Puspokmolnari Szennyviztisztito telep - Advanced Wastewater Treatment in Püspökmolnári, Hungary

Puspokmolnari Szennyviztisztito telep is a municipal wastewater treatment facility located in Püspökmolnári, a village in Vas County within the Nyugat-Dunántúl region of Hungary. The plant serves a population of 763, classifying it as a small agglomeration under Hungarian and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 991 m³/day and a current discharge volume of 89.94 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into local waterways that ultimately drain into the Rába River, a tributary of the Danube. The Danube then flows into the Black Sea, making the plant part of a large international river basin. Advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the Danube Basin.

The plant discharges into the Rába River catchment, which flows into the Danube and eventually the Black Sea. The Rába River supports diverse aquatic life and is an important ecological corridor in western Hungary. Advanced treatment at this facility reduces nutrient and pollutant loads, helping to maintain water quality in the Danube Basin, a region of significant ecological and economic importance.
