ROWP SC APA TARNAVEI MARI SA SUC DUMBRAVENI ev Alma - Secondary Wastewater Treatment Plant in Alma, Sibiu, Romania

ROWP SC APA TARNAVEI MARI SA SUC DUMBRAVENI ev Alma is a wastewater treatment plant located in Alma, a commune in Sibiu County, Romania. The plant serves a population of 490 and has a designed capacity of 2100 m³/day, with a current discharge volume of 28.52 m³/day. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent above 2000, but smaller plants like this one may also apply secondary treatment to meet local environmental objectives. The treated effluent is discharged into local watercourses that eventually drain into the Tarnava Mare River, a tributary of the Mures River, which flows into the Tisza River and ultimately the Danube River and the Black Sea. The plant plays a role in protecting the water quality of the Tarnava Mare basin, which supports diverse aquatic life and is used for agricultural and recreational purposes.

The plant discharges into the Tarnava Mare River basin, which flows into the Mures River, a major tributary of the Tisza River. The Tisza joins the Danube, which empties into the Black Sea. The Tarnava Mare watershed supports diverse aquatic ecosystems and is important for local agriculture and biodiversity. Secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality.
