Magnor renseanlegg - Advanced Wastewater Treatment Plant in Magnor, Norway

Magnor renseanlegg is an advanced wastewater treatment facility located in Magnor, a small town in Eidskog municipality, Innlandet county, Norway. The plant serves a population of approximately 1,433 residents, reflecting its role in a small agglomeration. As part of Norway's wastewater infrastructure, it contributes to the protection of local water resources. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 2,800 m³/day and an average discharge volume of 621.46 m³/day, the plant operates well within its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), which Norway implements through the EEA Agreement, advanced treatment is required for discharges into sensitive areas, and this plant meets that standard. The treated effluent is discharged into a local watercourse, which eventually drains into the Glomma River, Norway's longest river, and then into the Oslofjord. The plant's advanced treatment helps protect the downstream aquatic ecosystem and the fjord's water quality, supporting biodiversity and recreational uses.

The plant discharges into a local stream that flows into the Glomma River, which empties into the Oslofjord. The Oslofjord is a vital marine environment supporting diverse fish populations and serving as a key recreational area. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in the fjord and maintain ecological balance.
