Overbygd avlopsrenseanlegg - Secondary Wastewater Treatment Plant in Skjold, Norway

Overbygd avlopsrenseanlegg is a municipal wastewater treatment plant located in Skjold, within the Målselv municipality in Troms, Norway. The plant serves a small population of 480 people, reflecting its role in a rural Arctic community. It is situated near Camp Viking in the Dørumlia area. The plant provides secondary treatment, which is the standard biological treatment stage required under Norwegian regulations for smaller agglomerations. With a designed capacity of 2,600 m³/day and an actual discharge volume of 208.17 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. Norwegian wastewater treatment is governed by the Pollution Control Act and aligns with EU directives through the EEA Agreement. The treated effluent is discharged into the local watershed, which ultimately drains into the Målselva River and then to the Malangen fjord, part of the Norwegian Sea. This Arctic coastal environment supports diverse marine life, including salmon and other cold-water species. The plant's inland location, over 10 km from the coast, reduces direct marine impact, but its discharge still influences downstream water quality.

The plant discharges into the Målselva River basin, which flows into the Malangen fjord and then the Norwegian Sea. This Arctic watershed supports sensitive cold-water ecosystems, including Atlantic salmon and sea trout populations. The fjord environment is ecologically important for migratory fish and marine biodiversity, requiring careful management of nutrient and pollutant loads from upstream sources.
