Overview
Lokketodalen wastewater treatment plant serves 381 people in Bergen, Norway. It provides secondary treatment and discharges 165.23 m³/day, operating under Norway's implementation of the EU Urban Waste Water Treatment Directive.
Lokketodalen is a wastewater treatment plant located in the Mjølkeråen area of Bergen, Vestland, Norway. It serves a small population of 381 residents, reflecting its role in a suburban or peri-urban setting within the greater Bergen municipality. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Norway, as an EEA member, implements this directive. The plant has a designed capacity of 700 m³/day and currently discharges 165.23 m³/day, indicating it operates well below its capacity. The treated effluent is discharged into the local water system, which ultimately drains into the North Sea via the coastal waters near Bergen. The plant's proximity to the coast (within 10 km) means its discharge can affect the marine environment, making effective treatment important for protecting coastal ecosystems and water quality.
Environmental context
The plant discharges into the coastal waters of the North Sea near Bergen, a region known for its fjords and rich marine biodiversity. The receiving waters support fisheries and are part of a sensitive marine ecosystem. Effective secondary treatment helps reduce nutrient loading and organic pollution, protecting the local marine environment from eutrophication and maintaining water quality for recreational and ecological uses.
