Opusztaszer Szennyviztisztito Telep - Wastewater Treatment Plant in Ópusztaszer, Hungary

Opusztaszer Szennyviztisztito Telep is a municipal wastewater treatment plant located in Ópusztaszer, a village in the Kistelek district of Csongrád-Csanád county, Hungary. The plant serves a population of approximately 770 residents and operates with secondary treatment, which is the standard biological treatment required for small agglomerations under Hungarian and EU regulations. The plant has a designed capacity of 3,333 cubic meters per day and currently discharges an average daily volume of about 91 cubic meters, indicating it operates well below its design capacity. As a facility in the Dél-Alföld region, it falls under Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for settlements with a population equivalent above 2,000. For smaller communities like Ópusztaszer, appropriate treatment is required to protect local water quality. The treated effluent is discharged 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 ecological corridor in the Carpathian Basin. The plant's operation helps protect downstream water quality in this sensitive river system.

The plant discharges into local streams that flow into the Tisza River, which is the second-largest river in Hungary and a key tributary of the Danube. The Tisza basin supports a rich diversity of fish and bird species, including several that are protected under EU law. The region's flat terrain and agricultural land use make proper wastewater treatment essential to prevent nutrient pollution and maintain the ecological health of the Tisza River system.
