The vault walls along the canals are inspected monthly. “These measurements show that there is no movement in the walls,” the municipality said. In places where the municipality knows that the foundations are in poor condition, periodic inspections are also carried out with divers. “A recent inspection with divers at one of these locations showed that the current bags are no longer functioning properly.” The temporary clay bags are also in need of replacement in other places.
