Overview
BALLEN HAVLEDNING is an advanced wastewater treatment plant in Ballen, Samsø, Denmark, serving about 1,900 people. It discharges treated water near the coast of the Kattegat sea.
BALLEN HAVLEDNING is a wastewater treatment plant located at Ballen Færgehavn on the island of Samsø in the Central Denmark Region. It serves a population of approximately 1,900 residents and operates with advanced treatment technology, reflecting Denmark's high environmental standards for coastal discharges. The plant's advanced treatment level goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. With a designed capacity of 8,624 m³ and an annual discharge volume of about 560 m³, the facility is well-equipped to handle local wastewater loads while protecting the sensitive marine environment. The treated effluent is discharged into the coastal waters of the Kattegat, a shallow sea area connecting the North Sea and the Baltic Sea. This region supports diverse marine life, including fish spawning grounds and migratory bird habitats, making effective nutrient removal critical to prevent eutrophication and maintain water quality.
Environmental context
The plant discharges into the Kattegat, a transitional sea between the North Sea and the Baltic Sea. This area is ecologically sensitive, supporting diverse marine species and serving as an important corridor for migratory birds. Advanced treatment helps reduce nutrient loads that could otherwise contribute to algal blooms and oxygen depletion in the semi-enclosed Baltic Sea basin.
