Overview
Lahell avlopsanlegg is a wastewater treatment plant serving Hyggen, Norway. It treats wastewater from a population of 6,339 and has a designed capacity of 1.00 (unit unspecified).
Lahell avlopsanlegg is a wastewater treatment plant located in Hyggen, within the Asker municipality of Akershus, Norway. The plant serves a population of approximately 6,339 people, classifying it as a small to medium agglomeration under Norwegian and EU regulatory frameworks. As a Norwegian facility, the plant operates under national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, secondary treatment is typically required, with tertiary treatment in sensitive areas. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Oslofjord, a significant fjord system in southeastern Norway. The Oslofjord supports diverse marine life and is an important recreational and ecological area. Proper treatment helps protect water quality in this sensitive coastal environment.
Environmental context
The plant's treated effluent enters local watercourses that flow into the Oslofjord, a major fjord on Norway's southeast coast. The Oslofjord is ecologically significant, supporting diverse marine habitats, fish populations, and migratory birds. As a coastal water body, it is sensitive to nutrient pollution, making effective wastewater treatment crucial for maintaining water quality and ecosystem health.
