Lokketona Wastewater Treatment Plant, Bergen, Norway

Lokketona is a wastewater treatment plant located in the Mjølkeråen district of Bergen, Norway. It serves a small population of 43 people, reflecting its role as a local facility within the broader Bergen municipal wastewater system. The plant is situated in the Vestland region, a coastal area known for its fjords and maritime climate. The plant provides primary treatment, which involves physical processes such as sedimentation to remove solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Norway, as an EEA member, requires appropriate treatment for discharges into sensitive areas. For a plant of this small scale, primary treatment may be considered adequate depending on the receiving environment and local regulations. Current discharge is only 18.65 units. The treated effluent is discharged into the local coastal waters near Bergen, ultimately reaching the North Sea. The area supports diverse marine life, including fish and seabirds, and is important for local fisheries and tourism. The plant's proximity to the coast (within 10 km) means its discharge can directly affect the marine ecosystem, making treatment quality and regulatory compliance critical.

Lokketona discharges into coastal waters near Bergen, which flow into the North Sea. This region supports diverse marine habitats, including kelp forests and fish spawning grounds. The plant's primary treatment level means that only basic solids removal occurs, and the effluent may contain nutrients and pathogens that could impact local water quality and marine life.
