ROWP Primaria Dragus Wastewater Treatment Plant, Drăguș, Brașov, Romania

ROWP Primaria Dragus is a municipal wastewater treatment plant located in Drăguș, a commune in Brașov County, Romania. The facility serves a population of 697 and operates with a designed capacity of 1000 cubic meters per day, currently discharging approximately 230.14 cubic meters per day of treated effluent. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. Although the plant serves fewer than 2,000 people, it still meets the secondary treatment benchmark, ensuring organic matter and suspended solids are reduced before discharge. The treated wastewater is discharged into local watercourses that ultimately drain into the Olt River basin, a major tributary of the Danube. The Danube then flows into the Black Sea. The plant's location in the Carpathian foothills means the receiving waters support diverse aquatic life and are part of a region known for its natural landscapes and tourism.

The plant discharges into the Olt River basin, which flows southward to join the Danube River. The Danube carries the effluent to the Black Sea, a semi-enclosed sea with sensitive ecosystems. The surrounding area is in the Carpathian Mountains, where water quality is important for local biodiversity and downstream communities. The secondary treatment process helps protect these waters from excessive organic pollution.
