ROWP Agris Wastewater Treatment Plant, Agriș, Satu Mare, Romania

ROWP Agris is a municipal wastewater treatment plant located in Agriș, Satu Mare County, Romania. It serves a small population of 215 residents, reflecting the rural character of the area. The plant is situated in the northwestern part of Romania, near the border with Hungary. The facility provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 1,200 m³/day indicates the plant is sized to handle peak flows, though current discharge volume is 66.53 m³/day. As a Romanian plant, it operates under national transposition of EU directives, with oversight from the Romanian Waters Authority. The treated effluent likely discharges into local watercourses that drain into the Someș River, a tributary of the Tisza River, which ultimately flows into the Danube River and the Black Sea. The plant plays a key role in protecting local water quality and the downstream aquatic ecosystem.

The plant's discharge enters the local hydrographic network within the Someș River basin, which flows into the Tisza River and then the Danube before reaching the Black Sea. The region supports diverse aquatic life and is part of an important migratory corridor for fish species. The secondary treatment provided helps reduce organic pollutants and nutrients, safeguarding the ecological health of downstream waters.
