Skogliheimen I Wastewater Treatment Plant, Ask, Vestland, Norway

Skogliheimen I is a municipal wastewater treatment plant located in Ask, a locality in Askøy municipality, Vestland county, Norway. The plant serves a small population of 81 residents, reflecting its role in a rural or peri-urban setting. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under Norway's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. With a designed capacity of 100 cubic meters per day and a current discharge volume of 35.13 cubic meters per day, the plant has ample capacity to handle its service area. Norway's stringent environmental regulations ensure that even small plants meet high treatment standards to protect coastal waters. The treated effluent is discharged into the coastal waters of the North Sea near Askøy. This area supports diverse marine life and is part of the larger North Sea ecosystem, which is ecologically sensitive due to its role in fisheries and migratory bird routes. The plant's proximity to the coast (within 10 km) underscores the importance of effective treatment to prevent nutrient enrichment and protect local marine habitats.

Skogliheimen I discharges treated wastewater into coastal waters near Askøy, which flow into the North Sea. The North Sea is a productive marine ecosystem supporting commercial fisheries, seabird colonies, and marine mammals. Nutrient inputs from wastewater must be carefully managed to avoid eutrophication in this sensitive coastal environment. The plant's secondary treatment helps reduce organic load and protect water quality in the surrounding fjords and coastal areas.
