LOGSTOR is a municipal wastewater treatment plant located in Løgstør, a town in Vesthimmerlands Kommune, Region Nordjylland, Denmark. The plant serves a population equivalent of 18,712, placing it in the medium agglomeration category under EU regulations. As a Danish facility, LOGSTOR 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 million cubic meters per year, and it treats wastewater from the local community before discharging into the Limfjord. The Limfjord is a shallow sound that connects the North Sea to the Kattegat, supporting diverse aquatic life including fish, birds, and marine vegetation. The plant's discharge contributes to the nutrient load in the fjord, which is subject to Danish and EU regulations aimed at reducing eutrophication and protecting the water quality of this ecologically sensitive area.

Environmental context

Treated effluent from LOGSTOR enters the Limfjord, a shallow sound that connects the North Sea to the Kattegat. The Limfjord is an important ecological corridor for migratory fish and birds, and its waters support a variety of marine species. Nutrient inputs from wastewater can contribute to algal blooms and oxygen depletion, making treatment standards critical for maintaining the health of this coastal ecosystem.
