Dejtar Szennyviztisztito Telep - Advanced Wastewater Treatment in Ipolyvece, Hungary

Dejtar Szennyviztisztito Telep is an advanced wastewater treatment plant located in Ipolyvece, in the Észak-Magyarország region of Hungary. The plant serves a population of approximately 3,402 people, 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 sensitive areas. With a designed capacity of 2,000 m³/day and an actual discharge volume of 401.03 m³/day, the plant operates well within its capacity. The treated effluent is discharged into local waterways that ultimately drain into the Danube River basin, contributing to the protection of the Black Sea ecosystem. The advanced treatment ensures high-quality effluent, reducing nutrient loads and supporting downstream aquatic life.

The plant discharges into the Ipoly River, a tributary of the Danube, which flows into the Black Sea. The Ipoly River supports diverse aquatic life and is an important migratory corridor for fish species. Advanced treatment helps minimize nutrient pollution, protecting the river's ecological health and the downstream Danube delta.
