Overview
UWWTP kkRousalka is a closed secondary treatment plant near Sveti Nikola, Bulgaria. It served the coastal area of Kavarna in Dobrich Province.
UWWTP kkRousalka is a former wastewater treatment plant located near Sveti Nikola, a coastal settlement in Kavarna municipality, Dobrich Province, Bulgaria. The plant was designed to serve the local community along the Black Sea coast. The plant provided secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for coastal discharges. Although the plant is now closed, its design reflects the regulatory framework for Bulgarian wastewater infrastructure, which aligns with EU directives for agglomerations of this scale. The plant's location near the Black Sea means its treated effluent would have discharged into the coastal waters of the Black Sea basin. The Black Sea is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Proper wastewater treatment is critical to protect marine ecosystems and support tourism in the region.
Environmental context
The plant is situated less than 10 km from the Black Sea coast, a semi-enclosed sea with limited water exchange and high ecological sensitivity. Treated wastewater would have discharged into the Black Sea basin, which supports diverse marine life including fish, mollusks, and migratory birds. Nutrient loading from untreated or inadequately treated wastewater can contribute to eutrophication and hypoxia in coastal zones, affecting both biodiversity and local tourism-dependent economies.
