Ruggevik avlopsrenseanlegg - Harstad, Norway Wastewater Treatment Plant

Ruggevik avlopsrenseanlegg is a municipal wastewater treatment plant located in Harstad, a town in Troms county, northern Norway. The plant serves a population of approximately 1,720 people, placing it in the small agglomeration category under Norwegian regulations. The plant provides secondary treatment, which is the standard level required for coastal discharges under Norwegian law, aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). The designed capacity is 1,215 m³/day, with an average discharge volume of 745.93 m³/day, indicating operational headroom. Treated effluent is discharged into the coastal waters near Ruggevika, part of the Vågsfjorden system, which ultimately drains into the Norwegian Sea. This coastal environment supports diverse marine life, including fish stocks and seabird populations, making proper treatment essential for ecological health.

The plant discharges into the coastal waters of Ruggevika, a bay within the Vågsfjorden system in northern Norway. Vågsfjorden connects to the Norwegian Sea, a productive marine ecosystem supporting fisheries and seabird colonies. The area is ecologically sensitive due to its role as a habitat for cold-water species and migratory birds. Secondary treatment helps reduce organic load and nutrients, protecting local water quality.
