Overview
ROWP Compania de Apa Oltenia SA Calafat serves Vidin, Bulgaria, treating wastewater for approximately 15,880 people. The plant operates under EU regulations for medium-sized agglomerations.
ROWP Compania de Apa Oltenia SA Calafat is a wastewater treatment plant located in the northern industrial zone of Vidin, Bulgaria, near the border with Romania. It serves a population of around 15,880, classifying it as a medium-sized agglomeration under EU standards. The plant is part of the regional water utility Compania de Apa Oltenia SA. As an EU member state, Bulgaria implements the Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant is expected to meet these standards to protect downstream water quality. The facility's design capacity and operational status are not publicly documented, but regulatory compliance ensures appropriate treatment levels. The plant discharges treated wastewater into the Danube River basin, which ultimately flows into the Black Sea. The Danube is a major European waterway supporting diverse aquatic ecosystems and providing water for agriculture and industry. Proper treatment at this plant helps reduce nutrient and pollutant loads, contributing to the ecological health of the Danube Delta and the Black Sea coastal environment.
Environmental context
The plant discharges into the Danube River basin, which drains into the Black Sea via the Danube Delta. This region supports rich biodiversity, including migratory fish and bird species. Effective wastewater treatment is critical to prevent eutrophication and protect the sensitive delta ecosystem, which is a key ecological corridor in southeastern Europe.
