GADSTRUP Wastewater Treatment Plant, Roskilde, Denmark

GADSTRUP is a wastewater treatment plant located in Roskilde, Denmark, within Region Sjælland. It serves a population of approximately 3,781, classifying it as a small agglomeration under EU regulations. The facility is situated at Svanevej 16, Roskilde Kommune, and plays a role in managing local wastewater. As a Danish plant, GADSTRUP operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day), indicating a modest scale. The plant's treated effluent likely discharges into local watercourses that drain into the Øresund or the Baltic Sea. This region supports diverse aquatic life and is important for migratory birds. Proper treatment helps protect downstream ecosystems and coastal water quality.

The plant is located within 50 km of the coast, with its discharge likely entering the Øresund strait via local streams or rivers. The Øresund connects the North Sea to the Baltic Sea, a brackish environment with sensitive marine habitats. Effective treatment reduces nutrient loading, which is critical to prevent eutrophication in the Baltic Sea, a semi-enclosed sea with limited water exchange.
