Fagerasen renseanlegg - Wastewater Treatment Plant in Trysil, Innlandet, Norway

Fagerasen renseanlegg is a wastewater treatment facility located in Trysil, within the Innlandet region of Norway. The plant serves a population of around 10,500 people, placing it in the medium agglomeration category under Norwegian regulations. As a Norwegian plant, Fagerasen renseanlegg is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which Norway implements through its national legislation. For agglomerations of this size (10,000-15,000 population equivalent), the directive requires secondary treatment as a minimum, with more stringent treatment in sensitive areas. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Glomma River system, Norway's longest river. The Glomma flows southward into the Oslofjord, a critical marine environment supporting diverse aquatic life and important for regional biodiversity.

The plant discharges into the Trysil River catchment, part of the Glomma River basin, Norway's largest river system. The Glomma flows into the Oslofjord, a fjord ecosystem that supports diverse marine species and serves as a vital habitat for fish and bird populations. The region's cold climate and seasonal variations influence treatment operations and receiving water quality.
