ROWP SC GOS COM SA _sector Bodoc Wastewater Treatment Plant, Zălan, Covasna County

ROWP SC GOS COM SA _sector Bodoc is a municipal wastewater treatment plant located in Zălan, a village in the Bodoc commune of Covasna County, Romania. The plant serves a small population of 187 residents, reflecting its role in a rural setting within the Carpathian region. Its designed capacity of 1,200 m³/day indicates it is sized to accommodate future growth or seasonal variations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) between 2,000 and 10,000 discharging into freshwater. Although the current population served is below 2,000, the plant's capacity suggests it may serve a larger equivalent load or is designed for expansion. The directive mandates secondary treatment for all such discharges to protect water quality. The treated effluent is discharged into local watercourses that ultimately drain into the Olt River basin, a major tributary of the Danube. The Olt River flows south through Romania before joining the Danube, which empties into the Black Sea. The plant's operation helps safeguard the ecological health of these downstream waters, supporting aquatic biodiversity and preventing nutrient pollution in the Danube Delta.

The plant discharges into the Olt River basin, which flows into the Danube and then the Black Sea. This watershed supports diverse aquatic life and is part of a major European ecological corridor. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain water quality in the downstream river system and protect the sensitive Black Sea coastal environment from eutrophication.
