Overview
Sellikdalen avlopsanlegg is a wastewater treatment plant serving Kongsberg, Norway. It treats wastewater from approximately 21,000 residents, operating under Norwegian regulations aligned with the EU Urban Waste Water Treatment Directive.
Sellikdalen avlopsanlegg is a municipal wastewater treatment facility located in Kongsberg, Buskerud, Norway. Serving a population of around 21,000, the plant is part of the region's essential water infrastructure, handling domestic wastewater from the town and its surroundings. 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 size (10,000-100,000 population equivalent), the directive requires secondary treatment as a minimum, with more stringent treatment in sensitive areas. The plant's treatment processes are designed to meet these standards, ensuring effective pollutant removal before discharge. The treated effluent is released into the local watershed, which ultimately drains into the Numedalslågen river and then into the Skagerrak strait. This discharge contributes to the ecological health of downstream water bodies, supporting aquatic life and maintaining water quality in the region.
Environmental context
The plant discharges into the Numedalslågen river system, which flows southward through Buskerud and Vestfold before reaching the Skagerrak strait, a part of the North Sea. The downstream environment supports diverse aquatic ecosystems, including salmon and trout populations in the river. The Skagerrak is an important marine corridor for migratory fish and seabirds, making nutrient and pollutant management critical for ecological balance.
