Skrydstrup Wastewater Treatment Plant, Haderslev Municipality, Denmark

Skrydstrup wastewater treatment plant is located in Haderslev Municipality, Denmark, serving a small community of 793 people. The plant is situated inland, more than 10 km from the coast, and operates under Danish regulations implementing the EU Urban Waste Water Treatment Directive. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. With a designed capacity of 2,500 m³/day and an average discharge volume of 679.25 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that eventually drain into the Baltic Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from nutrient pollution, supporting water quality in the region.

The plant discharges into local streams that flow into the Baltic Sea via the Little Belt. The Baltic Sea is a semi-enclosed brackish sea sensitive to nutrient enrichment, making effective wastewater treatment critical. Skrydstrup's secondary treatment helps reduce organic load and nutrients, contributing to the health of the downstream marine environment.
