Norrfjarden avr is a wastewater treatment plant located in Norrfjärden, within Piteå municipality, Norrbotten County, Sweden. The plant serves a population of 6,158 and operates with advanced treatment processes, ensuring high-quality effluent. Its designed capacity is 2,500 m³/day, with a current discharge volume of 966.69 m³/day. As a Swedish plant, Norrfjarden avr operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. Sweden's implementation through national regulations ensures compliance with stringent nutrient removal standards, particularly for nitrogen and phosphorus, to protect the Baltic Sea. The plant is located within 10 km of the coast, discharging into the Bothnian Bay, a sub-basin of the Baltic Sea. This proximity to a sensitive marine environment underscores the importance of advanced treatment to minimize eutrophication risks. The effluent contributes to the local water cycle, supporting aquatic life in the coastal zone.
Environmental context
Norrfjarden avr discharges into the Bothnian Bay, part of the Baltic Sea, a brackish water body highly sensitive to nutrient pollution. The Baltic Sea suffers from eutrophication due to excess nitrogen and phosphorus, making advanced treatment critical. The plant's location near the coast means its effluent directly impacts coastal ecosystems, including fish spawning grounds and migratory bird habitats.
