Overview
Ukmerges aglomeracija serves 25,000 people in Ukmergė, Lithuania. The plant operates under EU Urban Waste Water Treatment Directive standards for medium agglomerations.
Ukmerges aglomeracija is a municipal wastewater treatment plant located in Ukmergė, Vilniaus apskritis, Lithuania. It serves a population of approximately 25,000, classifying it as a medium agglomeration under EU regulations. As a plant in an EU member state, Ukmerges 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 designated as sensitive areas. The plant's treated effluent discharges into the local watershed, which ultimately drains into the Neris River basin and then into the Baltic Sea. This connection to the Baltic Sea underscores the importance of effective nutrient removal to protect the marine environment from eutrophication.
Environmental context
The plant's discharge enters the Neris River basin, a major tributary of the Nemunas River, which flows into the Curonian Lagoon and then the Baltic Sea. The Baltic Sea is a semi-enclosed sea sensitive to nutrient pollution, making effective wastewater treatment critical for reducing nitrogen and phosphorus loads that contribute to algal blooms and hypoxia.

The treated effluent is discharged into the local watershed, which flows into the Neris River basin and ultimately reaches the Baltic Sea.
As a medium agglomeration (serving 25,000 people), the plant is required to provide at least secondary treatment under the EU Urban Waste Water Treatment Directive (91/271/EEC). If the receiving waters are sensitive, tertiary treatment may be required.
In Lithuania, plants serving 25,000 people typically provide secondary biological treatment, often with nutrient removal to meet EU standards for discharge into sensitive water bodies like the Baltic Sea basin.
