As a supplier of drinking water, we unfortunately have to deal with leaks in our daily operations. In most cases, we are alerted by our customers. Usually because the pressure is too low, or they are not receiving any water at all. This means that we are always one step behind. We wanted to be able to be one step ahead instead. Our challenge was to create business rules in OSIsoft PI that would alert us whenever an exception occurs in our distribution network. Our Central Water Distribution department can then immediately take action, even before we receive the first call from our customers. We have developed these business rules in a combined effort between business and IT. In our presentation, we will talk about how this functionality was developed, which parts of the PI system we use, the current operational results (hit rate) and lessons learned."
