Overview
Tokjesundet sor is a secondary treatment plant serving 98 people in Osøyro, Norway. It discharges 42.50 m³/day of treated wastewater near the coast of Vestland county.
Tokjesundet sor is a municipal wastewater treatment plant located in Osøyro, within the Bjørnafjorden municipality of Vestland county, Norway. The facility serves a small population of 98 residents and operates with secondary treatment, which is the standard for smaller agglomerations under Norwegian regulations aligned with the EU Urban Waste Water Treatment Directive. The plant has a designed capacity of 223.00 m³/day and currently discharges 42.50 m³/day of treated wastewater. As a secondary treatment facility, it removes organic matter and suspended solids, meeting the requirements for discharges into coastal waters. Norway's implementation of the EU UWWTD mandates secondary treatment for all inland and coastal discharges, with tertiary treatment required for sensitive areas. The treated effluent is discharged into the coastal waters of the North Sea via the local fjord system. The receiving environment supports diverse marine life, including fish and seabird populations, and is part of a region known for its aquaculture and fishing industries. The plant's location within 10 km of the coast means its discharge contributes to the overall nutrient load in the fjord ecosystem.
Environmental context
The plant discharges into the coastal waters of the North Sea via the Bjørnafjorden fjord system. This area is ecologically sensitive, supporting diverse marine habitats including kelp forests and fish spawning grounds. The fjord's circulation patterns influence nutrient dispersal, and the plant's secondary treatment helps reduce organic pollution impacts on the local marine environment.
