Šiaulių m aglomeracija Wastewater Treatment Plant, Jurgeliškiai, Lithuania

Šiaulių m aglomeracija is a wastewater treatment plant located in Jurgeliškiai, within the Šiaulių district municipality of Lithuania. Serving a population of 110,000, it is classified as a large agglomeration under EU standards. The plant is situated inland, approximately 50 km from the Baltic Sea coast, and plays a key role in managing municipal wastewater for the Šiauliai region. As a large agglomeration, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For sensitive areas, tertiary treatment may be mandated. The plant's treatment processes and capacity details are not publicly available, but the regulatory framework ensures compliance with discharge standards to protect the local environment. The treated effluent is likely discharged into the local river system, which drains into the Baltic Sea via the Nemunas River basin or smaller coastal rivers. The plant's operation is critical for maintaining water quality in the region's surface waters and supporting downstream ecosystems, including the Baltic Sea's sensitive marine environment.

The plant discharges into the local watershed, which ultimately flows into the Baltic Sea via the Nemunas River basin or nearby coastal rivers. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The plant's treatment helps reduce nutrient loads, protecting downstream aquatic habitats and supporting the ecological balance of the region's rivers and coastal waters.
