Szecseny Szennyviztisztito Telep - Municipal Wastewater Treatment Plant in Szécsény, Hungary

Szecseny Szennyviztisztito Telep is a municipal wastewater treatment plant located in Szécsény, a town in Nógrád county, northern Hungary. The facility serves a population of approximately 12,990 people, placing it in the medium agglomeration category under EU classification. As a Hungarian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Hungary has transposed these requirements into national law, and plants of this scale are typically subject to regular monitoring and permitting by the competent water authority. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Tisza River basin, which flows southward into Serbia and eventually reaches the Danube River. The Tisza basin supports diverse aquatic ecosystems and is an important migratory corridor for fish species. Proper treatment helps protect water quality in this ecologically significant river system.

The plant discharges into local streams that are part of the Tisza River basin, which flows through Hungary and into Serbia before joining the Danube. The Tisza River supports diverse aquatic life and is an important ecological corridor. Downstream areas include floodplain forests and wetlands that rely on good water quality for their ecological function. Effective wastewater treatment helps prevent nutrient enrichment and maintains the health of these downstream ecosystems.
