Tac Szennyviztisztito Telep - Secondary Wastewater Treatment in Tác, Hungary

Tac Szennyviztisztito Telep is a municipal wastewater treatment facility located in Tác, a village in Fejér County, central Hungary. The plant serves a population of around 1,570 and operates with a designed capacity of 1,665 m³/day, treating an annual volume of 185.07 thousand m³. It is situated in the Közép-Dunántúl region, an area characterized by agricultural and small-scale industrial activity. The plant provides secondary treatment, which is the standard biological treatment level required under Hungarian and EU regulations for agglomerations of this size. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), settlements with a population equivalent (PE) between 2,000 and 10,000 are generally required to have secondary treatment, and Tác's plant meets this standard. The facility is likely operated by a local water utility or municipal authority, ensuring compliance with national discharge standards. Treated effluent from the plant is discharged into local watercourses that eventually drain into the Danube River basin, a major European waterway flowing into the Black Sea. The plant plays a key role in protecting the region's surface waters from nutrient pollution and organic load, supporting aquatic life and downstream water quality in the Danube catchment.

The plant discharges into the Danube River basin, which flows through Hungary and several other countries before reaching the Black Sea. The local watershed includes small streams and agricultural drainage channels that feed into larger rivers like the Sárvíz or Sió, ultimately joining the Danube. This region supports diverse aquatic habitats and is important for migratory fish species. Effective wastewater treatment helps prevent eutrophication and maintains the ecological balance of these water bodies.
