ROWP Primaria UNGHENI Wastewater Treatment Plant, Ungheni, Romania

ROWP Primaria UNGHENI is a municipal wastewater treatment plant located in Ungheni, Mureș County, Romania. The facility serves a population of approximately 2,860 residents, classifying it as a small agglomeration under Romanian and EU regulations. The plant is situated in the Transylvanian region, an inland area with a continental climate. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies. With a designed capacity of 3,865 m³/day and a current discharge volume of 77.70 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. As a small-scale facility, it is subject to national permitting under Romanian environmental law, which aligns with EU directives. The treated effluent is discharged into a local watercourse that ultimately drains into the Mureș River, a major tributary of the Tisza River, which flows into the Danube and then the Black Sea. The plant plays a key role in protecting the Mureș River basin from nutrient pollution and safeguarding downstream aquatic ecosystems.

The plant discharges into a tributary of the Mureș River, which flows through central Romania before joining the Tisza River in Hungary. The Mureș River supports diverse aquatic life and is an important ecological corridor in the Carpathian Basin. The downstream environment includes agricultural areas and wetlands that benefit from reduced nutrient loads due to secondary treatment. The ultimate destination of the treated water is the Black Sea via the Danube River system.
