It serves a population of 2,841, classifying it as a small agglomeration under Bulgarian and EU regulations. The plant is situated close to the coast, within 10 km of the Black Sea. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. Its designed capacity is 1,080 cubic meters per day, and it currently treats an average daily volume of 80.96 cubic meters, indicating significant spare capacity. As a Bulgarian facility, it operates under national legislation transposing the EU directive, which mandates appropriate treatment levels based on receiving water sensitivity and population size. 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 advanced treatment helps protect the coastal marine environment, supporting biodiversity and tourism in the region. The surrounding area includes the Shabla Lake complex, an important wetland for migratory birds, and the plant plays a key role in preserving local water quality.
