GIMO AVLOPPSRENINGSVERK - Advanced Wastewater Treatment in Ingolsbenning, Sweden

GIMO AVLOPPSRENINGSVERK is an advanced wastewater treatment plant located in Ingolsbenning, within Norbergs kommun, Västmanlands län, Sweden. The plant serves a population of approximately 4,093 people, reflecting a small to medium-sized agglomeration typical of rural Swedish communities. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 6,000 m³/day, with an actual discharge volume of 642.52 m³/day, indicating ample reserve capacity. As an advanced treatment facility, it likely employs processes such as biological nutrient removal or chemical precipitation to meet stringent effluent standards. The treated effluent is discharged into local watercourses that eventually drain into the Baltic Sea via the Dalälven river system. The plant's inland location, over 50 km from the coast, reduces direct marine impact, but its discharge contributes to the overall nutrient load in the Baltic Sea, a sensitive water body affected by eutrophication. The advanced treatment helps minimize this impact.

The plant discharges into local streams that flow into the Dalälven river, which ultimately reaches the Baltic Sea. The Baltic Sea is a brackish water body highly sensitive to nutrient pollution, leading to algal blooms and oxygen depletion. Advanced treatment at this plant reduces phosphorus and nitrogen loads, supporting the health of downstream aquatic ecosystems.
