Erd Szennyviztisztito Telep - Tököl Wastewater Treatment Plant, Hungary

Erd Szennyviztisztito Telep is a municipal wastewater treatment plant located in Tököl, within the Pest vármegye of Hungary's Közép-Magyarország region. The facility serves a population of approximately 72,404, placing it in the medium-to-large agglomeration category under Hungarian and EU regulations. As a plant of this scale in Hungary, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For agglomerations above 10,000 population equivalent, the directive mandates compliance with specific effluent standards. The regulatory framework ensures appropriate treatment for the population served. The plant discharges treated wastewater into local water bodies that ultimately drain into the Danube River basin. The Danube flows through Hungary and into the Black Sea, making the plant's operations significant for downstream water quality. The surrounding area includes agricultural and urban zones, and the plant plays a key role in protecting local streams and the broader Danube ecosystem.

The plant's treated effluent enters local waterways that feed into the Danube River, which flows through Hungary and into the Black Sea. The Danube basin supports diverse aquatic life and is an important migratory corridor for fish species. The plant's location inland, away from coastal areas, reduces direct marine impact, but its discharge affects the ecological health of the river system and downstream wetlands.
