Overview
UWWTP Momchilgrad serves the city of Momchilgrad in Bulgaria's Kardzhali province. This advanced treatment plant handles wastewater for a population of 10,704 with a designed capacity of 11,268 m³/day.
UWWTP Momchilgrad is a municipal wastewater treatment facility located in Momchilgrad, a town in the Kardzhali province of southern Bulgaria. The plant serves a population of approximately 10,704 people and has a designed capacity of 11,268 cubic meters per day, with a reported discharge volume of 942.12 cubic meters per day. It operates under Bulgaria's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. As a facility serving a medium-sized agglomeration (between 10,000 and 15,000 population equivalent), it is subject to EU standards that mandate secondary treatment as a minimum, with tertiary or advanced treatment required in sensitive areas. The plant's advanced treatment level suggests it meets stringent effluent quality standards. The treated wastewater is discharged into the local watershed, which ultimately drains into the Aegean Sea via the Arda River system. The plant plays a crucial role in protecting downstream water quality and supporting the ecological health of the region's rivers and coastal waters. Its operation contributes to the preservation of aquatic habitats and the overall environmental integrity of the area.
Environmental context
The plant discharges into the Arda River basin, which flows through southern Bulgaria and northern Greece before emptying into the Aegean Sea. This watershed supports diverse aquatic life and is an important ecological corridor. The advanced treatment helps minimize nutrient and pollutant loads, protecting downstream ecosystems and the sensitive coastal environment of the Aegean.
