Fjallbacka avloppsreningsverk - Advanced Wastewater Treatment in Fjällbacka, Sweden

Fjallbacka avloppsreningsverk is a municipal wastewater treatment plant located in the coastal town of Fjällbacka, in Tanum Municipality, Västra Götaland County, Sweden. The plant serves a population of approximately 1,602 residents, reflecting its role in a small coastal community. Its address on Badhusgatan places it near the harbor area, central to the town's infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into sensitive areas. With a designed capacity of 6,000 cubic meters per day and an average daily discharge of 251.48 cubic meters, the plant operates well below its capacity, indicating room for future growth or seasonal fluctuations. As a Swedish facility, it operates under national regulations that implement EU directives, with oversight from county administrative boards and municipal authorities. The treated effluent is discharged into the surrounding marine environment, as Fjällbacka is situated on the west coast of Sweden along the Skagerrak strait. This coastal discharge supports the local marine ecosystem, which includes diverse fish populations and important habitats. The advanced treatment ensures that nutrient and pollutant loads are minimized, protecting the sensitive coastal waters of the Bohuslän archipelago, a region known for its rich biodiversity and tourism.

The plant discharges into the Skagerrak, a strait connecting the North Sea to the Baltic Sea via the Kattegat. This coastal area is ecologically sensitive, supporting diverse marine life including cod, herring, and seabird colonies. The advanced treatment helps protect water quality in the Bohuslän archipelago, a region with numerous islands and inlets that are important for recreation and fisheries.
