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

ROWP Chintelnic is a municipal wastewater treatment facility located in the village of Chintelnic, part of the Șieu-Măgheruș commune in Bistrița-Năsăud County, Romania. The plant serves a small population of 292 residents, reflecting its role in a rural community. It operates as a secondary treatment plant, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 1000 m³ per day and currently treats an average daily flow of 30.24 m³, indicating a low utilization rate. As a Romanian facility, it falls under the national implementation of the EU directive, which mandates secondary treatment for discharges into freshwater bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse, likely a tributary of the Someș River or the Mureș River, both of which are part of the Tisza River basin that ultimately drains into the Danube River and then the Black Sea. The plant plays a key role in protecting local water quality and the downstream aquatic ecosystem in the Transylvanian region.

The plant discharges into a small watercourse in the Transylvanian Plateau, which flows into the Someș River or Mureș River, both part of the Tisza River basin. This basin drains into the Danube River and ultimately the Black Sea. The surrounding area is predominantly agricultural, so the plant helps reduce nutrient and organic pollution that could otherwise contribute to eutrophication in downstream water bodies. The local watershed supports diverse aquatic life and is important for regional biodiversity.
