Demecser Szennyviztisztito Telep - Gégény Wastewater Treatment Plant, Hungary

Demecser Szennyviztisztito Telep is a municipal wastewater treatment plant located in Gégény, within the Kemecsei district of Szabolcs-Szatmár-Bereg county, Hungary. The plant serves a population of approximately 11,081 people in the Észak-Alföld region, an area characterized by flat plains and agricultural activity. As a plant serving a medium-sized agglomeration, it operates under Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for agglomerations of this scale, with more stringent tertiary treatment if the receiving waters are designated as sensitive areas. Regulatory compliance ensures appropriate treatment standards. The plant discharges treated effluent into local watercourses that ultimately drain into the Tisza River basin, a major tributary of the Danube. The Tisza River supports diverse aquatic ecosystems and is an important water resource for the region. Proper wastewater treatment is essential to protect water quality in this sensitive river system.

The plant's treated effluent flows into local streams that are part of the Tisza River basin. The Tisza River is a major tributary of the Danube, ultimately reaching the Black Sea. The watershed supports diverse aquatic life and is ecologically sensitive, requiring effective nutrient removal to prevent eutrophication and maintain water quality.
