ROWP Compania de Apa Arad Sector Ineu - Ineu Wastewater Treatment Plant

ROWP Compania de Apa Arad Sector Ineu is a municipal wastewater treatment plant located in Ineu, Arad County, Romania. Serving a population of 2,313, the plant is part of the regional water utility Compania de Apa Arad. It operates with secondary treatment, a standard level for small agglomerations under Romanian and EU regulations. The plant has a designed capacity of 20,000 m³/day and currently discharges 862.43 m³/day of treated wastewater. As a secondary treatment facility, it meets the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 10,000 population equivalent, which mandates secondary treatment for freshwater discharges. The treated effluent is discharged into local watercourses that drain into the Crișul Alb River, a tributary of the Körös River system, which flows into the Tisza River and ultimately the Danube River and Black Sea. The plant plays a key role in protecting the Crișul Alb watershed from untreated sewage pollution.

The plant discharges into the Crișul Alb River basin, part of the larger Tisza-Danube system that drains into the Black Sea. This watershed supports diverse aquatic life and is important for regional agriculture and biodiversity. The secondary treatment reduces organic load and suspended solids, helping to maintain water quality in the downstream rivers and the ecologically sensitive Danube Delta.
