ROWP AIDR SC APA SERVICE SA GIURGIU BOLINTIN VALE Wastewater Treatment Plant, Bolintin-Vale, Romania

ROWP AIDR SC APA SERVICE SA GIURGIU BOLINTIN VALE is a municipal wastewater treatment plant located in Bolintin-Vale, Giurgiu County, Romania. The facility serves a population of approximately 3,110 residents, classifying it as a small agglomeration under Romanian and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges. With a designed capacity of 11,200 m³/day, the plant has significant headroom to accommodate future growth. The actual discharge volume is 515.78 m³/day, indicating a utilization rate well below capacity. The plant is operated under the Romanian national regulatory framework, which transposes EU directives and is overseen by the National Administration of Romanian Waters. The treated effluent is discharged into local water bodies that ultimately drain into the Danube River basin. The Danube is a major European waterway flowing into the Black Sea, supporting diverse aquatic ecosystems and serving as a critical migratory corridor for fish and birds. The plant's secondary treatment helps protect downstream water quality in the Danube and the Black Sea coastal zone.

The plant discharges into the Arges River basin, a tributary of the Danube River. The Danube flows eastward through Romania and into the Black Sea via the Danube Delta, a vast wetland of ecological importance. The delta supports diverse aquatic life, including sturgeon and migratory birds. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in this sensitive downstream ecosystem.
