6-1-1: APPORTION COSTS:
   A.   Determine Annual Cost Of Operation And Maintenance: The city/Town shall determine the total annual costs of operation and maintenance of the wastewater systems which are necessary to maintain the capacity and performance, during the service life of the treatment works, for which such works were designed and constructed. The total annual cost of operation and maintenance shall include, but need not be limited to, labor, repairs, equipment replacement, maintenance, necessary modifications, power, sampling, laboratory tests and a reasonable contingency fund.
   B.   Wastewater User's Contribution Percentage: The city/Town shall determine for each user or user class, the average daily volume of wastewater discharged to the wastewater system, which shall then be divided by the average daily volume of all wastewater discharged to the wastewater system to determine such user's volume contribution percentage. The amount used as the total average daily volume of wastewater shall exclude infiltration and inflow.
The city/Town shall determine for each user or user class, the average daily total suspended solids (TSS) poundage discharged to the wastewater system, which shall then be divided by the average daily poundage of all TSS discharged to the wastewater system to determine such user's TSS contribution percentage. The volume contribution percentage, BOD contribution percentage, and TSS contribution percentage for each user class shall be multiplied by the annual operation and maintenance costs for wastewater treatment of the total volume flow, total five (5) day twenty degree centigrade (20°C) BOD and total TSS, respectively.
   C.   Surcharge System For Users With Excess BOD And TSS: The city/Town will assess a surcharge rate for all nonresidential users discharging wastes with BOD and TSS strengths greater than the average residential user. Such users will be assessed a surcharge sufficient to cover the cost of treating their above- normal strength wastes. Normal strength wastes are considered to be two hundred (200) ppm BOD and two hundred fifty (250) ppm TSS. The surcharge rate structure for such above-normal strength waste discharge as follows:
   EXCESSIVE SEWAGE STRENGTH
   SURCHARGE FORMULA*
   Where:
 
S
=
Vs x 8.34 (($0.0824) (BOD-200) + ($0.0616) (SS-250))
S
=
Surcharge in dollars
Vs
=
Sewage volume in million gallons
8.34
=
Pounds per gallon of water
BOD
=
BOD strength index in parts per million by weight
200
=
Allowed BOD strength in parts per million by weight
SS
=
Suspended solids strength index in parts per million by weight
250
=
Allowed SS strength in parts per million by weight
 
   * Subject to annual review and revision.
(Ord. 99-03, 11-16-1999)
   D.   User's Wastewater Service Charge: Each nonresidential user's wastewater treatment cost contributions as determined in Sections 6-1-2 and 6-1-3 of this Chapter shall be added together to determine each user's annual wastewater service charge. Residential users may be considered to be one class of user and equitable service charge may be determined for each user based on an estimate of the total wastewater contribution of this class of user. The governing body may classify industrial, commercial and other nonresidential establishments as a residential user; provided, that the wastes from these establishments are equivalent to the wastes from the average residential user with respect to volume, total suspended solids, and BOD. Each user's wastewater treatment cost contribution will be assessed in accordance with the following rate schedule:
