The following terms shall have the following meanings under this article:
DEBT SERVICE CHARGES
Includes all costs associated with repayment of debts incurred for the construction and/or rehabilitation of wastewater collection system and treatment facilities.
NORMAL DOMESTIC STRENGTH WASTEWATER
Wastewater with concentrations of BOD5 no greater than 250 milligrams per liter (mg/L) and suspended solids no greater than 250 milligrams per liter (mg/L).
NORMAL USER
A user whose contributions to the sewerage system consist only of normal domestic strength wastewater originating from a house, apartment or other living quarters occupied by a person or persons constituting a distinct household, business or commercial enterprise.
OPERATION AND MAINTENANCE (O&M) COSTS
Includes all costs associated with the operation and maintenance of the wastewater collection and treatment facilities. These costs, including costs associated with clear water flows (I/I), shall be divided proportionately among the various sewer users.
REPLACEMENT COSTS (R)
Include all costs necessary to accumulate the resources to replace equipment as required to maintain capacity and performance during the design life of the facility. A separate, segregated, distinct replacement fund shall be established and used only for replacement of equipment designated by the fund.
SEWER SERVICE CHARGE
A service charge levied on users of the sewer system for payment of debt service, operation and maintenance costs, including Replacement of said facilities.
It shall be the policy of the Village to obtain sufficient revenues to pay the costs for the debt service, operation and maintenance of the wastewater facilities, including a replacement fund, through a system of sewer service charges, as defined in this article. The system shall assure that each user of the wastewater facilities pays his proportionate share of the cost of such facilities.
A. 
The sewer service charge shall be based on an equivalent unit rate structure.
B. 
The sewer service charge shall be sufficient to pay the costs of debt service, operation and maintenance, including any replacement fund, of the wastewater facilities. The Village Board has provided the initial estimates of number of users, costs, etc., to calculate the first year's user charges. The rates in this chapter shall be reviewed not less than biennially. Such review will be performed by the Village Board. Rates shall be adjusted, as required, to reflect the actual number and size of users and actual costs.
C. 
Users shall be notified annually of the portion of service charges attributable to operation, maintenance and replacement.
A. 
A residential equivalency charge (REC) is hereby imposed upon each lot, parcel of land, building or premises served by the sewerage system or otherwise discharging sewage, including nondomestic and industrial wastes, into the system. Such charge shall be payable as herein provided and shall be on the basis of one unit for each residential equivalent unit. Each single-family dwelling shall be assigned one unit.
B. 
A single-family dwelling is defined as a mobile home, a seasonal dwelling, a duplex unit, an apartment unit, a single-family detached dwelling or a multifamily unit.
C. 
A REC is hereby imposed on all users of the sewerage system, based upon the actual cost of debt, operation, maintenance and replacement. On or before October 15 of each year, the Village Clerk-Treasurer shall recompute the sewer use charge. This charge shall be computed by dividing the proposed net yearly debt service, operation, maintenance and replacement budget as provided in this chapter by the total number of residential user equivalent (RUE) units.
D. 
On or before October 15 of each year, the Village Clerk-Treasurer shall recompute the assignment of residential equivalent units to all users within the system. In no event shall each customer be assigned a residential equivalent unit that is less than one unit. A list of assigned RUE units is included in Appendix A. A new user will be assigned an initial RUE unit based on Appendix B.[1]

Editor's Note: Current copies of Appendixes A and B are on file in the Village Clerk-Treasurer's office.
E. 
The residential equivalency charge (REC) shall be as set by the Village Board.[2]

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
F. 
There shall be no discounted rates levied on vacated buildings or premises served by the sewerage system or discontinued services.[3]

Residential equivalency charge shall be payable as hereinafter provided and in an amount determinable as follows:
A. 
Category A is defined as normal or domestic strength wastewater having organic concentrations of biochemical oxygen demand (BOD5) no greater than 250 milligrams per liter (mg/L) and suspended solids no greater than 250 milligrams per liter (mg/L). The residential equivalency charge (REC) for Category A wastewater is calculated as follows:
REC
=
(Debt + Replacement + O&M)/number of residential equivalent users
B. 
Category B is defined as wastewater having organic concentrations of biochemical oxygen demand (BOD5) greater than 250 milligrams per liter (mg/L) and/or suspended solids (SS) greater than 250 milligrams per liter (mg/L). The sewer use charge for Category B wastewater is calculated as follows:

Category C is defined as septage which has organic concentrations of biochemical oxygen demand (BOD) greater than 250 milligrams per liter (mg/L) and/or suspended solids (SS) greater than 250 milligrams per liter (mg/L). The equation for the monthly Category C wastewater charge is calculated as follows:

It will be assumed that holding tank wastewater has a BOD of 600 mg/L and an SS of 1,800 mg/L and septic tank wastewater has a BOD of 5,000 mg/L and SS of 15,000 mg/L unless an actual analysis is furnished by the discharger. This concentration results in a holding tank charge of $49.76 per 1,000 gallons plus $18 and a septic tank wastewater charge of $182.97 per 1,000 gallons plus $18.[1]
