In the event of heavy rainfall, risky situations are increasingly being created because tunnels and roads are flooded. If this occurs in several places at the same time, the safety of a city is endangered, because in addition to normal traffic, the police, ambulances and fire trucks are hindered. With real-time control from TeleControlNet, regional pumps are controlled in advance and from a central control algorithm in the event of a threat of flooding, which drastically reduces the risk of flooding.
