Ignalinos aglomeracija Wastewater Treatment Plant - Ignalina, Lithuania

Ignalinos aglomeracija is an advanced wastewater treatment plant located in Ignalina, Utenos apskritis, Lithuania. The facility serves a population of 3,600, classifying it as a small agglomeration under EU regulations. It is situated inland, away from coastal areas, and plays a key role in managing local wastewater. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 7,000 m³/day and a current discharge volume of 741.02 m³/day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local water bodies that eventually drain into the Nemunas River basin and the Baltic Sea. By providing advanced treatment, the plant helps protect downstream ecosystems, including sensitive freshwater habitats and the Baltic Sea marine environment, from nutrient pollution and other contaminants.

The plant discharges into local streams that are part of the Nemunas River basin, which flows into the Curonian Lagoon and ultimately the Baltic Sea. This watershed supports diverse aquatic life and is ecologically sensitive to nutrient loading. Advanced treatment at this facility helps reduce the risk of eutrophication in downstream waters.
