ROWP Statia de epurare SC Local Prest Astileu - Primary Wastewater Treatment in Bihor, Romania

ROWP Statia de epurare SC Local Prest Astileu is a municipal wastewater treatment plant located in Aștileu, Bihor County, Romania. The facility serves a small population of 206 residents, reflecting its role in a rural or peri-urban community. The plant is situated at an elevation in the Apuseni Mountains foothills, with coordinates 47.021°N, 22.395°E. The plant provides primary treatment, which involves physical sedimentation and screening to remove settleable solids. With a designed capacity of 2,000 m³/day, the current discharge volume of 324.53 m³/day indicates low utilization. As a Romanian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations above 2,000 population equivalent. Given its small scale, the plant's primary treatment level is typical for communities under the directive's threshold. The treated effluent is discharged into local watercourses that drain into the Crișul Repede River, a tributary of the Tisza River, which flows into the Danube and ultimately the Black Sea. The plant's operation helps protect the local watershed and downstream ecosystems from untreated sewage.

The plant discharges into the Crișul Repede River basin, which flows through Bihor County into Hungary, joining the Tisza River. The Tisza is a major tributary of the Danube, which empties into the Black Sea. The local watershed supports diverse aquatic life and is part of the larger Carpathian Basin ecosystem. The plant's primary treatment reduces suspended solids but does not remove nutrients, so downstream water quality depends on dilution and natural attenuation.
