Overview
Kalundborg C wastewater treatment plant serves approximately 20,600 people in Kalundborg, Denmark. Located in Region Sjælland, it operates under the EU Urban Waste Water Treatment Directive.
Kalundborg C is a wastewater treatment plant located in Kalundborg, Kalundborg Kommune, Region Sjælland, Denmark. The plant serves a population of about 20,600, placing it in the medium agglomeration category under EU classification. As part of Denmark's comprehensive wastewater infrastructure, it plays a key role in protecting local water quality. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment as a minimum. Denmark implements this directive through national legislation, ensuring that plants like Kalundborg C meet appropriate treatment standards. The plant's designed capacity is 1.00 (likely in million cubic meters per year or similar unit), indicating its scale. The plant discharges treated effluent into the local watershed, which ultimately drains into the Kattegat sea via the Great Belt. This coastal discharge requires careful management to protect marine ecosystems. The surrounding area includes both urban and industrial zones, with Kalundborg being known for its industrial symbiosis network.
Environmental context
Kalundborg C discharges into the local water system that flows through the Great Belt into the Kattegat, a sea area connecting the Baltic Sea to the North Sea. The Kattegat supports diverse marine life, including fish, seabirds, and benthic communities. As a coastal discharge point, the plant must comply with nutrient reduction requirements to prevent eutrophication in the sensitive marine environment. The watershed includes agricultural and urban runoff, making the plant's treatment role critical for maintaining water quality in the region.
