Kursenu aglomeracija Wastewater Treatment Plant, Micaičiai, Lithuania

Kursenu aglomeracija is a wastewater treatment plant located in Micaičiai, a village in the Šiaulių apskritis region of Lithuania. The plant serves a population of approximately 9,000 people, classifying it as a medium-sized agglomeration under EU regulations. It plays a key role in managing municipal wastewater for the local community. As a plant serving between 2,000 and 10,000 population equivalent, Kursenu aglomeracija is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum standard. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures appropriate treatment levels. The treated effluent from Kursenu aglomeracija is discharged into local water bodies that eventually drain into the Baltic Sea via the Venta River basin. The plant's location inland, more than 50 km from the coast, reduces direct marine impact. The surrounding watershed supports diverse aquatic life and is part of Lithuania's broader water management system.

The plant discharges into the Venta River basin, which flows into the Baltic Sea. The Venta River supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The watershed is characterized by agricultural and forested areas, and the plant's operations help protect downstream water quality in the Baltic Sea.
