ROWP RASP Ploiesti Wastewater Treatment Plant, Corlătești, Romania

ROWP RASP Ploiesti is a major wastewater treatment facility located in Corlătești, a locality within Berceni commune, Prahova County, Romania. The plant serves a population of over 208,000, classifying it as a large agglomeration under EU regulations. Its location in the Prahova Valley places it within a region known for oil and industrial activity, which influences the wastewater composition. As a plant serving more than 150,000 people, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment as a minimum. For sensitive areas, tertiary treatment may be mandated. The plant's treatment process and capacity details are not publicly available, but the regulatory framework ensures compliance with discharge standards. The treated effluent is discharged into the local water network, ultimately flowing into the Prahova River, a tributary of the Ialomița River, which joins the Danube. The Danube then flows into the Black Sea. This downstream chain connects the plant to the Danube Delta Biosphere Reserve, a critical ecological zone supporting diverse aquatic life and migratory birds.

The plant discharges into the Prahova River basin, which flows into the Ialomița River, a tributary of the Danube. The Danube carries the effluent to the Black Sea, passing through the Danube Delta, a vast wetland of ecological importance. The delta supports diverse aquatic life, including fish species and migratory birds, and is sensitive to nutrient pollution. Effective treatment at ROWP RASP Ploiesti is crucial to prevent eutrophication and protect downstream ecosystems.
