Hemse avloppsreningsverk - Advanced Wastewater Treatment in Hemse, Gotland, Sweden

Hemse avloppsreningsverk is a municipal wastewater treatment facility located in Hemse, a locality on the island of Gotland, Sweden. The plant serves a population of approximately 1,410 residents and is part of the region's essential water infrastructure. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,100 m³/day and a current discharge volume of 221.34 m³/day, the facility has ample capacity to handle local wastewater loads. The treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea. Gotland's unique limestone geology and sensitive coastal environment make advanced treatment crucial for protecting both groundwater and marine ecosystems. The plant plays a key role in maintaining water quality in the region.

Hemse avloppsreningsverk discharges treated wastewater into the local drainage system on Gotland, which flows into the Baltic Sea. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient pollution. Advanced treatment at this plant helps reduce the risk of eutrophication, supporting the health of coastal habitats and marine life in the region.
