Overview
UWWTP kkElenite is a secondary treatment plant serving Sveti Vlas, Bulgaria. It discharges 521.80 m³/day of treated wastewater into the Black Sea coastal zone.
UWWTP kkElenite is a municipal wastewater treatment plant located in Sveti Vlas, a coastal town in Burgas Province, Bulgaria. The plant serves a population of approximately 5,012 people and is situated near the Black Sea coast, making it a critical facility for protecting the marine environment. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,332 m³/day and a current discharge volume of 521.80 m³/day, the plant operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into the Black Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The plant's secondary treatment helps reduce organic matter and nutrients, supporting the ecological health of the coastal waters and the broader Black Sea basin, which is an important habitat for diverse marine life.
Environmental context
The plant discharges into the Black Sea, a large inland sea connected to the Mediterranean via the Bosporus Strait. The coastal zone near Sveti Vlas supports tourism and local fisheries, and the Black Sea's unique ecology includes species such as the Black Sea bottlenose dolphin and various migratory fish. Nutrient inputs from wastewater can contribute to eutrophication, so the plant's secondary treatment is essential for maintaining water quality in this sensitive marine environment.
