Jonavos aglomeracija Wastewater Treatment Plant, Jonava, Lithuania

Jonavos aglomeracija is a municipal wastewater treatment plant located in Jonava, Kauno apskritis, Lithuania. It serves a population of around 26,100, classifying it as a medium-sized agglomeration under EU standards. The plant is situated in the central part of the country, near the Neris River basin. As a facility in an EU member state, Jonavos aglomeracija 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 sensitive to eutrophication. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with national and EU water quality goals. The treated effluent from Jonavos aglomeracija is discharged into the local watershed, which ultimately drains into the Neris River and then into the Nemunas River, flowing into the Curonian Lagoon and the Baltic Sea. This downstream chain supports diverse aquatic ecosystems and is important for regional biodiversity. The plant plays a key role in protecting these water bodies from nutrient pollution and maintaining ecological balance.

Jonavos aglomeracija 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 a variety of fish and bird species, and the lagoon is an important migratory stopover. The plant's operations help reduce nutrient loading, which is critical for preventing eutrophication in these sensitive coastal waters.
