Overview
Haslev C wastewater treatment plant serves the town of Haslev in Region Sjælland, Denmark, with a population equivalent of 14,757. The plant has a designed capacity of 1.00 and operates under the EU Urban Waste Water Treatment Directive.
Haslev C is a wastewater treatment plant located in Haslev, a town in Faxe Municipality, Region Sjælland, Denmark. The plant serves a population of approximately 14,757 people, classifying it as a medium agglomeration under EU regulations. It is situated inland, more than 50 km from the coast, and its treated effluent likely discharges into local watercourses that eventually drain into the Baltic Sea. As a Danish plant serving a population between 10,000 and 100,000, Haslev C is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. The directive also mandates more stringent treatment if the receiving waters are sensitive to eutrophication. The plant's design capacity of 1.00 suggests it is sized to handle the incoming load. The plant's discharge ultimately reaches the Baltic Sea via regional rivers and streams. The Baltic Sea is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Effective treatment at Haslev C helps reduce the load of nitrogen and phosphorus, contributing to the health of downstream aquatic ecosystems and supporting Denmark's commitments under the Baltic Sea Action Plan.
Environmental context
Haslev C discharges treated wastewater into local watercourses that flow into the Baltic Sea via the Øresund or the Great Belt. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to eutrophication from nutrient inputs. Reducing nitrogen and phosphorus loads from treatment plants like Haslev C is critical to mitigating algal blooms and maintaining oxygen levels in the sea's deeper basins.
Frequently asked questions
Haslev C is located at Levetoftevej 37B in Haslev, Faxe Municipality, Region Sjælland, Denmark.
Haslev C serves a population equivalent of 14,757 people, classifying it as a medium-sized agglomeration under EU regulations.
Haslev C discharges treated effluent into local watercourses that eventually drain into the Baltic Sea via the Øresund or Great Belt.
As a Danish plant serving over 10,000 people, Haslev C is required to meet secondary treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). If the receiving waters are sensitive, more stringent nutrient removal may be required.
In Denmark, plants of this scale typically employ mechanical and biological treatment, often with nutrient removal to protect the sensitive Baltic Sea. Many also include tertiary treatment for phosphorus and nitrogen reduction.
