Egyhazashetye Szennyviztisztito Telep - Advanced Wastewater Treatment in Vas County, Hungary

Egyhazashetye Szennyviztisztito Telep is an advanced wastewater treatment facility located in the village of Egyházashetye, in Vas County, western Hungary. The plant serves a population of approximately 2,080 residents, reflecting its role in managing domestic wastewater for this small agglomeration in the Nyugat-Dunántúl region. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is particularly important for protecting sensitive receiving waters. Hungary, as an EU member state, implements the Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for agglomerations over 10,000 population equivalent discharging into sensitive areas. Although this plant serves a smaller population, its advanced treatment level indicates a commitment to high effluent quality. The treated wastewater is discharged into local watercourses that eventually drain into the Danube River basin and ultimately the Black Sea. The plant's location in a rural, inland area means its discharge supports local streams and groundwater, contributing to the ecological health of the region's aquatic habitats. The advanced treatment helps minimize nutrient loading, protecting downstream water quality and biodiversity.

The plant discharges into local streams that are part of the Rába River catchment, a tributary of the Danube. The Danube flows into the Black Sea, making this plant part of a vast transboundary basin. The region's aquatic ecosystems support diverse fish and invertebrate communities, and advanced treatment helps prevent eutrophication in downstream waters.
