Hungarian gas company KEG Gaz, 80 km north of Budapest, has a major underground gas reservoir and its operations were threatened by the flood water from the Danube River. Local authorities in Dunaalmas summoned the NoFloods mobile water filled flood barrier to save the gas plant. 6 hours after arrival the NoFloods Mobile Barrier fully deployed by a team of 3 people surrounding the plant completely. The NoFloods Barrier Twin Tube 125 has a recommended maximum flood water height of 800mm. The water rose to 910mm but the flood barrier held back the rising flood water. The barrier remained deployed from June 6 to June 12. The total length was 400 metres. Flood water was used to fill the tubes with water.
