ROWP Statia de epurare Ciucea - Secondary Wastewater Treatment Plant in Vânători, Cluj County, Romania

ROWP Statia de epurare Ciucea is a municipal wastewater treatment plant located in Vânători, a locality within Ciucea commune, Cluj County, Romania. The plant serves a small population of 124 residents, reflecting its role in a rural setting. It operates under Romania's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets treatment standards based on agglomeration size. The plant provides secondary treatment, which is appropriate for small agglomerations under the EU directive. With a designed capacity of 500 m³/day and an actual discharge volume of 27.92 m³/day, the plant operates well below its capacity, indicating it can accommodate future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that ultimately drain into the Crișul Repede River, a tributary of the Körös River system, which flows into the Tisza River and then the Danube. This river network supports diverse aquatic life and is important for regional biodiversity. The plant's operation helps protect downstream water quality in the Tisza-Danube basin.

The plant discharges into local streams that feed the Crișul Repede River, part of the Körös-Tisza-Danube river system. This watershed supports a variety of fish species and provides habitat for migratory birds. The region's aquatic ecosystems benefit from the plant's secondary treatment, which reduces organic pollution and helps maintain water quality in downstream rivers and wetlands.
