ROWP CL GUGESTI Wastewater Treatment Plant, Gugești, Vrancea, Romania

ROWP CL GUGESTI is a municipal wastewater treatment plant located in Gugești, Vrancea County, Romania. The facility serves a population of approximately 4,080 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. The designed capacity of 6,898 m³/day indicates the plant is sized to accommodate future growth or peak flows, with a current discharge volume of 63.94 m³/day suggesting significant spare capacity. The treated effluent is discharged into local watercourses that drain into the Siret River, a major tributary of the Danube. The Danube ultimately flows into the Black Sea. The plant plays a key role in protecting the Siret River basin from untreated sewage, supporting aquatic life and downstream water quality.

The plant discharges into the Siret River basin, which flows into the Danube River and then the Black Sea. The Siret is an important ecological corridor for fish and migratory birds. Protecting this watershed from nutrient pollution is critical to prevent eutrophication in the Danube Delta and Black Sea coastal zone.
