GAMLEBY ARV Wastewater Treatment Plant, Gamleby, Sweden

GAMLEBY ARV is an advanced wastewater treatment plant located in Gamleby, a locality in Västerviks kommun, Kalmar län, Sweden. The plant serves a population of approximately 3,800 and is situated near the coast of the Baltic Sea. It operates under Sweden's implementation of the EU Urban Waste Water Treatment Directive, which requires advanced treatment for sensitive coastal areas. The plant has a designed capacity of 5,800 cubic meters per day and treats an average daily volume of about 598 cubic meters, indicating operational headroom. As an advanced treatment facility, it likely employs processes such as biological nutrient removal to reduce nitrogen and phosphorus, which is critical for protecting the Baltic Sea from eutrophication. The treated effluent discharges into the Baltic Sea, a semi-enclosed brackish sea highly sensitive to nutrient pollution. The plant's location within 10 km of the coast places it in a sensitive area under the EU directive, necessitating stringent nutrient removal. Its operation helps safeguard the coastal waters of Kalmar län and supports the ecological health of the Baltic Sea.

GAMLEBY ARV discharges treated wastewater into the Baltic Sea, a semi-enclosed sea with limited water exchange, making it highly vulnerable to nutrient enrichment. The plant's location in the coastal zone of Kalmar län means its effluent directly influences local marine ecosystems, including seagrass beds and fish spawning grounds. Advanced treatment reduces nitrogen and phosphorus loads, helping to mitigate eutrophication and algal blooms that threaten biodiversity in this ecologically sensitive region.
