Despite the fact that this way of doing maintenance has yet to be fully implemented, it is already yielding results. Preventive maintenance has gained more weight because its importance and successes are emphasized with this way of working. Clustered Maintenance boosts efficiency so downtime of the installations has decreased and the first time right percentage is higher. Previously, at the end of the year Waternet often had a legacy of 10-15% preventive maintenance, that has been reduced to nil.
We also see that first and second priority failures are lower and assets are much more stable; in addition, failures with a third and fourth priority have been drastically reduced. These are expected to decrease further in the longer term as a result of good preventive maintenance. Clustered Maintenance will be the standard at Waternet by the end of 2021.
