Haglebu avlopsanlegg - Advanced Wastewater Treatment in Eggedal, Norway

Haglebu avlopsanlegg is a wastewater treatment facility located in Eggedal, within the Sigdal municipality of Buskerud, Norway. Serving a population of 429, this plant provides advanced treatment to protect the local environment. The plant is situated in a rural, inland area near Haglebu seter, a mountain farming region. The plant operates with advanced treatment processes, ensuring high-quality effluent. With a designed capacity of 2,900 cubic meters per day and an actual discharge volume of 186.05 cubic meters per day, the facility has ample capacity to handle current loads. As a Norwegian plant, it adheres to national regulations under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The treated wastewater is discharged into the local watershed, which ultimately drains into the Drammenselva river system and then into the Drammensfjord, a part of the Oslofjord. This discharge supports the ecological balance of the region's freshwater and marine environments, contributing to the preservation of aquatic life and water quality.

The plant discharges into the local watershed, which flows into the Drammenselva river and eventually reaches the Drammensfjord, a branch of the Oslofjord. This coastal fjord ecosystem supports diverse marine life, including fish and seabirds, and is an important recreational area. The advanced treatment helps minimize nutrient loading, protecting the fjord from eutrophication.
