ROWP PRIMARIA ANINOASA Wastewater Treatment Plant, Aninoasa, Argeș, Romania

ROWP PRIMARIA ANINOASA is a municipal wastewater treatment plant located in Aninoasa, Argeș County, Romania. The plant serves a small population of approximately 120 residents, reflecting its role in a rural or small-town setting within the southern Carpathian foothills. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 2,000. With a designed capacity of 350 m³/day and an actual discharge volume of 27.02 m³/day, the plant operates well below its capacity, indicating low hydraulic loading relative to its design. The treated effluent is discharged into local watercourses that ultimately drain into the Argeș River, a tributary of the Danube. The Danube then flows into the Black Sea, making this plant part of a large transboundary river basin. The surrounding area includes agricultural land and forests, and the plant's discharge contributes to the overall water quality in the Argeș catchment.

The plant discharges into a local tributary of the Argeș River, which flows southward to join the Danube River before reaching the Black Sea. The Argeș basin supports diverse aquatic life and is used for irrigation and recreation. Downstream ecosystems include wetlands and floodplain forests that rely on good water quality. The plant's secondary treatment helps reduce organic pollution and protect these habitats.
