Overview
UWWTP Nesebar Ravda Slanchev bryag serves 181,653 people in the Burgas region of Bulgaria. The plant is located near the Black Sea coast and operates under EU Urban Waste Water Treatment Directive standards.
UWWTP Nesebar Ravda Slanchev bryag is a municipal wastewater treatment plant serving the towns of Nesebar, Ravda, and Slanchev Bryag in the Burgas Province of Bulgaria. Located near the town of Aheloy, the plant handles wastewater from a population equivalent of 181,653, classifying it as a large agglomeration under EU regulations. The facility is situated within 50 km of the Black Sea coast, making its discharge management critical for coastal water quality. As a Bulgarian plant serving over 150,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires at least secondary treatment for such agglomerations. The directive also mandates more advanced treatment if the discharge enters sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a substantial infrastructure investment to handle the seasonal tourist population of the Black Sea resorts. The treated effluent from the plant ultimately reaches the Black Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The Burgas Bay area supports diverse marine life and is an important ecological zone. Proper treatment helps protect coastal ecosystems, including fish spawning grounds and migratory bird habitats along the Via Pontica flyway.
Environmental context
The plant discharges into the Black Sea via the Burgas Bay, a coastal area with significant ecological importance. The Black Sea is a semi-enclosed basin with limited vertical mixing, making it vulnerable to eutrophication from nutrient inputs. The Burgas region hosts the Burgas Wetlands, a complex of lakes and marshes that support diverse bird species and aquatic life. Effective wastewater treatment is essential to prevent algal blooms and maintain water quality for tourism and fisheries.
