To anticipate and prevent potential water shortages, Vitens uses the Resttijden Reservoirs dashboard in ArcGIS Online. The PI System predicts the remaining water supply in terms of hours based on reservoir inflow and outflow, and ArcGIS Online visualizes the predictive data on the map. "A red dot indicates that the water level of the reservoir is low, with less than two hours of supply remaining," said Theo Veltkamp, Analyze and Control (AR&C) analyst, "This can point to a reservoir problem," he continued. "But if the surrounding area changes color as well, the water consumption in that area is higher than predicted. The dashboard then helps us assess whether the reservoir can meet the increase in demand so that we can take action if needed."
The predictive capabilities of the PI System, in combination with the map view in ArcGIS Online, also support Vitens in preparing for extended periods of warm weather. "We are able to compare realtime usage of water with the forecast based on historical data," said Veltkamp. "Historical temperature and consumption in combination with realtime usage produces a map that identifies which areas are at risk for water shortages, allowing us to take direct measures."
