ROWP SC APA CANAL 2000 SA PITESTI CGP COSTESTI Wastewater Treatment Plant, Buzoești, Romania

ROWP SC APA CANAL 2000 SA PITESTI CGP COSTESTI is a municipal wastewater treatment plant located in Buzoești, Argeș County, Romania. The plant serves a population of approximately 9,214 and has a designed capacity of 11,667 m³/day, with a current discharge volume of 641.07 m³/day. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent standards before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Argeș River and then the Danube River, eventually reaching the Black Sea. The plant plays a key role in protecting the downstream aquatic environment from nutrient pollution and organic loading, supporting the ecological health of the Danube basin.

The plant discharges into the Argeș River basin, a tributary of the Danube River, which flows into the Black Sea. The downstream environment supports diverse aquatic life and is part of a major European migratory corridor. The secondary treatment process helps reduce nutrient loads, mitigating eutrophication risks in the Danube Delta and Black Sea coastal waters.
