Storvreta Avloppsreningsverk - Advanced Wastewater Treatment in Storvreta, Sweden

Storvreta Avloppsreningsverk is an advanced wastewater treatment facility located in Storvreta, Uppsala County, Sweden. The plant serves a population of around 3,545 residents, reflecting its role as a medium-sized municipal treatment facility in the region. The plant employs advanced treatment processes, ensuring high-quality effluent standards. With a designed capacity of 8,000 m³/day and a current discharge volume of 556.5 m³/day, the facility operates well within its capacity. As a Swedish plant, it complies with national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and agglomerations of this scale. The treated effluent is discharged into local waterways that ultimately drain into the Baltic Sea. The plant's inland location, more than 10 km from the coast, reduces direct marine impact. Its advanced treatment level helps protect downstream aquatic ecosystems and supports the ecological health of the region's water bodies.

The plant discharges into the local river system within the Fyrisån basin, which flows through Uppsala and into Lake Mälaren, eventually reaching the Baltic Sea. The Baltic Sea is a brackish water body sensitive to nutrient pollution, making advanced treatment crucial for controlling eutrophication. The plant's inland location and advanced treatment help minimize nutrient loading to this ecologically significant sea.
