Overview
UWWTP Kozloduy serves the town of Kozloduy in Vratsa Province, Bulgaria. The plant operates under the EU Urban Waste Water Treatment Directive, which sets treatment standards for agglomerations of this scale.
UWWTP Kozloduy is a municipal wastewater treatment facility located in Kozloduy, a town in Vratsa Province, northwestern Bulgaria. The plant serves the local population as part of the region's wastewater infrastructure, contributing to public health and environmental protection in the Danube River basin. As a Bulgarian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which Bulgaria adopted upon accession. This directive requires secondary treatment for discharges to freshwater and estuaries, with tertiary treatment in sensitive areas. The plant's compliance with these standards ensures treated effluent meets regulatory requirements before discharge. The treated wastewater from UWWTP Kozloduy ultimately flows into the Danube River via local tributaries, as Kozloduy lies within the Danube basin. The Danube is Europe's second-longest river, draining into the Black Sea. The plant plays a key role in protecting downstream water quality and the ecological health of the Danube Delta, a region of high biodiversity.
Environmental context
UWWTP Kozloduy discharges into the Danube River basin, which flows eastward into the Black Sea. The Danube supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's treatment helps reduce nutrient and pollutant loads, safeguarding the ecological balance of the lower Danube and the Black Sea coastal zone.
