ROWP Gospodarie Comunala Baile Tusnad - Wastewater Treatment Plant in Tușnad, Romania

ROWP Gospodarie Comunala Baile Tusnad is a municipal wastewater treatment plant located in Tușnad, Harghita County, Romania. The facility serves a population of approximately 1,313 residents, making it a small-scale treatment operation within the region. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 2,400 cubic meters per day, with an average discharge volume of 447.86 cubic meters per day, indicating operational capacity well within design limits. The treated effluent is discharged into the local water system, which ultimately drains into the Olt River basin. The Olt River flows southward through Romania, eventually reaching the Danube River and the Black Sea. The plant plays a key role in protecting the water quality of the Olt River and its downstream ecosystems.

The plant discharges into the Olt River basin, a major tributary of the Danube River. The Olt River supports diverse aquatic life and provides water for agricultural and industrial use in the region. Downstream, the Danube Delta is a critical ecological zone for migratory birds and fish species. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, contributing to the health of these downstream environments.
