Overview
Gol avlopsanlegg is a municipal wastewater treatment plant serving approximately 6,338 people in Gol, Buskerud, Norway. It operates under Norwegian regulations aligned with the EU Urban Waste Water Treatment Directive.
Gol avlopsanlegg is a wastewater treatment facility located in Gol, a town in the Buskerud region of Norway. The plant serves a population of around 6,338 residents, classifying it as a small to medium agglomeration under Norwegian and EU standards. Situated inland, the plant plays a key role in managing municipal wastewater for the local community. As a Norwegian facility, Gol avlopsanlegg operates under national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive typically requires secondary treatment to protect receiving waters. The plant's treatment processes are designed to meet these standards, ensuring effective removal of organic matter and nutrients before discharge. The treated effluent from Gol avlopsanlegg is discharged into local watercourses that ultimately drain into the Hallingdalselva river system, which flows into the Drammenselva and then into the Oslofjord. This downstream connection highlights the plant's role in safeguarding both local freshwater ecosystems and the broader marine environment of the Skagerrak.
Environmental context
The plant discharges into the Hallingdalselva river basin, which flows through the Hallingdal valley and joins the Drammenselva before reaching the Oslofjord. This watershed supports diverse aquatic life, including salmon and trout populations, and is an important recreational and ecological corridor. The Oslofjord, as the ultimate receiving water body, is a sensitive marine environment that benefits from nutrient removal to prevent eutrophication.
