Overview
Ytre Enebakk renseanlegg serves the municipality of Ytre Enebakk, Norway, with a population equivalent of 4,512. The plant is located inland, approximately 50 km from the coast, and discharges into the local watershed.
Ytre Enebakk renseanlegg is a wastewater treatment plant located in Ytre Enebakk, a village in Enebakk municipality, Akershus county, Norway. The plant serves a population of 4,512, classifying it as a small agglomeration under Norwegian regulations. It operates within Norway's national water management framework, which aligns with the EU Urban Waste Water Treatment Directive (91/271/EEC) through the EEA Agreement. As a small-scale facility, Ytre Enebakk renseanlegg is expected to provide secondary treatment or equivalent, as mandated by Norwegian law for inland plants serving fewer than 10,000 people. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar units), indicating a modest infrastructure suited to the local population. The plant's treated effluent is discharged into the local watercourse, which ultimately drains into the Oslofjord via the Vansjø-Hobøl water system. This watershed supports diverse aquatic life and is an important recreational area for the region. The plant plays a key role in protecting downstream water quality and the ecological health of the fjord.
Environmental context
Ytre Enebakk renseanlegg discharges into the local river system, which flows into the Vansjø-Hobøl watershed and eventually reaches the Oslofjord, a major fjord on Norway's southeast coast. The Oslofjord is a sensitive marine environment that supports diverse fish populations and serves as a critical habitat for migratory birds. The plant's treatment helps prevent nutrient loading and pollution in this ecologically important water body.
