Follese gamle skole Wastewater Treatment Plant, Hetlevik, Norway

Follese gamle skole was a wastewater treatment plant located in Hetlevik, on the island of Askøy in Vestland county, Norway. The plant provided secondary treatment and is now closed, having served the local population in the Follese area. As a coastal facility, it discharged treated effluent into the nearby marine environment. The plant operated under Norway's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for coastal discharges from agglomerations of this scale. Although the plant is no longer operational, its design reflected the regulatory standards for protecting coastal waters in the region. The receiving environment is the coastal waters of the North Sea, specifically the Byfjorden area near Bergen. This marine ecosystem supports diverse aquatic life, including fish stocks and seabird populations, and the plant's treatment helped maintain water quality in this ecologically sensitive coastal zone.

The plant discharged into the coastal waters of Byfjorden, a fjord system connected to the North Sea. This marine environment supports diverse aquatic life, including fish, crustaceans, and seabirds. The proximity to the coast means that treated effluent directly influences local water quality and marine habitats, making secondary treatment essential for minimizing ecological impact.
