Nemesszalok Szennyviztisztito Telep - Advanced Wastewater Treatment in Nemesszalók, Hungary

Nemesszalok Szennyviztisztito Telep is a municipal wastewater treatment facility located in Nemesszalók, a village in Veszprém County, Hungary. The plant serves a population of approximately 2,300 residents, 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 1,660 m³/day and an average daily discharge of 271.13 m³, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, a major European watershed. The advanced treatment level ensures high-quality effluent, protecting downstream aquatic ecosystems and supporting the ecological health of the region's surface waters.

The plant discharges into local streams that flow into the Marcal River, a tributary of the Rába River, which eventually joins the Danube. This watershed supports diverse aquatic life and is part of the larger Danube basin, which drains into the Black Sea. The advanced treatment helps minimize nutrient loading and protects sensitive downstream habitats.
