ROWP Primaria Ionesti Ionesti - Advanced Wastewater Treatment in Ionești, Gorj County

ROWP Primaria Ionesti Ionesti is a municipal wastewater treatment facility located in Ionești, a commune in Gorj County, Romania. The plant serves a population of 381 residents and is designed with a capacity of 1,500 cubic meters per day, currently discharging approximately 95 cubic meters per day of treated wastewater. The plant employs advanced treatment processes, ensuring high-quality effluent that meets Romanian and EU environmental standards. As a facility in an EU member state, it operates under the Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. For small agglomerations like Ionești, advanced treatment provides robust protection for local water bodies. The treated effluent is discharged into the local watershed, which ultimately drains into the Jiu River, a major tributary of the Danube. The Danube then flows into the Black Sea, making the plant's performance important for downstream ecosystems. The advanced treatment helps reduce nutrient loads and protect aquatic life in the receiving waters.

The plant discharges into the Jiu River basin, which flows southward to join the Danube and eventually the Black Sea. The Jiu River supports diverse aquatic life and is used for irrigation and recreation. Advanced treatment at this plant helps minimize nutrient pollution, safeguarding water quality in the downstream Danube Delta ecosystem, an ecologically sensitive area.
