Room (1—4, each) ..... | 8.030

Each additional bath facility ..... | 10.950
First water closet ..... | 21.000
Each additional water closet ..... | 14.600
Each water-using device ..... | 5.475
(5) For users whose sewage is measured by a meter or method approved by the manager of transportation and infrastructure, the charge shall be computed by multiplying the volume of sewage during the billing period by $3.97/thousand gallons effective July 1, 2016; $4.17/thousand gallons effective January 1, 2017; $4.34/thousand gallons effective January 1, 2018; $4.51/thousand gallons effective January 1, 2019; $4.69/thousand gallons effective January 1, 2020.
(b) Billing periods. Whenever the manager of transportation and infrastructure shall determine that it is necessary or appropriate, he may designate a sanitary sewer account to be billed other than monthly. Such a designation may be used for the convenience of the city or for accounts such as those including an industrial waste surcharge, water gain factor (well), water loss factor (e.g., evaporation or product usage) or high-volume water usage. For users who are designated for sanitary sewer billing on a different periodicity, those who qualify for charges under subsection (a)(1) or (2) of this section shall be charged at prorated amounts based on the rates shown in those subsections for each billing period. Otherwise, the charges will be computed as shown in subsections (a)(3), (4) or (5), as appropriate.
(c) CPI-U adjustment. On January 1, 2021, and annually thereafter, the current rates named above in subsection (a) of this section shall be adjusted, in an amount equal to the percentage change from the previous year in the CPI-U. The percentage change to be applied to the rates shall be calculated as follows:
CPI for current period, Less CPI for previous period:
Equals index point change
Divided by previous period CPI
Equals result multiplied by 100
Equals percent change
