Kungsgardens avlrverk - Advanced Wastewater Treatment in Backberg, Sweden

Kungsgardens avlrverk is a wastewater treatment facility located in Backberg, within Sandvikens kommun, Gävleborgs län, Sweden. The plant provides advanced treatment, ensuring high-quality effluent before discharge into the local environment. The plant has a designed capacity of 3,000 cubic meters, reflecting its role in managing municipal wastewater for the area. As a Swedish facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and large agglomerations. Sweden's national regulations further enforce strict nutrient removal standards to protect the Baltic Sea. The treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Dalälven river system. This contributes to the ecological health of the region, supporting aquatic life and reducing nutrient loading in downstream waters.

The plant's discharge enters the local watercourse, part of the Dalälven river basin, which flows into the Baltic Sea. The Baltic Sea is a sensitive brackish environment with eutrophication challenges, making advanced treatment crucial for reducing nitrogen and phosphorus loads. The surrounding area includes forests and agricultural lands, where the plant helps maintain water quality for both human use and biodiversity.
