ROWP Galautas Wastewater Treatment Plant, Toleșeni, Harghita, Romania

ROWP Galautas is a municipal wastewater treatment plant located in Toleșeni, a locality within Gălăuțaș commune, Harghita County, Romania. The plant serves a population of approximately 2,403 residents, classifying it as a small agglomeration under Romanian and EU regulations. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Its designed capacity is 5,000 m³/day, with a current discharge volume of 74.73 m³/day, indicating significant reserve capacity. The plant operates under Romania's national water management framework, which transposes EU directives into local law. The treated effluent is discharged into a local watercourse that eventually flows into the Mureș River, a major tributary of the Tisza River, which drains into the Danube and ultimately the Black Sea. The plant plays a key role in protecting the local watershed from untreated sewage, supporting aquatic life and downstream water quality.

The plant discharges into a small watercourse within the Mureș River basin, which flows into the Tisza River, a major tributary of the Danube. The Danube then empties into the Black Sea. The Mureș River supports diverse aquatic ecosystems and is an important migratory corridor for fish species. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain the ecological health of the receiving waters.
