Crucial junction renewal completed overnight

In Northern Hungary, a crucial DN600 junction supplying potable water to twelve municipalities required urgent renovation. The installation, consisting of more than 50-year-old cast-iron pipes and valves,
had reached the end of its service life and posed an increasing risk of failure. Because of its strategic importance, the reconstruction window was extremely limited: the system had to be replaced overnight and
returned to full operation before morning. Speed, reliability and absolute installation safety were therefore essential for the project’s success.
