ROWP PRIMARIA ACATARI Wastewater Treatment Plant, Stejeriș, Mureș County

ROWP PRIMARIA ACATARI is a wastewater treatment plant located in Stejeriș, a village within the Acățari commune in Mureș County, Romania. It serves a small population of 221 residents as part of the Târgu Mureș metropolitan area. The plant operates with primary treatment, which involves physical processes like sedimentation to remove suspended solids. As a small-scale facility in Romania, the plant is subject to national regulations aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations under 2,000 population equivalent, the directive requires appropriate treatment, which primary treatment fulfills. The plant's designed capacity of 1000 m³/day indicates it can handle peak flows, while the current discharge volume of 6.16 m³/day reflects the low population served. The treated effluent is discharged into local watercourses that eventually drain into the Mureș River, a major tributary of the Tisza River, which flows into the Danube and ultimately the Black Sea. The plant plays a role in protecting the local watershed from untreated sewage, supporting water quality in the region's aquatic ecosystems.

The plant discharges into small streams within the Mureș River basin. The Mureș River flows westward through Transylvania, joining the Tisza River in Hungary, which then drains into the Danube and the Black Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. Primary treatment reduces suspended solids but does not remove nutrients, so downstream water bodies may be sensitive to organic loading, particularly during low-flow periods.
