ROWP ION NECULCE Buznea Wastewater Treatment Plant, Războieni, Iași County

ROWP ION NECULCE Buznea is a municipal wastewater treatment plant located in Războieni, a locality within Ion Neculce commune, Iași County, Romania. The plant serves a small population of 266 residents and is designed to handle a capacity of 2200 cubic meters per day, reflecting the needs of a rural agglomeration. As a secondary treatment facility, the plant provides biological treatment to remove organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), secondary treatment is the minimum standard for discharges into freshwater bodies, ensuring compliance with Romanian environmental regulations. The treated effluent is discharged into local watercourses that drain into the Bahlui River, a tributary of the Jijia River, which ultimately flows into the Prut River and then the Danube River. The plant plays a key role in protecting the Bahlui River basin from nutrient pollution and supporting downstream aquatic ecosystems.

The plant discharges into the Bahlui River basin, part of the Prut-Danube catchment. The Bahlui River supports diverse aquatic life and is used for irrigation and fishing. Downstream, the Prut River forms part of the border with Moldova and flows into the Danube Delta, a ecologically sensitive area. The plant's secondary treatment helps reduce organic load and nutrient inputs, mitigating eutrophication risks in the lower reaches.
