ROWP APA CTTA SA PL VINTU DE JOS Wastewater Treatment Plant, Vurpăr, Alba, Romania

ROWP APA CTTA SA PL VINTU DE JOS is a municipal wastewater treatment plant located in Vurpăr, a village in Vințu de Jos commune, Alba County, Romania. The plant serves a small population of 600 residents, reflecting its role in a rural community. It is situated inland, far from coastal areas, and operates under Romanian environmental regulations aligned with EU directives. 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 of this size. With a designed capacity of 1000 m³/day and an actual discharge volume of 22.15 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. Secondary treatment typically involves biological degradation of organic matter followed by sedimentation. The treated effluent is discharged into a local watercourse that ultimately drains into the Mureș River, a major tributary of the Tisza River, which flows into the Danube and then the Black Sea. The plant plays a key role in protecting the local watershed from untreated sewage, supporting water quality in the Mureș basin and downstream ecosystems. Its operation contributes to Romania's compliance with EU water quality standards.

The plant discharges into a small watercourse that flows into the Mureș River, a significant river in Transylvania that joins the Tisza River in Hungary. The Tisza then flows into the Danube, which empties into the Black Sea. This watershed supports diverse aquatic life and is an important ecological corridor. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality in the Mureș basin.
