Environmental context
The plant discharges into the Kranto River, a tributary of the Nemunas River, which flows through Lithuania and into the Curonian Lagoon, a sensitive coastal lagoon connected to the Baltic Sea. The Nemunas basin supports diverse aquatic habitats and is an important migratory corridor for fish. Nutrient loading from wastewater can contribute to eutrophication in the lagoon, making secondary treatment essential for ecological balance.
