Algyo Szennyviztisztito Telep - Secondary Wastewater Treatment in Algyő, Hungary

Algyo Szennyviztisztito Telep is a municipal wastewater treatment facility located in Algyő, a village in the Dél-Alföld region of southern Hungary. The plant serves a population of approximately 4,800 residents, classifying it as a small agglomeration under Hungarian and EU regulations. Its location in the Great Plain (Alföld) region places it in a predominantly agricultural and rural setting. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater. With a designed capacity of 12,000 m³/day, the facility has reserve capacity for future growth. The actual discharge volume is about 566 m³/day, indicating that current operations are well within design limits. The treated effluent is discharged into local drainage channels that ultimately flow into the Tisza River, a major tributary of the Danube. The Tisza basin supports diverse aquatic life and is an important ecological corridor in Central Europe. By providing secondary treatment, the plant helps reduce organic pollution and nutrient loads, protecting downstream water quality in the Tisza and Danube rivers.

The plant's treated effluent enters local watercourses that drain into the Tisza River, which flows through Hungary and into Serbia before joining the Danube. The Tisza basin is ecologically significant, supporting fish species such as catfish and pike, and providing habitat for migratory birds. The region's flat terrain and agricultural land use mean that nutrient runoff is a concern; secondary treatment helps mitigate eutrophication risks in downstream lakes and the Danube Delta.
