ISSEANE is a waste treatment site located in Issy-les-Moulineaux, owned by SYCTOM and constructed in 2008. It includes a sorting center as well as an energy recovery plant. ISSEANE has its own firewater system, with firewater coming from a storage tank supplied by the Seine river via underground water pipes.
The facilities are subject to several malfunctions:
– Overpressure when the water pumps start, which causes the safety valves to open
– A drop in water pressure when the pumps stop, causing the rubber membrane of the accumulator tank to rip
– Heavy cavitation occurring in control valves, degrading the piping network and creating high levels of noise and vibration
