Külsővat szennyvíztisztító telep - Secondary Wastewater Treatment Plant in Külsővat, Hungary

Külsővat szennyvíztisztító telep is a municipal wastewater treatment plant located in Külsővat, a village in Veszprém County, Hungary. The plant serves a population of 624 and is part of the region's wastewater infrastructure in the Közép-Dunántúl region. The plant provides secondary treatment, which is the standard biological treatment stage required under Hungarian and EU regulations. With a designed capacity of 800 m³/day and an average discharge volume of 73.56 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin. The plant plays a key role in protecting local water quality and supporting the ecological health of the downstream environment, which includes sensitive aquatic habitats.

The plant discharges into small streams that flow into the Marcal River, a tributary of the Rába River, which ultimately joins the Danube. The Danube basin supports diverse aquatic life and is an important ecological corridor in Central Europe. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality.
