It serves a small population of 12 people, reflecting the rural character of the area. The plant is part of the municipal infrastructure managed by the local water utility. 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. The designed capacity is 200 m³/day, with an actual discharge volume of 9.96 m³/day, indicating low utilization. The plant operates under Romania's national water legislation, which transposes EU directives. The treated effluent is discharged into local watercourses that drain into the Strei River, a tributary of the Mureș River, which flows into the Tisza River and ultimately the Danube River and the Black Sea. The plant plays a role in protecting the water quality of these downstream ecosystems.

The plant discharges into the Strei River basin, part of the larger Mureș-Tisza-Danube system that flows into the Black Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality in a region with agricultural and rural land use.
