Tejn Renseanlaeg - Wastewater Treatment Plant in Tejn, Denmark

Tejn Renseanlaeg is a municipal wastewater treatment plant located in Tejn, a town on the island of Bornholm in Denmark's Region Hovedstaden. The plant serves a population of approximately 3,451 residents, classifying it as a small agglomeration under EU regulations. As a Danish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar units), indicating it is scaled to handle local wastewater flows. The treated effluent from Tejn Renseanlaeg ultimately discharges into the Baltic Sea, which is a sensitive marine environment. The plant plays a key role in protecting coastal water quality around Bornholm, supporting local ecosystems and recreational uses.

Tejn Renseanlaeg discharges into the Baltic Sea, a brackish inland sea with limited water exchange, making it sensitive to nutrient pollution. The plant's location on Bornholm means its effluent affects local coastal waters and the broader Baltic ecosystem, which supports diverse aquatic life and is an important migratory corridor for fish and birds.
