ROWP SPAC Vanju Mare - Advanced Wastewater Treatment in Vânju Mare, Romania

ROWP SPAC Vanju Mare is a wastewater treatment facility located in Vânju Mare, a town in Mehedinți County, Romania. The plant serves a population of approximately 417 residents and has a designed capacity of 4,000 cubic meters per day, indicating it is sized to accommodate future growth or seasonal variations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Romania requires appropriate treatment for discharges into sensitive areas, and advanced treatment is typical for plants serving agglomerations of this scale in such contexts. The treated effluent is discharged into the local watershed, which ultimately drains into the Danube River basin. The Danube is a major European waterway that flows into the Black Sea, supporting diverse aquatic ecosystems and providing water for agriculture and industry. The plant's advanced treatment helps protect downstream water quality and ecological health.

The plant discharges into the Danube River basin, which flows through Romania and several other countries before reaching the Black Sea. The Danube supports a rich diversity of fish and bird species, including migratory populations. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in the Black Sea, a region sensitive to nitrogen and phosphorus pollution.
