Securing long-term water management at the Kvassay Dam and Pumping Station

AVK delivers large-diameter valve solutions to the rehabilitation of key water management infrastructure on the Danube – Europe's second longest river – in Budapest, Hungary.

The Kvassay Dam and Pumping Station, located in Budapest, Hungary, is undergoing a major rehabilitation to safeguard its continued role in regional water regulation. Often referred to as “The Lord of the Danube,” the more than 100-year-old complex plays a central part in flood protection, water level management and ecological stability in the Ráckevei (Soroksári)-Danube branch (RSD).

The extensive upgrade, co-financed by the Hungarian State and the Cohesion Fund under the Environmental and Energy Efficiency Operational Program, was launched in response to record low water levels in the Danube, including a historic minimum of just 33 cm in 2018. These conditions exposed limitations in the existing infrastructure and underlined the need for long-term, resilient solutions.

Ensuring water flow under all conditions

The new pumping station is designed to maintain water supply to the RSD even when the Danube’s natural flow cannot sustain it. The new setup can deliver at least 30 m³/s of water, even at record-low water levels of just 17 cm.

This is essential not only for maintaining water levels, but also for biodiversity, agricultural irrigation, fishponds and proper dilution of treated wastewater discharged from the South Pest wastewater treatment plant.

AVK products supporting long-term reliability in critical infrastructure

The rehabilitation of the Kvassay Dam and Pumping Station ensures that it is ready for future challenges such as climate changes. With its expanded capabilities, the facility will continue to contribute to water management, flood defence and energy supply to Budapest and surrounding areas.

AVK Magyarország has delivered large-diameter valve solutions for the rehabilitation project designed for long-term reliability under demanding operating conditions.
