Overview
Knappen renseanlegg is a wastewater treatment plant serving approximately 50,587 people in Bergen, Norway. It operates under Norwegian regulations aligned with the EU Urban Waste Water Treatment Directive.
Knappen renseanlegg is a wastewater treatment plant located in the Fyllingsdalen district of Bergen, Norway. Serving a population of around 50,587, it is a medium-sized facility that plays a key role in managing wastewater from this coastal city. As a Norwegian plant, it operates under national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this scale (10,000-100,000 population equivalent), the directive requires secondary treatment or equivalent, with more stringent requirements if discharging into sensitive areas. The plant's designed capacity is 1.00 (likely in million cubic meters per year or similar unit), indicating its scale. The plant discharges into the coastal waters of the North Sea near Bergen. The receiving environment includes the Byfjorden and surrounding fjords, which are ecologically important for marine life, including fish and seabird populations. The region's steep terrain and high precipitation make effective wastewater treatment crucial for protecting water quality in the fjords.
Environmental context
Knappen renseanlegg discharges into the coastal waters of the North Sea via the Byfjorden near Bergen. This fjord system supports diverse marine ecosystems, including fish spawning grounds and migratory bird habitats. The plant's location in a region with high rainfall and steep topography means that proper treatment is essential to prevent nutrient loading and protect the sensitive coastal environment from eutrophication.
