Marikovfjaera Wastewater Treatment Plant, Erdal, Norway

Marikovfjaera is a secondary-level wastewater treatment plant located in Erdal, a village on the island of Askøy in Vestland county, Norway. The plant serves a small population of 115 residents and has a designed capacity of 250 cubic meters per day, with a current discharge volume of 49.87 cubic meters per day. As a secondary treatment facility, Marikovfjaera meets the minimum treatment standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC), which Norway implements as part of the EEA Agreement. For small agglomerations under 2,000 population equivalent, the directive requires appropriate treatment, which secondary treatment fulfills. The plant's capacity utilization is low, indicating it operates well within its design limits. The plant discharges treated wastewater into the coastal waters of the North Sea near Askøy. The surrounding marine environment supports diverse aquatic life, including fish and seabirds. The plant's proximity to the coast (within 10 km) means its discharge directly influences local fjord ecosystems, which are important for both ecological balance and recreational use.
