ROWP CL AL COMUNEI GHELARI SPAAC - Primary Wastewater Treatment Plant in Dealu Mic, Hunedoara County

ROWP CL AL COMUNEI GHELARI SPAAC is a wastewater treatment plant located in Dealu Mic, a village in Hunedoara County, Romania. The plant serves a population of 690 and has a designed capacity of 2,500 m³/day, with an average discharge volume of 38.12 m³/day. It operates under Romania's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for small agglomerations. The plant provides primary treatment, which involves physical sedimentation to remove settleable solids. For a small agglomeration of this size, primary treatment may be considered adequate under certain conditions, though secondary treatment is generally recommended for sensitive areas. The plant's capacity utilization is low, suggesting it is designed for future growth or seasonal peaks. The treated effluent is discharged into a local watercourse that eventually flows into the Mureș River, a major tributary of the Tisza River, which drains into the Danube River and ultimately the Black Sea. The surrounding area is characterized by hilly terrain and forests, with the plant located near the Poiana Ruscă Mountains. The local watershed supports diverse aquatic life and is important for regional biodiversity.

The plant discharges into a small stream that feeds into the Mureș River, which flows through western Romania into Hungary, joining the Tisza River. The Tisza then flows into the Danube, reaching the Black Sea. The Mureș River basin supports diverse aquatic ecosystems, including fish species such as barbel and chub. The area is ecologically sensitive due to its proximity to the Poiana Ruscă Mountains, which host protected habitats for flora and fauna.
