Overview
UWWTP Blagoevgrad serves approximately 79,000 people in Blagoevgrad, Bulgaria. The plant operates under EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations of this scale.
UWWTP Blagoevgrad is a municipal wastewater treatment facility located in the southern industrial zone of Blagoevgrad, Bulgaria, along Pokrovnisko Shose. It serves an estimated population of 78,689, classifying it as a medium-to-large agglomeration under EU standards. The plant is situated inland, more than 50 km from the Black Sea coast, and its treated effluent likely discharges into a local river system. As a Bulgarian facility, the plant is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations with a population equivalent (PE) above 10,000. For plants serving over 15,000 PE in sensitive areas, tertiary treatment may be mandated. The regulatory framework ensures a minimum level of treatment to protect receiving waters. Blagoevgrad lies in the Struma River basin, which flows southward into Greece and eventually the Aegean Sea. The Struma River supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in maintaining water quality in this transboundary river system.
Environmental context
UWWTP Blagoevgrad is located in the Struma River basin, a major watercourse that flows from western Bulgaria into Greece and discharges into the Aegean Sea. The Struma River supports diverse aquatic ecosystems and is an important migratory corridor for fish and other species. The plant's treated effluent contributes to the river's flow and must meet EU standards to prevent eutrophication and protect downstream habitats, including ecologically sensitive areas in the lower reaches.
