Kungsbergets Avloppsreningsverk - Advanced Wastewater Treatment in Gävleborgs län, Sweden

Kungsbergets Avloppsreningsverk is a wastewater treatment facility located in the Gävleborgs län region of Sweden, serving a population of 708. The plant is situated in the municipality of Sandviken, within the broader administrative area of Gävleborgs län. As a small-scale facility, it plays a key role in managing local wastewater from the surrounding community. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 4,400 cubic meters per day, the current discharge volume of 111.14 cubic meters per day indicates significant spare capacity. Under Swedish and EU regulations, advanced treatment is typically required for sensitive areas, and this plant meets those standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Dalälven River system. The plant's inland location, more than 50 km from the coast, reduces direct marine impact. The surrounding region features forests and lakes, and the plant helps protect these water bodies from nutrient pollution, supporting aquatic ecosystems and recreational water quality.

The plant discharges into the local catchment that feeds into the Dalälven River, one of Sweden's major rivers, which flows into the Gulf of Bothnia, a part of the Baltic Sea. The Baltic Sea is a brackish water body sensitive to eutrophication from nutrient inputs. The advanced treatment at this plant helps reduce nitrogen and phosphorus loads, mitigating algal blooms and preserving biodiversity in downstream lakes and coastal areas.
