UWWTP Sevlievo - Municipal Wastewater Treatment Plant in Sevlievo, Bulgaria

UWWTP Sevlievo is a municipal wastewater treatment plant located in the town of Sevlievo, Gabrovo Province, Bulgaria. The facility serves a population of around 22,579, placing it in the medium agglomeration category under EU classification. The plant is situated in the central-northern part of Bulgaria, near the Rositsa River valley. As a Bulgarian facility, UWWTP Sevlievo operates under the national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations between 10,000 and 150,000 population equivalent, the directive requires secondary treatment as a minimum standard. The regulatory framework ensures appropriate treatment for the community served. The treated effluent from UWWTP Sevlievo likely discharges into a local watercourse that eventually flows into the Rositsa River, a tributary of the Yantra River. The Yantra River drains into the Danube River, which ultimately reaches the Black Sea. This connection highlights the plant's role in protecting downstream water quality and the Black Sea ecosystem.

UWWTP Sevlievo discharges into the Rositsa River basin, which flows into the Yantra River, a major tributary of the Danube. The Danube carries water to the Black Sea, making this plant part of a large transboundary watershed. The Rositsa River supports diverse aquatic life and is important for local agriculture and biodiversity. Proper treatment helps prevent nutrient pollution that could contribute to eutrophication in the Black Sea.
