Overview
UWWTP Veliki Preslav serves the town of Veliki Preslav in Shumen Province, Bulgaria, treating wastewater for approximately 18,800 residents. The plant operates under Bulgaria's implementation of the EU Urban Waste Water Treatment Directive.
UWWTP Veliki Preslav is a municipal wastewater treatment facility located in Veliki Preslav, a town in Shumen Province, northeastern Bulgaria. The plant serves a population of around 18,800 people, classifying it as a medium-sized agglomeration under EU regulations. Its location inland, away from the coast, influences its discharge and environmental management. As a Bulgarian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are sensitive areas. The regulatory framework ensures compliance with national and EU standards for effluent quality. The treated wastewater is discharged into local water bodies that eventually drain into the Black Sea via the Kamchia River basin. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems, and safeguarding downstream environments, including the Black Sea coastal zone.
Environmental context
The plant's treated effluent enters local streams that flow into the Kamchia River, a major watercourse in northeastern Bulgaria. The Kamchia River drains into the Black Sea, an ecologically sensitive semi-enclosed sea with limited water exchange. The region supports diverse aquatic life, including migratory fish species, and the plant's operations help reduce nutrient loading that could contribute to eutrophication in coastal waters.
Frequently asked questions
UWWTP Veliki Preslav is located in the town of Veliki Preslav, Shumen Province, northeastern Bulgaria. The facility serves the municipal wastewater needs of the town and surrounding area.
The plant serves approximately 18,800 people, classifying it as a medium-sized agglomeration under EU classification. This population size determines the required treatment standards under the EU Urban Waste Water Treatment Directive.
Treated wastewater from the plant is discharged into local water bodies that flow into the Kamchia River, which ultimately reaches the Black Sea. The discharge is regulated to meet Bulgarian and EU standards for effluent quality.
As a Bulgarian wastewater treatment plant, UWWTP Veliki Preslav operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive mandates secondary treatment for agglomerations of this size and may require tertiary treatment if the receiving waters are sensitive areas.
For agglomerations of this size, the EU Urban Waste Water Treatment Directive requires at least secondary treatment (biological treatment). In Bulgaria, plants typically implement activated sludge or similar processes to meet effluent standards, with possible nutrient removal if discharging into sensitive areas.
