Skiftesvik Strusshamn Wastewater Treatment Plant, Strusshamn, Norway

Skiftesvik Strusshamn is a wastewater treatment plant located in Strusshamn on the island of Askøy, part of Vestland county, Norway. The facility serves a small population of 140 residents and operates with secondary treatment, which is the standard for smaller agglomerations under Norwegian regulations aligned with the EU Urban Waste Water Treatment Directive. The plant has a designed capacity of 100 cubic meters per day and currently discharges a volume of 60.72 cubic meters per day. As a coastal facility within 10 km of the sea, it plays a key role in protecting the marine environment of the surrounding fjords and the North Sea. Treated effluent from Skiftesvik Strusshamn enters the local coastal waters near Askøy, which are part of the larger Byfjorden system. These waters eventually flow into the North Sea, supporting diverse marine life and important fisheries. The plant's secondary treatment helps reduce organic load and nutrients, mitigating eutrophication risks in the sensitive coastal ecosystem.

The plant discharges into the coastal waters near Askøy, which are part of the Byfjorden system connecting to the North Sea. This area supports diverse marine habitats, including kelp forests and fish spawning grounds. Nutrient inputs from wastewater can contribute to algal blooms, making secondary treatment essential for maintaining water quality in this ecologically productive region.
