(a) A proportionate rate for the operation, maintenance, and replacement of the sewage disposal system be charged to all users based upon the following formula:
OM&R = A/V
Where A = Total annual operation, maintenance and replacement costs for the wastewater treatment collection system.
V = Total metered volume of water used per year by users of the system.
(b) Debt/Capital Improvement Charge (DCIC). The rate for repayment of capital costs associated with the construction of the sewage improvements shall be charged to all users based upon the following formula:
DCIC = B/V
Where B = Total amortized annual debt/capital improvement costs.
V = Total metered volume of water used per year by users of the system.
(c) Calculation of Charges. The sewer service charge for each user shall be calculated by multiplying the currently adopted OM&R rate and DCIC rate, determined as above, by the actual water meter reading in 1,000 gallon increments.
(d) Surcharge. Sewerage or industrial wastes above normal domestic sewage strength, but acceptable for discharge into the sanitary sewerage system shall be subject to a surcharge. The surcharge shall be determined on the basis of either or both of two constituents of water or wastes:
(1) Total suspended solids, and/or
(2) Five-day BOD at 20 degrees C., and as herein provided.
Formula for SS:
SS rate = AC
Where A = Annual cost of treating suspended solids.
C = Total annual pounds of solids treated.
(e) Usage Charge. All users of the sanitary sewerage system shall be charged a sewer service charge based on usage of the system. No free service will be granted to any user of the system. Charges shall be determined as follows:
BOD rate = B/D
Where B = Annual cost for treating biochemical oxygen demand.
D = Total annual pounds of BOD
When either or both the total suspended solids and the BOD of a water or waste accepted for admission to the system exceeds the values of their constituents for normal sewage, the excess concentration in either or both, as the case may be, shall be subject to a surcharge as follows:
(1) Pounds of excess suspended solids per day x $.18/lb = Suspended Solids Surcharge.
(2) Pounds of excess BOD per day x .22/lb = BOD Surcharge.
In addition to the surcharge, the user will pay the user charge as defined in Section 1.
The pounds of BOD per days and/or pounds of suspended solids per day, above the concentration previously described for formal strength systems, shall be determined by the Village or their authorized representative.
In addition to a surcharge on BOD and suspended solids, the Village shall have the right to surcharge any user for the discharge of any other pollutants into the sewage system.
(f) Annual Review of Charges.
(1) The sewer service charge and user charges shall be reviewed annually by the Village of New Concord in order to determine whether or not they are sufficient to defray the fixed charges, amortization costs, and annual cost of operation and maintenance of the sewerage system. If the difference between the total annual revenue derived and the total annual cost is sufficient to justify an increase or decrease in the sewer service or user charges, the Village will adjust to maintain a proportional user charge.
(2) Each user is to be notified at least annually, in conjunction with a regular bill, or the rate and that portion of the sewer service charge which is attributable to OM&R costs of wastewater treatment services.
