ROWP CL CORUND Wastewater Treatment Plant, Corund, Harghita, Romania

ROWP CL CORUND is a wastewater treatment plant located in Corund, Harghita County, Romania. It serves a population of 3,218 and has a designed capacity of 3,500 m³/day, with a discharge volume of 260.38 m³/day. The plant provides secondary treatment, which is the standard level for small agglomerations under Romanian and EU regulations. As a secondary treatment facility, ROWP CL CORUND meets the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000. The plant's capacity utilization is low, indicating it operates well within its design limits. The plant discharges treated wastewater into a local watercourse that eventually drains into the Târnava Mare River, a tributary of the Mureș River, which flows into the Tisza River and ultimately the Danube River and the Black Sea. The surrounding area is part of the Carpathian region, known for its diverse aquatic ecosystems and biodiversity.

The treated effluent from ROWP CL CORUND likely enters a small stream that feeds into the Târnava Mare River, a major tributary of the Mureș River. The Mureș flows into the Tisza River, which joins the Danube before reaching the Black Sea. This watershed supports diverse aquatic life and is important for regional water quality. The plant's secondary treatment helps reduce organic pollutants and protect downstream ecosystems.
