ROWP SC GO SA GHEORGHENI Wastewater Treatment Plant, Ciumani, Harghita, Romania

ROWP SC GO SA GHEORGHENI is a municipal wastewater treatment plant located in Ciumani, Harghita County, Romania. The plant serves a population of approximately 11,811, placing it in the medium agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). As a Romanian facility, it operates within the national regulatory framework aligned with EU environmental standards. Under the EU UWWTD, agglomerations with a population equivalent (PE) between 2,000 and 10,000 require appropriate treatment, while those above 10,000 PE generally require secondary treatment. Given its population served of 11,811, the plant is expected to provide at least secondary treatment to meet compliance standards. The regulatory context ensures that appropriate treatment levels are mandated. The plant discharges treated wastewater into local water bodies within the Harghita region, which is part of the larger Tisza River basin. The Tisza River flows through Hungary and Serbia before joining the Danube, ultimately reaching the Black Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from untreated sewage pollution.

The plant discharges into local streams that feed into the Mureș River, a major tributary of the Tisza River. The Tisza River basin supports diverse aquatic life and is an important ecological corridor in Central Europe. The treated effluent ultimately reaches the Black Sea via the Danube River. The plant's location in the Carpathian region means it helps protect sensitive mountain streams and downstream habitats from nutrient pollution and pathogens.
