Basmo avlopsrenseanlegg - Secondary Wastewater Treatment in Mo i Rana, Norway

Basmo avlopsrenseanlegg is a wastewater treatment plant located in Mo i Rana, a town in Nordland county, Norway. The plant provides secondary treatment for municipal wastewater, serving the local population as part of the region's sanitation infrastructure. With a designed capacity of 959 cubic meters per day, the plant operates under Norway's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for discharges to freshwater and estuaries, with more stringent requirements for sensitive areas. The plant's coastal location means it must meet additional standards to protect marine environments. The treated effluent from Basmo avlopsrenseanlegg is discharged into the Ranfjorden, a fjord that connects to the Norwegian Sea. The fjord supports diverse marine life, including fish populations and seabird colonies. Proper treatment is essential to prevent nutrient enrichment and maintain water quality in this ecologically sensitive coastal ecosystem.

The plant discharges into Ranfjorden, a fjord in Nordland county that flows into the Norwegian Sea. This coastal environment supports a variety of marine species, including Atlantic cod and herring, as well as seabirds. Nutrient inputs from wastewater must be carefully managed to avoid eutrophication, which can harm the fjord's ecological balance and affect local fisheries.
