Jarvso ARV is a wastewater treatment plant located in Kramsta, within Ljusdals kommun, Gävleborgs län, Sweden. The plant serves a population of around 1,898 people, placing it in the small agglomeration category under Swedish and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for smaller agglomerations. With a designed capacity of 3,000 m³/day and a current discharge volume of approximately 298 m³/day, the facility operates well within its capacity, ensuring effective treatment. The treated effluent is discharged into the local water system, which ultimately drains into the Baltic Sea via the Ljusnan River and its tributaries. This advanced treatment helps protect the sensitive aquatic ecosystems of the region, supporting biodiversity and water quality in the downstream environment.
Environmental context
The plant discharges into the Ljusnan River basin, which flows through Gävleborgs län and empties into the Bothnian Sea, part of the Baltic Sea. The Baltic Sea is a brackish water body with limited water exchange, making it sensitive to nutrient pollution. Advanced treatment at Jarvso ARV reduces nutrient loads, helping to prevent eutrophication and protect the diverse aquatic life in the river and coastal waters.
