ROWP COMUNA Slimnic Wastewater Treatment Plant, Slimnic, Sibiu County, Romania

ROWP COMUNA Slimnic is a municipal wastewater treatment plant located in Slimnic, a commune in Sibiu County, Romania. The facility serves a population of approximately 2,000 residents, reflecting its role in managing domestic wastewater for this small rural community. The plant is situated inland, away from coastal areas, and operates within the regulatory framework of Romania's environmental protection laws. The plant provides secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. With a designed capacity of 2,400 m³/day and an actual discharge volume of 43.32 m³/day, the facility operates well below its capacity, indicating it is sized to accommodate future growth or seasonal variations. As a Romanian plant, it must comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000, a category that fits this facility. The treated effluent is discharged into local water bodies, likely tributaries of the Cibin River, which flows into the Olt River and eventually reaches the Danube River and the Black Sea. The plant's operation helps protect the local watershed from untreated sewage, supporting aquatic life and downstream water quality in this region of Transylvania.

The plant discharges into the local watershed, which drains into the Cibin River, a tributary of the Olt River. The Olt flows southward into the Danube, which ultimately reaches the Black Sea. This inland location means the effluent influences freshwater ecosystems, including streams and rivers that support diverse aquatic species. The secondary treatment reduces organic pollutants, helping to maintain water quality in the sensitive Carpathian basin environment.
