ROWP Compania de Apa Arad Statia de epurare Siria - Secondary Wastewater Treatment in Șiria, Romania

ROWP Compania de Apa Arad Statia de epurare Siria is a wastewater treatment plant located in Șiria, Arad County, Romania. The facility serves a small population of 30 and is situated inland, away from coastal areas. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids. The plant operates under Romania's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this scale. The plant is operating well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Mureș River basin, part of the larger Tisza River system, which flows into the Danube River and ultimately the Black Sea. The plant plays a role in protecting the local watershed and downstream aquatic ecosystems from untreated pollution.

The plant discharges into the local drainage network within the Mureș River basin, which flows into the Tisza River, a major tributary of the Danube. The Danube then empties into the Black Sea. The surrounding area is characterized by agricultural land and small settlements, making the plant important for preventing nutrient pollution and maintaining water quality in downstream rivers and the Black Sea ecosystem.
