Overview
Hartevatn renseanlegg is a wastewater treatment plant serving Hovden, Norway, with a population equivalent of 9,100. It operates under Norway's implementation of the EU Urban Waste Water Treatment Directive.
Hartevatn renseanlegg is a wastewater treatment plant located in Hovden, within the municipality of Bykle in Agder county, Norway. The plant serves a population equivalent of 9,100, placing it in the medium agglomeration category under Norwegian and EU regulations. As a Norwegian facility, the plant operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater. Norway's stringent environmental standards ensure that treatment processes meet the directive's requirements for organic matter and nutrient removal. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Skagerrak strait via the Otra river system. This water body supports diverse aquatic life and is an important ecological corridor in southern Norway. The plant plays a key role in protecting downstream water quality in this sensitive region.
Environmental context
The plant discharges into the Hartevatn lake system, which is part of the Otra river catchment. The Otra flows southward through Agder county and empties into the Skagerrak strait near Kristiansand. This watershed supports salmonid populations and is ecologically sensitive due to its role as a migratory corridor for Atlantic salmon and sea trout. The plant's treatment performance is critical to maintaining water quality in this important river system.
