ROWP SC APA TARNAVEI MARI SA SUC DUMBRAVENI Wastewater Treatment Plant, Dumbrăveni, Sibiu

ROWP SC APA TARNAVEI MARI SA SUC DUMBRAVENI is a municipal wastewater treatment plant located at 6, Strada Cetății, Dumbrăveni, Sibiu, Romania. The plant serves a population of approximately 1,000 people and has a designed capacity of 2,000 m³/day, with a current discharge volume of 181.70 m³/day. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring compliance with EU effluent standards before discharge. The treated effluent is released into the local watershed, which ultimately drains into the Târnava Mare River, a tributary of the Mureș River, and then into the Tisza River and the Danube River basin. The plant plays a key role in protecting the water quality of the Târnava Mare River and downstream ecosystems, supporting aquatic life and reducing nutrient pollution in the Danube Basin.

The plant discharges into the Târnava Mare River, which flows into the Mureș River, a major tributary of the Tisza River, and eventually reaches the Danube River and the Black Sea. The Târnava Mare River supports diverse aquatic life and is part of a sensitive watershed that requires careful management to prevent eutrophication and maintain ecological balance. The plant's secondary treatment helps reduce organic and nutrient loads, protecting downstream habitats and water quality.
