VIG Wastewater Treatment Plant, Vig, Denmark - Advanced Treatment for Coastal Protection

VIG is a wastewater treatment plant located in Vig, Odsherred Municipality, Region Sjælland, Denmark. It serves a population of approximately 2,378 people, classifying it as a small agglomeration under Danish and EU regulations. The plant is situated near the coast, within 10 km of the shoreline, and operates under Denmark's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for discharges into sensitive areas. It has a designed capacity of 4,000 m³/day and currently discharges an average volume of 927.25 m³/day, indicating significant spare capacity. As a coastal plant, advanced treatment helps protect the marine environment from nutrient pollution. The treated effluent is discharged into the local watershed, which drains into the Kattegat sea area via small coastal streams. The Kattegat is a sensitive marine ecosystem that supports diverse aquatic life, including fish and seabird populations. The plant's advanced treatment plays a key role in reducing nutrient loads that could otherwise contribute to eutrophication in the coastal waters.

The plant discharges into the local watershed that flows into the Kattegat, a sea area between Denmark and Sweden. The Kattegat is a nutrient-sensitive marine environment that supports diverse aquatic life, including commercially important fish species and migratory birds. Advanced treatment at VIG helps minimize nutrient and pollutant loads, protecting the coastal ecosystem from eutrophication and maintaining water quality for recreational and ecological uses.
