HELSINGOR Wastewater Treatment Plant, Helsingør, Denmark

HELSINGOR is a wastewater treatment plant located in Helsingør, Denmark, in the Region Hovedstaden. It serves a population of approximately 22,248 people, classifying it as a medium-sized agglomeration under Danish and EU regulations. The plant is situated along the coast of the Øresund strait, which connects the Baltic Sea to the Kattegat. As a Danish facility, HELSINGOR operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are sensitive to eutrophication. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating its scale. The treated effluent from HELSINGOR is discharged into the Øresund, a narrow strait between Denmark and Sweden. The Øresund is a critical marine environment supporting diverse aquatic life and serves as a migratory corridor for fish and birds. Proper treatment helps protect the strait's water quality and the broader Baltic Sea ecosystem.

HELSINGOR discharges treated wastewater into the Øresund strait, which connects the Baltic Sea to the Kattegat and ultimately the North Sea. The Øresund is a sensitive marine environment with significant ecological value, supporting diverse fish populations, seabirds, and marine mammals. The plant's treatment performance is crucial for preventing nutrient overloading and protecting the strait's water quality, which is subject to eutrophication pressures from surrounding urban and agricultural areas.
