SUNDS Wastewater Treatment Plant, Herning, Denmark

SUNDS wastewater treatment plant is located at 21, Linåvej, Herning, in the Region Midtjylland, Denmark. It serves a population of approximately 4,979, classifying it as a small agglomeration under EU regulations. As a Danish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater and estuaries from agglomerations of this size. The treated effluent is discharged into the local water system, which ultimately drains into the North Sea via the Skjern River and Ringkøbing Fjord. This coastal ecosystem supports diverse aquatic life and is an important area for migratory birds and fish species.

The plant discharges into a watercourse that flows through the Skjern River basin, eventually reaching Ringkøbing Fjord and the North Sea. The fjord is a shallow coastal lagoon that supports diverse aquatic life, including fish and bird populations. The area is ecologically sensitive due to its role as a migratory corridor and nursery habitat for marine species.
