            1.   Residential;
            2.   Commercial;
            3.   Industrial;
            4.   Institutional; and
            5.   Governmental.
         (b)   The allocation of users to these categories for the purpose of assessing user charges and debt service charges shall be the responsibility of the City Engineer. Allocation of users to user classes shall be based on the substantive intent of the definitions of these classes contained herein.
      (2)   Rates for concentrations. The user shall pay operation, maintenance and replacement costs in proportion to the user’s proportionate contribution of wastewater flows and loadings to the treatment plant, with the minimum rate for loadings of BOD and of TSS being the rate established for concentrations of 270 mg/l BOD and 240 TSS (i.e., normal domestic strength wastewater).
      (3)   Unit costs for treatment of flow, BOD and TSS.
         (a)   Unit costs for treatment of flow, BOD and TSS shall be determined and fixed annually in the sewer service charge system according to the following procedure:
            1.   Determine the annual OM&R budget;
            2.   Allocate total annual OM&R costs to flow, BOD and TSS proportionately; according to the costs of collection, and of the specific treatment processes required to affect or reduce flow, BOD and TSS; and
            3.   Divide the OM&R costs attributable to flow, BOD and TSS respectively, by the total annual billable volume and loadings of flow, BOD and TSS, to arrive at unit costs.
         (b)   For purposes of determining, the following definitions of unit costs shall apply:
         UF   =   Unit cost for treatment of flow in $/Kgal.
         UBOD   =   Unit cost for treatment of BOD in $/lb.
         UTSS   =   Unit cost for treatment of TSS in $/lb.
         (c)   Unit costs for 1986 are provided in Table 6 of the sewer service charge system developed with the assistance of John Baker Engineering, Inc. Subsequent calculations of unit costs shall be according to the substantive intent of this SSCS.
         (d)   The calculation of unit cost for treatment of normal domestic strength wastewater shall be as follows:
UN = COMR
TBWV
         Where:
         UN   =   Unit cost for operation, maintenance and replacement to treat domestic strength wastewater in S/K gal.
         COMR   =   Total annual OM&R costs less costs associated with the treatment of concentrations greater than normal domestic strength.
         TBWV   =   Total annual billable wastewater volume in k gallons.
      (4)   User charges for normal domestic strength users.
         (a)   Calculating billable flows and loadings.
            1.   General. The billable amount of flow will be calculated from the volume of metered water usage. For residential users, the per month billable flow shall be equal to monthly metered water usage as determined by the first quarter of the calendar year. For non-residential users discharging NDSW, billable flow shall be equal to monthly water usage measured throughout the year.
            2.   Determination of loadings from metered water usage. The billable amounts of BOD and TSS will be calculated from the volume of metered water usage, as determined above, where the billable quantities will be those attributable to a wastewater concentration of 270 mg/l BOD and 240 mg/l TSS (i.e., “normal domestic strength wastewater”).
         (b)   Calculating user charges.
UC (NDS) = (UNxF)
         Where:
         UC (NDS)   =   User charge for treatment of normal domestic strength wastewater.
         UN   =   Unit cost for operation, maintenance and replacement to treat normal domestic strength wastewater.
         F    =   Billable flow in Kgal.
      (5)   User charges for users contributing wastes greater than normal domestic strength.
         (a)   Calculating billable flows and loadings. The billable amount of flow will be calculated from the volume of metered water usage, or at the discretion of the city, from the measurement of effluent flow at user’s point of discharge. Measurements shall be according to a regular program prescribed by the city. The billable amounts of BOD and TSS will be calculated by the measurement of these wastes according to a program prescribed by the city in keeping with the latest edition of Standard Methods for the Examination of Water and Wastewater.
         (b)   Calculating user charges.
UC(GNDS) = (UF x F) + (UBOD) + (UTSS x QTSS)
                  Where:
         UC(GNDS)   =   User charge for treatment of wastewater that is greater than normal domestic strength.
         UF   =   Unit cost for treatment of flow in $/Kgal.
         F   =   Billable flow in Kgal.
         UBOD   =   Unit cost for treatment of BOD in $/lb.
         QBOD   =   Quantity of BOD in lbs.
         UTSS   =   Unit cost for treatment of TSS in $/lb.
         QTSS   =   Quantity of TSS in lbs.
         (6)   Meter installation. The city may, at its discretion, require nonresidential users to install wastewater flow meters or such additional water meters as may be necessary to determine wastewater volume. The city may require residential connections to install water meters for the purpose of determining wastewater volume. When so required, the meters shall be of a type approved by the city equipped with remote registering recorders, and located at an accessible site on the owner’s property.
      (7)   Recovery of local construction costs. Local construction costs for the wastewater treatment facility will be recovered from users according to their contribution of wastewater flows and loadings into the treatment facility as follows:
Dc = Cd
    F
                  Where:
         DC   =   Annual debt service charge.
         Cd   =   Annual debt service cost.
         F   =   Billable flow in Kgal.
      (8)   Sewer service charge.
SSC = UC + DC
         Where:
         SSC   =   Annual sewer service charge.
         UC   =   Annual user charge.
         DC   =   Annual debt service charge.
   (D)   Sewer Service Fund.
      (1)   The city hereby establishes the Sewer Service Fund as an income fund to receive all revenues generated by the sewer service charge system, and all other income dedicated to the operation, maintenance, replacement and construction of the wastewater treatment works, including taxes, special charges, fees and assessments intended to retire construction debt. The city also establishes the following accounts as income and expenditure accounts within the Sewer Service Fund:
         (a)   Operation and Maintenance Account;
         (b)   Equipment Replacement Account; and
         (c)   Debt Retirement Account.
      (2)   All revenue generated by the sewer service charge system, and all other income pertinent to the treatment system, including taxes and special assessments dedicated to retire construction debt, shall be held by the treasurer separate and apart from all other funds of the city. Funds received by the Sewer Service Fund shall be transferred to the Operation and Maintenance Account, the Equipment Replacement Account and the Debt Retirement Account in accordance with state and federal regulations and the provisions of this section.

The Council shall annually determine whether or not sufficient revenue is being generated for the effective operation, maintenance, replacement and management of the treatment works, and whether sufficient revenue is being generated for debt retirement. The Council will also determine whether the user charges are distributed proportionately to each user in accordance with division (B) above and § 204(b)(2)(A) of the Federal Water Pollution Control Act, being 33 U.S.C. § 1284(b)(2)(A), as amended. The city shall, thereafter, but not later than the end of the year, reassess and as necessary revise the sewer service charge system then in use to ensure the proportionality of the user charges and to insure the sufficiency of funds to maintain the capacity and performance to which the facilities were constructed, and to retire the construction debt.
      (2)   In accordance with federal and state requirements each user will be notified annually in conjunction with a regular billing of that portion of the sewer service charge attributable to operation, maintenance and replacement.
      (3)   In accordance with federal and state requirements, the City Clerk shall be responsible for maintaining all records necessary to document compliance with the sewer service charge system adopted.
      (4)   Bills for sewer service charges shall be rendered on a quarterly basis succeeding the period for which the service was rendered and shall be due 30 days from the date of rendering. Any bill not paid in full 30 days after the due date will be considered delinquent. At that time, the city shall notify the delinquent owner/occupant in writing regarding the delinquent bill and subsequent penalty. The penalty shall be computed as 5% of the original bill and shall be increased the same 5% for every quarter the bill is outstanding.
      (5)   The owner of the premises, shall be liable to pay for the service to the premises, and the service is furnished to the premises by the city only upon the condition that the owner of the premises is liable therefor to the city.
      (6)   Any additional costs caused by discharges to the treatment works of toxics or other incompatible wastes, including the cost of restoring wastewater treatment services, clean up and restoration of the receiving waters and environs, and sludge disposal, shall be borne by the discharger(s) of the wastes, at no expense to the city.
   (F)   Service charges a lien.
      (1)   Each and every sewer service charge levied by and pursuant to this section is hereby made a lien upon the lot or premises served, and all charges which are on January 1 of each year past due and delinquent, shall be certified to the County Auditor as taxes or assessments on the real estate. Nothing in this section shall be held or construed as in any way stopping or interfering with the right of the city to levy as taxes or assessments against any premises affected any delinquent or past due sewer service charges.
      (2)   In addition to all penalties and costs attributable and chargeable to recording notices of the lien or filing a civil action, the owner or user of the real estate being serviced by the treatment works shall be liable for interest upon all unpaid balances at the rate of 8% per annum.
   (G)   System to take precedence. The sewer service charge system shall take precedence over any terms or conditions of agreements or contracts which are inconsistent with the requirements of § 204(b)(1)(A) of the Act, being 33 U.S.C. § 1284(b)(10(A) and 40 C.F.R. § 35.2140 of the Environmental Protection Agency’s grant regulations.

      (1)   Temporarily during new construction;
      (2)   Temporarily during an emergency to prevent danger to persons or property;
      (3)   For a period of not more than seven months when soil conditions make excavation for underground service impractical; or

   (C)   Electrical installations. All electrical installations shall comply with the following, where applicable.
      (1)   Motors of 20 HP or more must have line compensators on same; provided, however, that, the city may, at its option, make an exception if the total connected motor load required is smaller than the consumer connected load, and the motor starting current is less than the current corresponding to the consumer’s total connected load.
      (2)   Any establishment having a total motor load of 125 HP or more is required to have 440 volts for its motor load.

      (1)   Converting to underground. The city may, at its option and at its expense, convert any present service where no change is otherwise required by the consumer, from overhead to underground. Where this is done, the city shall only cover and refill the trench and other ditching maintenance or repair, and all subsequent changing and repairing of the service shall be the obligation of the consumer.
      (2)   Replacing. Nothing herein shall prevent the city from replacing an overhead service with the same type.
      (3)   Meters and placement service. Placement of service and meters shall be determined by the city.
