ROWP Rodna Wastewater Treatment Plant, Rodna, Bistrița-Năsăud, Romania

ROWP Rodna is a municipal wastewater treatment plant located in Rodna, a town in Bistrița-Năsăud County, Romania. The plant serves a population of about 2,982 and has a designed capacity of 9,324 m³ per day, indicating it is sized for a small agglomeration. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent quality standards. The treated effluent is discharged into local watercourses that are part of the Someș River basin, which flows westward through Transylvania and eventually into the Tisza River and the Danube. The plant plays a key role in protecting the water quality of the Someș catchment and downstream ecosystems, including the Danube Delta, a region of high ecological importance.

ROWP Rodna discharges into the Someș River basin, which drains into the Tisza River and ultimately the Danube River before reaching the Black Sea. The Someș catchment supports diverse aquatic life and is used for agriculture, fisheries, and recreation. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding downstream water quality and the ecological health of the Danube Delta, a vital wetland ecosystem.
