Abstract: A buried piping probability-of-water-leakage-accidents prediction apparatus includes: an exceedance-probability-of-pipe-wall-thickness calculation unit; and a probability-of-water-leakage-accidents calculation unit. The exceedance-probability-of-pipe-wall-thickness calculation unit calculates an exceedance probability of pipe wall thickness of buried piping by inputting a burial environment, a burial period of time and a pipe wall thickness of the buried piping to an exceedance-probability-of-pipe-wall-thickness prediction model. The probability-of-water-leakage-accidents calculation unit calculates a probability of water leakage accidents of the buried piping using the exceedance probability of pipe wall thickness and a conversion coefficient.
