ROWP Comuna Gheorghe Doja Wastewater Treatment Plant, Satu Nou, Romania

ROWP Comuna Gheorghe Doja is a wastewater treatment plant located in Satu Nou, within the Gheorghe Doja commune, part of the Târgu Mureș metropolitan area in Mureș County, Romania. The plant serves a small population of 32 residents, reflecting its role in a rural setting. The plant operates at primary treatment level, which involves physical processes such as sedimentation to remove solids. With a designed capacity of 500 m³/day and an actual discharge volume of 0.93 m³/day, the plant has significant spare capacity. Under Romanian and EU regulations, small agglomerations like this are subject to the Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the receiving water body sensitivity. The treated effluent is discharged into local watercourses that eventually drain into the Mureș River, a tributary of the Tisza River, which flows into the Danube and ultimately the Black Sea. The plant helps protect the local watershed from untreated sewage, supporting water quality in the Mureș River basin.

The plant discharges into small streams within the Mureș River basin, which flows into the Tisza River and then the Danube, reaching the Black Sea. The Mureș River supports diverse aquatic life and is an important ecological corridor in the Carpathian Basin. The plant's primary treatment reduces suspended solids and organic load, mitigating pollution in the sensitive downstream environment.
