Situation
With an age of nearly 50 years, the raw water pipeline near and in a petrochemical plant was close to the end of its life span due to successive leakages in recent years. Since some of the leaks were at the beginning and under an intersection of a railway platform, actions needed to be taken.
Short-term tasks were based on the scheduled supply cuts.
This could be achieved by installing long sections depending on existing elements.
The section to be rehabilitated consists of an asbestos cement pipe with a length of 2.4 kilometres and a reinforced concrete with sheet metal jacket and asbestos cement with another 3.6 kilometres.
