Chlopice Wastewater Treatment Plant, Boratyn, Poland

The Chlopice wastewater treatment plant is located in Boratyn, within the gmina Chłopice in powiat jarosławski, województwo podkarpackie, Poland. It serves a population of 2,765, classifying it as a small agglomeration under Polish and EU regulations. The plant is situated near the A4 motorway, in a rural area of southeastern Poland. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity is 3,300 m³/day, and the current discharge volume is 394.25 m³/day, indicating significant spare capacity. It operates under Polish national regulations implementing EU directives. The treated effluent is discharged into local watercourses that eventually drain into the San River, a tributary of the Vistula River, which flows into the Baltic Sea. The plant plays a key role in protecting the local watershed from untreated wastewater, supporting water quality in the San River basin and the broader Vistula catchment.

The plant discharges into local streams that feed the San River, a major tributary of the Vistula River. The Vistula drains into the Baltic Sea, making the plant part of a large international watershed. The San River supports diverse aquatic life and is an important ecological corridor in the Carpathian region. Secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream ecosystems from eutrophication.
