Tanumshede avloppsreningsverk - Advanced Wastewater Treatment in Tanumshede, Sweden

Tanumshede avloppsreningsverk is a municipal wastewater treatment plant located in Tanumshede, Tanums kommun, Västra Götalands län, Sweden. The plant serves a population of approximately 2,853 and has a designed capacity of 4,000 cubic meters per day, with a current discharge volume of 447.87 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. As a Swedish facility, it operates under national regulations that implement EU directives, ensuring high effluent quality standards. The treated wastewater is discharged into the local watershed, which ultimately drains into the Skagerrak, a sea area off the west coast of Sweden. The plant's proximity to the coast (within 10 km) means its discharge can influence coastal water quality and marine ecosystems in the region.

The plant discharges into a watershed that flows into the Skagerrak, a marginal sea of the North Sea. This coastal area supports diverse marine life, including fish populations and benthic habitats. The advanced treatment level helps minimize nutrient and pollutant loads, protecting the sensitive coastal environment from eutrophication and other impacts.
