Leakage suppression apparatus, leakage suppression system, and leakage suppression program

A leakage suppression apparatus comprising:

• an acquirer that acquires information regarding an amount of water flowing into a water distribution pipeline network having a plurality of nodes and information regarding an amount of water flowing out from the nodes;
• a water amount estimator that estimates the amount of water flowing out at present from the node, based on information regarding the amount of water flowing out from the node acquired in the past by the acquirer;
• a pressure estimator that estimates the water pressure at at least a part of the nodes in the water distribution pipeline network, based on information acquired by the acquirer, the amount of water estimated by the water amount estimator, and model information that includes connection information of the nodes in the water distribution pipeline network;
• an extractor that extracts a minimum water pressure value from a plurality of water pressures that include the water pressure estimated by the pressure estimator;
• and
• a controller that controls an adjustor to adjust at least one of a water pressure and a flow rate of water flowing into the water distribution pipeline network, based on the minimum water pressure value extracted by the extractor.
