ROWP Pojejena Wastewater Treatment Plant, Pojejena, Caraș-Severin, Romania

ROWP Pojejena is a municipal wastewater treatment plant located in Pojejena, Caraș-Severin County, Romania. It serves a small population of 550 residents, reflecting its role in a rural community along the Danube corridor. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) between 2,000 and 10,000. Although the plant's population served is below this threshold, secondary treatment ensures effective removal of organic matter and suspended solids before discharge. The treated effluent is discharged into the local environment, likely flowing into the Danube River via nearby tributaries. The Danube is a major European waterway that ultimately reaches the Black Sea. The plant's operation helps protect downstream water quality and aquatic ecosystems in the Danube basin.

The plant discharges into the Danube River basin, which flows through several countries before reaching the Black Sea. The Danube supports diverse aquatic life and is an important migratory corridor for fish and birds. The secondary treatment reduces organic pollution, helping to maintain the ecological health of the river and its delta.
