(a) The wastewater service charge for the use or and for the service supplied by the wastewater facilities of the Village shall consist of a basic user charge, a debt service charge, a capital improvement charge and any applicable surcharges.
(b) The basic user charge is levied on all users to recover the operation, maintenance and replacement costs and shall be based on water usage as recorded by water meters or sewage meters for wastes having the following normal domestic concentrations:
(1) A five-day, twenty-degree Centigrade biochemical oxygen demand (BOD) of 119 milligrams per liter.
(2) A suspended solids content of 168 milligrams per liter.

(f) The adequacy of the wastewater service charge shall be reviewed at least once a year by certified public accountants for the Village in their annual audit report. The wastewater service charge shall be revised periodically to reflect a change in local capital costs or operation, maintenance and replacement costs.
