(A) (1) The charge for operation and maintenance shall be determined by the flow measured by the water meter at each user’s premises and in cases of use by other than general municipal users, by the pollutant concentrations of the sewage.
(2) The unit cost for flow shall be calculated by dividing the Category B (Operation and Maintenance) cost by the total metered flow sold to users of the wastewater disposal system.
(B) Users discharging wastewater exceeding the BOD, suspended solids (SS) and/or ammonia parameters of the general municipal flow shall pay an additional charge pro rata. The unit cost for BOD, SS and ammonia shall be calculated by apportioning the Category B (Operation and Maintenance) cost to flow, BOD, SS and ammonia; and then dividing each cost so apportioned by the total billable flow, BOD, SS and ammonia received at the wastewater treatment facility in that year. The user charge shall be the sum of the products obtained by multiplying the unit costs as determined above by the user’s actual flow, BOD, SS and ammonia during the billing period.
(C) In addition to the charges provided for herein, the village must impose a surcharge on any user pursuant to Chapter 51 of this code of ordinances or based on some other pollutant loading factor which requires special treatment at the wastewater treatment works.
(D) (1) Facilities not having a water supply that is metered or if the meter readings are not available, shall be charged based on the flow anticipated from a typical single-family dwelling. The typical single-family dwelling shall be assigned a flow value of 1 and shall pay for the wastewater disposal system use on a fixed monthly charge basis.
(2) Using this basic charge, sewer service charges for the other than residential dwellings shall be calculated by the village as follows:
(a) Each unit of the townhouse shall have a value of 1;
(b) Condominiums, duplex units and apartments shall have a value of 1.0 for each living unit;
(c) Mobile homes shall have a value of 1.0;
(d) Commercial and industrial building units shall be assigned a minimum value of 1 living unit;
(e) Other buildings and structures not listed in the table below shall be assigned a value of 1 for each multiple of the estimated annual wastewater discharge anticipated from the typical single- family dwelling;
(f) All non-family dwellings may be required to install and maintain water meters at no charge to the village. The village reserves the right to require annual tests to ensure accurate flow.
(3) The following is a listing of standards used in assigning the flow value for various commercial, public and institutional facilities.

(E) There shall be a minimum monthly sewer service charge that shall be equal to the debt service charge based on the flow anticipated from a typical single-family dwelling plus the administrative charge. The minimum charge shall be levied when no wastewater is discharged by a user during one complete billing period.
(F) Unmetered users may install their own meter and be charged in the same manner as metered customers if the meter is installed and maintained pursuant to all village rules and regulations.
(G) If a substantial portion of the water utilized by any user is not discharged into the sewer system, the volume of such water shall be deducted in computing the sewer use charge, provided a separate meter is installed to measure such volume. The user desiring to install such separate meter shall make application and payment for the meter to the village and engage, at his or her own expense, a plumber to affect the necessary piping changes and install the couplings so the meter can be set. The user may also make direct payment to the distributor for the necessary meter provided it is approved by the village.
