Sewer usage fees are calculated according to the following table.
Note 1: Use Table 1 to calculate one month's usage fee, and Table 2 to calculate two months' usage fee.
Note 2: Normally, the amount is calculated for two months at once, so please use Table 2.
Note 3: Due to the increase in the consumption tax rate and local consumption tax rate that came into effect on October 1, 2019, the consumption tax equivalent included in the sewer usage fee will change from 8% to 10%. A consumption tax equivalent of 10% will be applied from the sewer usage fee calculated for December 2019.
