Nemencines aglomeracija Wastewater Treatment Plant, Kreivalaužiai, Lithuania

Nemencines aglomeracija is a wastewater treatment plant located in Kreivalaužiai, Vilniaus apskritis, Lithuania. The facility serves a population of approximately 4,500 people, making it a small agglomeration under EU classification. It is situated inland, away from coastal areas, and discharges into local water bodies within the Neris River basin. As a plant serving a population equivalent of 4,500, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The directive mandates secondary treatment for inland freshwater discharges from populations above 2,000, ensuring compliance with environmental standards. The plant's treated effluent ultimately flows into the Neris River, which drains into the Nemunas River and then into the Curonian Lagoon and the Baltic Sea. This waterway supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in protecting downstream water quality.

The plant discharges into the Neris River basin, which flows into the Nemunas River and eventually reaches the Curonian Lagoon and the Baltic Sea. This watershed supports diverse aquatic ecosystems and is important for migratory fish species. The area is ecologically sensitive due to its connection to the Baltic Sea, requiring effective nutrient removal to prevent eutrophication.
