ROWP Comuna Rusii Munti Wastewater Treatment Plant, Rușii-Munți, Mureș, Romania

ROWP Comuna Rusii Munti is a municipal wastewater treatment plant located in Rușii-Munți, a commune in Mureș County, Romania. The plant serves a population of approximately 750 people, reflecting its role in a small rural community. It is situated in the Transylvanian region, an area characterized by rolling hills and agricultural landscapes. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000, but Romania has implemented national regulations that extend similar requirements to smaller communities. The plant has a designed capacity of 1,700 m³/day, with an actual discharge volume of 43.97 m³/day, indicating significant spare capacity. The treated effluent is discharged into a local watercourse that eventually drains into the Mureș River, a major tributary of the Tisza River, which flows into the Danube and ultimately the Black Sea. The Mureș River supports diverse aquatic life and is an important ecological corridor in the Carpathian Basin. Proper treatment helps protect downstream water quality and biodiversity.

The plant discharges into a small stream that feeds into the Mureș River, a key waterway in central Romania. The Mureș River flows westward through the Transylvanian Plateau, joining the Tisza River in Hungary, which then drains into the Danube and the Black Sea. This watershed supports diverse fish species and riparian habitats, making effective wastewater treatment essential for maintaining ecological health in the region.
