ROWP Ieud Wastewater Treatment Plant, Ieud, Maramureș, Romania

ROWP Ieud is a municipal wastewater treatment plant located in the village of Ieud, Maramureș County, Romania. The facility serves a small population of around 840 residents, reflecting its role in a rural community. The plant is situated in the historical region of Transylvania, within the Carpathian Mountains foothills. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) between 2,000 and 10,000. Although the population served is below 2,000, the plant's design capacity of 1,000 m³/day suggests it is built to accommodate future growth or seasonal variations. The facility operates under Romania's national water legislation, which transposes EU directives. The treated effluent is discharged into a local watercourse that eventually drains into the Someș River, a tributary of the Tisza River, which flows into the Danube River and ultimately the Black Sea. The plant plays a crucial role in protecting the local watershed from untreated sewage, supporting water quality in the Someș basin and downstream ecosystems.

The plant discharges into a small tributary of the Someș River, which flows through Maramureș County. The Someș River is part of the Tisza River basin, a major tributary of the Danube. The downstream environment includes the Tisza floodplains, which support diverse aquatic life and are important for migratory birds. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting the ecological health of the Someș and Tisza rivers.
