Definitions. The following terms shall have the following meanings under this section:
DEBT SERVICE CHARGES
All costs associated with repayment of debts incurred for the construction and/or rehabilitation of a wastewater collection system and treatment facility.
NORMAL DOMESTIC STRENGTH WASTEWATER
Wastewater with concentrations of CBOD, suspended solids, total kjeldahl nitrogen and total phosphorus no greater than 200, 250, 40 and 10 milligrams per liter, respectively.
NORMAL USER
A user whose contributions to the sewerage system consist only of normal domestic strength wastewater originating from a house, apartment, flat, or other living quarters occupied by a person or persons constituting a distinct household, business or commercial enterprise.
OPERATION AND MAINTENANCE COSTS
All costs associated with the operation and maintenance of the sewerage system.
REPLACEMENT COSTS
All costs necessary 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 for only replacement of equipment.
SEWER SERVICE CHARGE
A service charge levied on users of the sewerage system for payment of capital expenses as well as the operation and maintenance costs, including replacement of said facilities.
B. 
Policy. It shall be the policy of the Village of Maple Bluff to obtain sufficient revenues to pay the costs of the operation and maintenance of the sewerage system, including a replacement fund (i.e., a cash account to be used for future expenditures for obtaining or installing equipment, accessories or appurtenances which are necessary to maintain the capacity and performance of the sewerage system during the service life for which such facilities were designed and constructed), through a system of sewer service charges as defined in this section. The system shall assure that each user of the sewerage system pays its proportionate share of the cost of such facilities.
C. 
Basis for service charge. The semiannual service charge shall be sufficient to pay the billing and customer-related administration expense and the operation and maintenance expenses, including any replacement of the sewerage system. The rates in this section shall be reviewed not less than biennially. Rates shall be adjusted as required to reflect actual number and size of users and actual costs. Users will be notified annually of the portion of service charges attributable to operation and maintenance.
D. 
Sewer service charges. A sewer service charge is hereby 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 sewerage system. Such sewer service charge shall be payable as hereinafter provided and in amount determined as follows:
(1) 
Category A service charges shall be imposed on users whose water use is metered and whose sewer discharges are normal domestic strength wastewater. The Category A sewer service charge is of the following form:
Service Charge
=
Customer Charge + Volume Charge
Customer Charge
=
A flat rate based on the size of the water meter
Volume Charge
=
A volume of metered water in hundred cubic feet multiplied by a volume rate
Volume Rate
=
The volume unit price expressed in dollars per 100 cubic feet
(2) 
Category B service charges shall be imposed on users whose water use is not metered and whose sewage discharges normal domestic strength wastewater. The Category B service charge shall be of the form as follows: Service Charge = Equivalent Residential Units multiplied by the Equivalent Residential Unit Rate. No user shall be assigned less than one equivalent residential unit. The number of residential unit equivalents for nonresidential users shall be as determined by the Sanitary District Commissioners.
(3) 
Category C service charges shall be imposed on users whose sewage discharges are high-strength wastewater having concentrations of carbonaceous biochemical oxygen demand (CBOD) greater than 200 milligrams per liter (mg/l) and/or suspended solids greater than 250 milligrams per liter (mg/l) and/or total kjeldahl nitrogen (TKN) greater than 40 milligrams per liter (mg/l) and/or total phosphorus (TP) greater than 10 milligrams per liter (mg/l). The minimum Category C service charge shall be based on a concentration of 200 mg/l CBOD, 250 mg/l suspended solids, 40 mg/l TKN, and 10 mg/l total phosphorus. The form of the Category C service charge is as follows: Service Charge = Customer Charge + Volume Charge + High Strength Surcharge. The customer charge and the volume charge are similar to those components of the Category A service charge.
(4) 
The high-strength surcharge equals the excessive CBOD, suspended solids, TKN, and total phosphorus multiplied by the respective CBOD, suspended solids, TKN and total phosphorus rates. The excessive CBOD, suspended solids, TKN and total phosphorus are the portions of each of these constituents that are in excess of normal domestic strength wastewater. The excessive amounts of CBOD, suspended solids, TKN and total phosphorus are expressed in pounds and their respective rates are expressed in dollars per pound.
E. 
Reassignment of sewer users. The Village of Maple Bluff will reassign sewer users into appropriate sewer service charge categories if wastewater sampling programs and other related information indicate a change of categories is necessary.
F. 
The Village will maintain proportionate distribution of operation, maintenance, and replacement costs.
G. 
The user charge takes precedence over preexisting agreements inconsistent with the regulations of this program.
[1]
Editor's Note: The schedule of current charges is on file with the Village Clerk-Treasurer.
A. 
Collection. Service charges and industrial cost recovery charges shall be billed semiannually. Payments shall be made within 20 days of the billing date. Interest of 1 1/2% per month shall accrue on bills from and after the date payment is due.
B. 
Delinquent payments. Delinquent payments shall be collected in the manner provided by §§ 66.0821 and 200.13(2), Wis. Stats.
C. 
Disposition of revenue. The amounts received from the collection of charges authorized by this article shall be credited to a sanitary sewerage account which shall show all receipts and expenditures of the sewerage system. Charges collected for replacement expenses shall be credited to a segregated, nonlapsing replacement account. These funds are to be used exclusively for replacement. When appropriated by the Village of Maple Bluff, the credits to the sanitary sewerage account shall be available for the payment of the requirements for operation, maintenance, repairs, and depreciation of the sewerage system consistent with 40 CFR 35.929. Any surplus outside the purview of 40 CFR 35.929 in said account shall be available for the payment of principal and interest of bonds issued and outstanding, or which maybe issued, to provide funds for said sewerage system, or part thereof, and all or a part of the expenses for additions and improvements and other necessary disbursements or indebtedness, and the Village of Maple Bluff may resolve to pledge each surplus or any part thereof for any such purpose. All present outstanding sewer system general obligation bonds, including the refunding bonds, shall be paid from this fund as to both principal and interest.
Any person found in violation of the Sewer Use Ordinance of the District or of any prohibition, limitation or requirement contained therein shall be subject to the procedures and penalties therein pertaining. Any such violation occurring within the Village shall, in addition, be a violation of this article, subject to the penalties imposed under this chapter.
No person shall knowingly make any false statement, representation, record, report, plan or other document filed with the municipality or the District or falsify, tamper with or knowingly render inaccurate any monitoring device or method required under this article or the District Ordinance.
