ROWP Primaria Ionesti Gura Susitei - Advanced Wastewater Treatment in Picu, Romania

ROWP Primaria Ionesti Gura Susitei is a wastewater treatment plant located in the village of Picu, within Ionești commune, Gorj County, Romania. The facility serves a small population of 105 residents and is designed with a capacity of 1,500 cubic meters per day, indicating it is sized to accommodate future growth or seasonal variations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for small agglomerations. This level of treatment ensures high-quality effluent suitable for discharge into sensitive environments. The plant's current discharge volume is 61.70 m³/day, reflecting its operation well below capacity. The treated effluent is likely discharged into a local watercourse within the Jiu River basin, which flows southward to join the Danube River and eventually the Black Sea. The advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's waterways.

The plant is situated inland in the Gorj County region, part of the Jiu River catchment. The Jiu River flows into the Danube, which empties into the Black Sea. The advanced treatment level helps safeguard the local watershed, which supports diverse aquatic life and is important for regional biodiversity. The facility's location away from the coast reduces direct marine impact, but its effluent contributes to the overall water quality of the Danube basin.
