§ 51.11 SEWER SERVICE CHARGES. 
   (A)   Sewer service and user charges are imposed upon each lot, parcel of land, building, or premises served by the public sewer and wastewater facilities, or otherwise discharging sewage, including industrial wastes, into the public sewer and wastewater facilities. The user charge shall be included in the sewer service charge, and be payable as hereinafter provided. The methodology of determining the user charge rates is given in the user charge system. The rate schedule will be reviewed annually and adjusted as necessary to maintain a proportional distribution of costs among the users.
   (B)   The sewer service charge for any lot, parcel of land, building, or premises within the corporate limits, and for any lot, parcel of land, building, or premises outside the corporate limits which is connected to the public sewer system, shall be based upon the quantity of wastewater generated as measured by the water meter or sewage meter in use as follows.
      (1)   CATEGORY A is defined as normal or domestic strength wastewater having organic concentrations of biochemical oxygen demand (BOD) no greater than 200 milligrams per liter (mg/l) and suspended solids no greater than 250 milligrams per liter (mg/l). The sewer service charge for Category A wastewater is as follows.
Minimum Sewer Service Charge Per Billing Period With One Customer on Each Meter
Meter Size Debt Portion
   5/8 inch   $3.15 per month
   1-inch   $7.90 per month
   1¼-inch   $12.60 per month
   1½-inch   $18.90 per month
   2-inch   $31.50 per month
   3-inch   $50.40 per month
   5-inch   $201.60 per month
   Volumetric user charge   $1.15 per 1000 gallons
      (2)   CATEGORY B is defined as wastewater having organic concentrations of biochemical oxygen demand (BOD) greater than 200 milligrams per liter (mg/l) and/or suspended solids greater than 250 milligrams per liter (mg/l). The minimum Category B charge for BOD and suspended solids will be based on a concentration of 200 mg/l for BOD and 250 mg/l for suspended solids. The sewer charge for Category B wastewater is as follows.
   SSC = Category A charge (service charge + volumetric charge)
      +   (BOD - 200) x V x .00834 x CB
      +   (SS - 250) x V x .00834 x CS
in which: SSC = Total Sewer Service Charge per quarter
         BOD = Biochemical Oxygen Demand expressed as mg/1
         SS = Suspended solids expressed as mg/1
         CB = BOD unit price $.18/1000 pounds
         CS = SS unit price $.35/1000 pounds
         V = Total volume of water used, thousand gallons
      (3)   When the user places wastewater in a holding tank so that the flow is distributed over a 20 to 24-hour period, no further adjustment in the user charge shall be made. When no holding tank is provided and used by the user, the sewer service charge aforesaid will be further adjusted by the hours of operation per day divided by hours discharged, to be averaged over the entire quarter (such as a user with an average operation of 12 hours per day would have the sewer service charge increased by 24/12 to arrive at the final user charge).
   (C)   Reassignment of sewer users. The approving authority will reassign users into appropriate sewer service charge categories if wastewater sampling programs and other related information indicate a change of categories is necessary.
   (D)   Additional charges. Additional charges shall be imposed upon each lot, parcel of land, building or premises served by public sewer and wastewater facilities located outside the boundaries of the approving authority, to equalize local capital costs. The additional charge shall result in a minimum charge equal to the debt charge for each user, according to the schedule for debt repayment from utility revenues. Additional charges shall be added to the sewer bill for each billing period.
