ROWP Compania de Apa Arad Sector Gurahont - Primary Wastewater Treatment Plant in Iosaș, Romania

ROWP Compania de Apa Arad Sector Gurahont is a wastewater treatment plant located in Iosaș, a village in Gurahonț commune, Arad County, Romania. The plant serves a small population of 750 people, reflecting its role in a rural community. Its designed capacity is 1500 m³/day, with a current discharge volume of 78.60 m³/day. The plant provides primary treatment, which involves physical processes like sedimentation to remove solids. As a small agglomeration in Romania, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into freshwater. For plants serving fewer than 2000 population equivalents, the directive mandates 'appropriate treatment' rather than secondary treatment, which aligns with the primary level reported. The treated effluent is discharged into the local watershed, which ultimately drains into the Crișul Alb River and then into the Körös River system, eventually reaching the Tisza River and the Danube. This water body supports diverse aquatic life and is part of the larger Danube Basin, a region of ecological importance. The plant's operation helps protect local water quality in this rural area.

The plant discharges into the Crișul Alb River basin, which flows into the Körös River system and ultimately the Tisza and Danube Rivers. This watershed supports diverse aquatic ecosystems, including fish and macroinvertebrate communities. The area is part of the larger Danube Basin, which is ecologically sensitive and subject to EU water quality standards.
