Balatonlelle Szennyviztisztito Telep - Karád Wastewater Treatment Plant, Hungary

Balatonlelle Szennyviztisztito Telep is a wastewater treatment plant located in Karád, within the Dél-Dunántúl region of Hungary. It serves a population of approximately 40,563, classifying it as a large agglomeration under EU standards. The plant is situated inland, away from coastal areas, and its operations are integral to the local water management infrastructure. As a facility serving over 40,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum, with tertiary treatment in sensitive areas. The regulatory framework ensures compliance with discharge standards. The plant discharges into the local watershed, which ultimately drains into Lake Balaton, a large freshwater lake and significant ecological and recreational resource. Protecting Lake Balaton from nutrient pollution is critical, as it supports diverse aquatic life and tourism. The plant's operations help maintain water quality in the region.

The plant's treated effluent flows into the local drainage network, which feeds into Lake Balaton, the largest lake in Central Europe. Lake Balaton is a shallow, nutrient-sensitive water body that supports diverse aquatic ecosystems and is a major tourist destination. Protecting it from eutrophication requires effective nutrient removal, making the plant's treatment performance vital for the lake's ecological health and downstream water quality.
