Flateby renseanlegg - Wastewater Treatment Plant in Flateby, Norway

Flateby renseanlegg is a wastewater treatment plant located in Flateby, a village in Enebakk municipality, Akershus, Norway. The plant serves a population of approximately 3,459 people, classifying it as a small agglomeration under Norwegian and EU regulations. As a Norwegian plant, Flateby renseanlegg operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, typically secondary treatment, to protect receiving waters. The plant's designed capacity is 1.00 (likely in thousand cubic meters per year or similar unit), indicating a modest scale. The plant discharges treated wastewater into local watercourses that drain into the Glomma River basin, Norway's largest river system. The Glomma flows southward into the Oslofjord, a key marine environment supporting diverse aquatic life and important for fisheries and recreation. Proper treatment at Flateby helps protect downstream ecosystems in the Glomma and the Oslofjord.

Flateby renseanlegg discharges into local streams that feed into the Glomma River, Norway's longest river, which flows into the Oslofjord. The Oslofjord is an ecologically sensitive marine environment supporting diverse fish populations, including cod and herring, and serves as a critical habitat for migratory birds. The plant's treatment performance directly affects water quality in this important coastal ecosystem.
