ROWP Vascau Wastewater Treatment Plant, Vașcău, Bihor County

ROWP Vascau is a municipal wastewater treatment plant located in Vașcău, a town in Bihor County, western Romania. The plant serves a population of 279 and is part of the local sanitation infrastructure managed by the Apa Canal or similar regional operator. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 10,000. With a designed capacity of 1000 m³/day and an actual discharge volume of 103.68 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into a local watercourse that eventually drains into the Crișul Negru River, a tributary of the Körös River system, which flows into the Tisza River and ultimately the Danube River and Black Sea. The plant plays a key role in protecting the local watershed from untreated sewage pollution.

The plant discharges into a small tributary of the Crișul Negru River, which flows through the Apuseni Mountains into the Körös River system. This watershed supports diverse aquatic life and is part of the larger Tisza-Danube basin. The secondary treatment provided by the plant helps reduce organic load and nutrient pollution, safeguarding downstream water quality and ecological health in the region.
