ROWP BAIA Wastewater Treatment Plant, Baia, Suceava County, Romania

ROWP BAIA is a municipal wastewater treatment plant located in Baia, Suceava County, Romania. It serves a small population of 203 residents, reflecting the rural character of the area. The plant is part of Romania's national wastewater infrastructure, which is aligned with the European Union's Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard required by the EU directive for agglomerations with a population equivalent (PE) between 2,000 and 10,000. Although the population served is below this threshold, the plant's designed capacity of 6,000 m³/day suggests it may also handle industrial or seasonal loads. The current discharge volume of 47.11 m³/day indicates low utilization relative to capacity. Treated effluent from ROWP BAIA is discharged into local watercourses that ultimately drain into the Siret River, a major tributary of the Danube. The Danube then flows into the Black Sea. The plant plays a role in protecting the Siret basin from untreated wastewater, supporting aquatic life and downstream water quality in the Danube Delta ecosystem.

The plant discharges into local streams that feed the Siret River, which flows into the Danube and eventually the Black Sea. The Siret basin supports diverse aquatic habitats and is important for migratory fish species. The Black Sea coastal zone is ecologically sensitive, with nutrient pollution from upstream sources contributing to eutrophication. Proper treatment at ROWP BAIA helps reduce nutrient loads to this downstream environment.
