Hamburgsunds avloppsreningsverk - Advanced Wastewater Treatment in Hamburgsund, Sweden

Hamburgsunds avloppsreningsverk is a municipal wastewater treatment facility located in Hamburgsund, a coastal locality in Tanums kommun, Västra Götalands län, Sweden. The plant serves a population of approximately 2,267 residents and is situated near the Skagerrak, an arm of the North Sea. As a small-scale facility, it plays a key role in protecting the local marine environment from untreated sewage. The plant employs advanced treatment processes, which go beyond the secondary treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to reduce eutrophication risks in sensitive coastal waters. The plant has a designed capacity of 4,500 cubic meters per day, with an average discharge volume of 355.88 cubic meters per day, indicating ample reserve capacity for future growth. Treated effluent from the plant is discharged into the coastal waters of the Skagerrak, which connects to the North Sea and ultimately the Atlantic Ocean. This coastal region supports diverse marine life, including fish stocks and seabird populations, and is ecologically sensitive to nutrient loading. The plant's advanced treatment helps mitigate impacts on this important marine ecosystem.

The plant discharges into the Skagerrak, a marginal sea of the North Sea, which is part of the Atlantic Ocean. The Skagerrak is a nutrient-sensitive marine environment that supports diverse ecosystems, including commercial fish species and migratory seabirds. Advanced treatment at this plant reduces nitrogen and phosphorus loads, helping to prevent eutrophication and algal blooms that can harm marine life and local fisheries.
