Badeelva Wastewater Treatment Plant, Erdal, Norway

Badeelva is a wastewater treatment plant located in Erdal, a settlement on the island of Askøy in Vestland county, Norway. The plant serves a population of approximately 1,908 people, classifying it as a small agglomeration under Norwegian water management frameworks. Its location near the coast places it in a sensitive marine environment where treatment standards are critical for protecting fjord ecosystems. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater and estuarine discharges from agglomerations of this size. Norway, as an EEA member, implements these standards. The plant has a designed capacity of 3,000 cubic meters per day, with an average discharge volume of 827.46 cubic meters per day, indicating operational headroom. Treated effluent from Badeelva discharges into the coastal waters of the North Sea via the local fjord system. The receiving environment includes the Byfjorden and surrounding marine areas, which support diverse aquatic life and are important for local fisheries and recreation. Effective treatment helps maintain water quality in this ecologically sensitive coastal region.

Badeelva plant discharges into the coastal waters of Vestland, ultimately draining into the North Sea. The local fjord system, including Byfjorden, provides habitat for marine species such as cod, herring, and salmon, and supports migratory bird populations. The area is ecologically sensitive due to its role in nutrient cycling and as a spawning ground for fish. Proper wastewater treatment is essential to prevent eutrophication and protect the marine ecosystem.
