ROWP Primaria Balotesti Wastewater Treatment Plant, Dumbrăveni, Romania

ROWP Primaria Balotesti is a municipal wastewater treatment plant located in Balotești, Ilfov County, Romania, serving the locality of Dumbrăveni. The plant provides secondary treatment for a population equivalent of 3,220, with a designed capacity of 4,000 cubic meters per day and an average discharge volume of 716.29 cubic meters per day. As a secondary treatment facility, the plant meets the minimum requirements under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations between 2,000 and 10,000 population equivalent. The directive mandates secondary treatment for all discharges from such agglomerations, ensuring organic matter and suspended solids are reduced to acceptable levels before discharge. The plant discharges treated effluent into local watercourses that ultimately drain into the Argeș River basin, which flows southward to the Danube River and then into the Black Sea. The surrounding area is part of the Romanian Plain, a region with intensive agriculture and several protected areas that rely on good water quality.

The treated effluent from ROWP Primaria Balotesti enters the local drainage network, which feeds into the Argeș River, a major tributary of the Danube. The Danube then flows into the Black Sea, a semi-enclosed sea with sensitive ecosystems. The Argeș River basin supports diverse aquatic life and is important for irrigation and drinking water supply. The plant's secondary treatment helps reduce nutrient loads, which is critical for preventing eutrophication in downstream water bodies.
