Bommen avlopsanlegg - Advanced Wastewater Treatment in Ørje, Norway

Bommen avlopsanlegg is an advanced wastewater treatment plant located in Ørje, a town in the Marker municipality of Østfold county, Norway. The plant serves a population of 1,776 people, reflecting its role as a small-scale municipal facility in a rural setting. The plant operates with advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC). With a designed capacity of 2,000 m³/day and an actual discharge volume of 770.22 m³/day, the plant has ample capacity to handle current loads. As a Norwegian facility, it complies with national regulations that align with EU standards, ensuring high environmental protection. The treated effluent is discharged into local water bodies that ultimately drain into the Ørje River and then into the larger Glomma River system, which flows into the Oslofjord. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's waterways.

The plant discharges into the Ørje River, a tributary of the Glomma River, Norway's longest river, which flows into the Oslofjord. The Oslofjord is a vital marine environment supporting diverse fish populations and migratory birds. Advanced treatment at Bommen avlopsanlegg reduces nutrient loading, helping to prevent eutrophication in the fjord and maintain water quality for recreational and ecological uses.
