A method and a system for estimating the amount of infiltration of a sewer system are provided to precisely estimate the infiltration for a non-water quality measurement day as well as a water quality measurement day by using various kinds of measurement data of the water quality measurement day. A flow sensor(120) detects a sewer flow in a sewer pipe(110). A water quality sensor(130) detects a sewer quality in the sewer pipe. A CPU(150) calculates the amount of filtration of the sewer pipe based on flow data and water quality data detected from the flow sensor and the water quality sensor. A display device(160) displays the amount of filtration calculated in the CPU. |
