Slembevegen Wastewater Treatment Plant, Bergen, Norway

Slembevegen is a municipal wastewater treatment plant located in the Nordgardsleitet area of Mjølkeråen, Bergen, in Vestland county, Norway. The facility serves a small population of 57 people, reflecting its role in a localized community within the greater Bergen region. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. Norway implements the EU Urban Waste Water Treatment Directive (91/271/EEC) through its national regulations, which require secondary treatment for all inland discharges and more stringent treatment for sensitive areas. For a plant of this small scale, secondary treatment meets the standard requirements. The plant has a designed capacity of 50 cubic meters per day and currently discharges approximately 24.72 cubic meters per day, indicating it operates well within its capacity. The treated effluent is discharged into the local coastal waters of the North Sea near Bergen. The receiving environment is part of the Norwegian coastal ecosystem, which supports diverse marine life including fish, crustaceans, and seabirds. The plant's location within 10 km of the coast means its discharge can influence nearshore water quality, making effective treatment important for protecting the local marine environment.

Slembevegen plant discharges into the coastal waters of the North Sea near Bergen, Vestland. The area is part of the Norwegian continental shelf, a productive marine ecosystem supporting fisheries and biodiversity. The discharge point is within 10 km of the coast, so treated effluent enters nearshore waters that are ecologically sensitive for juvenile fish and benthic communities. Proper secondary treatment helps minimize nutrient loading and organic pollution in this coastal environment.
