crucial role in protecting downstream ecosystems, including the coastal waters of the Baltic, which are sensitive to nutrient pollution. By reducing organic load and nutrients, the plant helps maintain water quality in the region.
Environmental context
Tierps Avloppsreningsverk discharges into local streams that are part of the Norrström drainage basin, which flows into the Baltic Sea near the Swedish coast. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient inputs. The plant's treatment helps mitigate eutrophication risks in this ecologically sensitive marine environment, supporting diverse aquatic life and coastal habitats.
