§ 51.091 BASIC USER CHARGE.

   The basic user charge is levied on all users to recover the operation, maintenance, plus replacement (OM&R) costs and shall be based on water usage as recorded by water meters or sewage meters for wastes having the following normal domestic concentrations:

   (A)   A five day, 20°C biochemical oxygen demand (BOD) of 250 mg/l;

   (B)   A suspended solids content of 250 mg/l; and

   (C)   The basic user charge shall be computed as follows:

      (1)   Estimate the annual wastewater volume, pounds of BOD and pounds of SS to be treated;

      (2)   Estimate the projected annual revenue required to operate and maintain the wastewater facilities, including a replacement fund for the year, for all works categories;

      (3)   Proportion the estimated OM&R costs to each user class by volume, BOD, and SS;

      (4)   Proportion the estimated OM&R costs to wastewater facility categories by volume, BOD, and SS;

      (5)   Compute costs per 1,000 gallons for normal domestic strength sewage; and

      (6)   Compute surcharge costs per pound for BOD and SS concentrations in excess of normal domestic strengths.
