Totszerdahely Szennyviztisztito Telep - Advanced Wastewater Treatment in Tótszerdahely, Hungary

Totszerdahely Szennyviztisztito Telep is an advanced wastewater treatment facility located in Tótszerdahely, a town in Zala County within the Nyugat-Dunántúl region of Hungary. The plant serves a population of approximately 4,600 residents, reflecting its role in managing municipal wastewater for this small agglomeration. Its design capacity of 5,500 m³/day indicates the infrastructure is sized to accommodate the community's needs. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is particularly important for protecting sensitive receiving waters. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Hungary classifies agglomerations over 10,000 population equivalents as requiring more stringent treatment in sensitive areas. Although this plant serves fewer than 10,000 people, its advanced treatment level suggests it discharges into a sensitive environment or adheres to high local standards. The plant's treated effluent likely discharges into a local watercourse that feeds into the Mura River, a tributary of the Drava, which ultimately flows into the Danube River and the Black Sea. This downstream connection underscores the plant's role in protecting regional water quality and the broader Danube basin ecosystem.

The plant discharges into a local stream that flows into the Mura River, a major tributary of the Drava River. The Drava joins the Danube near Osijek, Croatia, and the Danube carries water to the Black Sea. This watershed supports diverse aquatic life, including fish species such as the Danube salmon and various migratory birds. The advanced treatment level helps minimize nutrient loading, which is critical for preventing eutrophication in downstream water bodies and maintaining ecological balance in the Mura-Drava-Danube corridor.
