Overview
Jevnaker renseanlegg is a municipal wastewater treatment plant serving approximately 7,500 people in Jevnaker, Norway. The facility operates under Norway's implementation of the EU Urban Waste Water Treatment Directive.
Jevnaker renseanlegg is a municipal wastewater treatment plant located in Jevnaker, Akershus, Norway. The plant serves a population of approximately 7,500, classifying it as a small to medium agglomeration under Norwegian regulations. As a Norwegian facility, the plant operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment or equivalent, with more stringent requirements if the discharge enters a sensitive area. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a scale appropriate for its service population. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Drammensfjord, a fjord branching off the Oslofjord. This coastal discharge area is ecologically sensitive, supporting diverse marine life and serving as a habitat for fish and migratory birds. Proper treatment is essential to protect water quality in the fjord ecosystem.
Environmental context
The treated effluent from Jevnaker renseanlegg flows into the local river system, which drains into the Drammensfjord and then into the Oslofjord, a major fjord on Norway's southeast coast. The Oslofjord is an ecologically important area that supports diverse marine life, including fish populations and seabird colonies. Nutrient loading from wastewater can contribute to eutrophication in the fjord's inner reaches, making effective treatment critical for maintaining water quality and ecosystem health.
