(A) The basic user charge is levied on all users to recover the operation, maintenance plus replacement (O, M & R) cost and shall be based on a flat rate for non-metered customers and water meters for metered customers having the following normal domestic concentrations:
(1) A five-day, 20°C biochemical oxygen demand (BOD) of 250 mg/l; and
(2) A suspended solids content of 250 mg/l.
(B) The basic user charge may 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 water and wastewater facilities, including a replacement fund for the year, for all work categories; and
(3) Compute surcharge costs per pound for BOD and SS concentrations in excess of normal domestic strengths.
