Strusshamn Wastewater Treatment Plant - Coastal Norway Facility

Strusshamn wastewater treatment plant is a municipal facility located in Strusshamn, on the island of Askøy in Vestland county, Norway. The plant serves a population of approximately 850 residents, classifying it as a small agglomeration under Norwegian and EU regulatory frameworks. The plant provides secondary treatment, which is the standard requirement under the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges to coastal waters. Norway, as an EEA member, implements this directive. The plant has a designed capacity of 300 m³/day and currently treats an average daily flow of 368.63 m³/day, indicating operation above its nominal capacity. The treated effluent is discharged into the coastal waters of the North Sea near Strusshamn. The receiving environment is a fjord system that supports diverse marine life, including fish stocks and seabird populations. The plant's coastal location means its discharge is subject to dilution and dispersion, but nutrient loading remains a consideration for local water quality.

The plant discharges into the coastal waters of the North Sea near Strusshamn, part of the larger Byfjorden fjord system. This area supports diverse marine ecosystems, including kelp forests, fish spawning grounds, and migratory seabird populations. The fjord's circulation patterns influence the dispersion of treated effluent, and nutrient inputs from wastewater can affect local algal growth and oxygen levels.
