Overview
Herning wastewater treatment plant serves 187,307 people in Region Midtjylland, Denmark. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Herning wastewater treatment plant is a major municipal facility serving the city of Herning in Denmark's Region Midtjylland. With a population equivalent of 187,307, it is classified as a large agglomeration under EU regulations. The plant is located at Ålykkevej 7, Herning, and plays a critical role in managing wastewater for the region's urban and industrial areas. As a Danish facility serving over 150,000 people, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires tertiary treatment for discharges into sensitive areas. Denmark, as an EU member state, implements this directive through national regulations, ensuring that large agglomerations achieve high treatment standards to protect water quality. The designed capacity of 1.00 (likely in cubic meters per second or similar unit) indicates the plant's scale. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the North Sea via the Skjern River system. This downstream environment supports diverse aquatic life and is important for regional biodiversity. The plant's operation helps maintain water quality in the catchment, which is used for recreation and supports agricultural activities in the surrounding area.
Environmental context
The Herning plant discharges into the Skjern River catchment, which flows into the Ringkøbing Fjord and then the North Sea. This watershed supports a variety of fish species and migratory birds, making it ecologically sensitive. The plant's treatment performance is critical to preventing nutrient enrichment in the fjord, which is a coastal lagoon with limited water exchange.
Frequently asked questions
The plant is located at 7, Ålykkevej, Herning, Herning Kommune, Region Midtjylland, Denmark, 7400.
The Herning plant serves a population equivalent of 187,307 people, classifying it as a large agglomeration under EU regulations.
The treated effluent is discharged into the Skjern River catchment, which flows into Ringkøbing Fjord and then the North Sea.
As a large agglomeration (>150,000 PE), the plant is required to meet tertiary treatment standards under the EU UWWTD, especially given the sensitivity of the downstream Ringkøbing Fjord.
Danish plants of this scale typically employ advanced biological treatment with nutrient removal (nitrogen and phosphorus) to comply with EU and national standards for sensitive areas.
