ROWP AQUANOVA HARGHITA Sector Praid Wastewater Treatment Plant, Praid, Romania

ROWP AQUANOVA HARGHITA Sector Praid is a municipal wastewater treatment plant located in Praid, Harghita County, Romania. The facility serves a population of approximately 3,823 residents and is designed to handle a capacity of 4,200 cubic meters per day, with an average discharge volume of 83.18 m³/day. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids before discharge. The treated effluent is discharged into local watercourses that drain into the Târnava Mică River, a tributary of the Mureș River, which ultimately flows into the Tisza River and the Danube River basin. The plant plays a key role in protecting the water quality of these rivers and the surrounding environment in the Carpathian region.

The plant discharges into the Târnava Mică River basin, which flows into the Mureș River, a major tributary of the Tisza River and part of the Danube River system. The receiving waters support diverse aquatic life and are important for regional biodiversity. The area is located in the Eastern Carpathians, where maintaining water quality is critical for downstream ecosystems and human use.
