Overview
Fagernes Leira renseanlegg is a municipal wastewater treatment plant serving Leira, Norway. It treats wastewater from approximately 6,579 people in the Innlandet region.
Fagernes Leira renseanlegg is a wastewater treatment plant located in Leira, a village in Nord-Aurdal municipality, Innlandet county, Norway. The plant serves a population of approximately 6,579 people, placing it in the small-to-medium agglomeration category under Norwegian regulations. As a Norwegian facility, the plant operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater in areas with population equivalents above 2,000. For agglomerations of this size, the directive mandates at least secondary treatment to reduce organic matter and suspended solids. The plant discharges treated effluent into the local watershed, which ultimately drains into the Begna River and then into the Tyrifjorden lake system, part of the Drammenselva catchment that flows into the Oslofjord. The receiving waters support diverse aquatic life and are important for recreation and fisheries in the region.
Environmental context
The plant's treated effluent enters the local watercourse, which flows into the Begna River, a major tributary of the Tyrifjorden lake system. From there, water travels through the Drammenselva River to the Oslofjord. The watershed supports salmonid populations and is ecologically sensitive to nutrient loading, making effective treatment essential for maintaining water quality.
