ROWP SC COMPANIA DE APA ARAD pl Pecica is a municipal wastewater treatment plant located in Pecica, Arad County, Romania. The facility serves a small agglomeration of around 1,042 people, reflecting the scale of rural wastewater infrastructure in western Romania. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) between 2,000 and 10,000. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 1,000 m³/day and discharges an average volume of 679.86 m³/day. The treated effluent is discharged into the local water system, which ultimately drains into the Mureș River, a major tributary of the Tisza River. The Tisza flows into the Danube, which reaches the Black Sea. The plant plays a key role in protecting the Mureș River basin from untreated wastewater, supporting aquatic life and downstream water quality.

The plant discharges into the Mureș River basin, which flows into the Tisza River and then the Danube before reaching the Black Sea. This watershed supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The secondary treatment provided helps reduce nutrient and organic pollution, mitigating eutrophication risks in downstream water bodies.
