ROWP Primaria Nadrag Wastewater Treatment Plant, Nădrag, Romania

ROWP Primaria Nadrag is a wastewater treatment plant located on Strada Metalurgiștilor in Nădrag, a town in Timiș County, western Romania. The plant serves a population of 2,117, classifying it as a small agglomeration under Romanian and EU regulations. The plant provides primary treatment, which involves physical processes like sedimentation to remove settleable solids. As a small agglomeration in Romania, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into freshwater bodies. The plant's designed capacity of 1,726 m³/day indicates it can handle peak flows, with current discharge at 269.48 m³/day. The treated effluent from ROWP Primaria Nadrag is discharged into local watercourses that drain into the Timiș River basin, eventually reaching the Danube River and the Black Sea. The plant plays a key role in protecting the local watershed from untreated sewage, supporting aquatic life and downstream water quality.

The plant discharges into the Timiș River basin, which flows into the Danube River and ultimately the Black Sea. This watershed supports diverse aquatic ecosystems and is important for regional biodiversity. The primary treatment level reduces suspended solids but does not remove nutrients, so downstream water bodies may be sensitive to nutrient loading.
