Traku Lentvario aglomeracija Wastewater Treatment Plant, Lentvaris, Lithuania

Traku Lentvario aglomeracija is a wastewater treatment plant located in Lentvaris, Vilnius County, Lithuania. It serves a population of approximately 11,000 people, classifying it as a medium-sized agglomeration under EU standards. The plant is situated in the eastern part of the country, near the capital Vilnius, and is part of the regional wastewater infrastructure managed by local authorities. As a facility operating within the European Union, the plant is subject to the Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes and capacity are designed to meet these regulatory standards, ensuring compliance with EU environmental norms. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Neris River basin, a major tributary of the Nemunas River. The Nemunas flows into the Curonian Lagoon and then the Baltic Sea. This downstream connection highlights the plant's role in protecting the ecological health of the Neris and Nemunas river systems, which support diverse aquatic life and are important for regional biodiversity.

The plant discharges into the Neris River basin, which flows into the Nemunas River, the largest river in Lithuania. The Nemunas empties into the Curonian Lagoon and ultimately the Baltic Sea. This watershed supports diverse aquatic ecosystems, including fish spawning grounds and migratory bird habitats. The plant's operations help maintain water quality in these downstream environments, which are ecologically sensitive and important for regional biodiversity.
