摘要

The detection system 1 includes a water usage acquisition unit 11, a water usage calculation unit 12, an implementation frequency calculation unit 13, a usage content determination unit 14, and a correspondence generation unit 15. The acquisition unit 11 obtains water usage from a water meter. Based on the water usage, the calculation unit 12 obtains the standard deviation of the water usage time, the number of times of water usage, the water usage, and the water usage per unit time for each implementation. The calculation unit 13 obtains a relationship (first relationship) between the water usage time and the usage frequency based on the water usage time obtained by the calculation unit 12. The determination unit 14 determines the use content based on the number of times of water use and the standard deviation for the use in which the execution frequency satisfies the predetermined condition in the first relationship. The production | generation part 15 matches the content of a use, water usage, and water usage time for every content of a use.
