Vilkijos aglomeracija Wastewater Treatment Plant, Vilkija, Lithuania

Vilkijos aglomeracija is a municipal wastewater treatment plant located in Vilkija, a town in Kauno apskritis, Lithuania. The plant serves a population of 750 and is part of the country's wastewater infrastructure under the EU Urban Waste Water Treatment Directive. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. Its designed capacity is 3000 m³/day, with an actual discharge volume of 104.87 m³/day, indicating significant spare capacity for future growth. The plant discharges treated effluent into the local watershed, which ultimately drains into the Nemunas River basin. The Nemunas River flows into the Curonian Lagoon and then the Baltic Sea, making the plant's operations important for protecting downstream aquatic ecosystems and coastal water quality.

The treated effluent from Vilkijos aglomeracija enters the local water system, which is part of the Nemunas River basin. The Nemunas River is the largest river in Lithuania and flows into the Curonian Lagoon, a sensitive coastal ecosystem that supports diverse aquatic life and migratory birds. The lagoon connects to the Baltic Sea, so effective wastewater treatment is crucial for preventing nutrient pollution and maintaining ecological balance in these downstream waters.
