The sewerage service charge shall be for the corresponding period of the water bills and shall be payable to the Village not later than 20 days after the end of each period. A penalty of 1 1/2% per month shall be added to all bills not paid by the date fixed for final payment.
All sewage charges shall be a lien upon the property service pursuant to § 66.0821, Wis. Stats., and shall be collected in the manner therein provided.
The amounts received from the collection of charges authorized by this chapter 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, the credits to the sanitary sewerage account shall be available for the payment of the requirements for operations, 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 may be 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 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.
Additional charges shall be imposed upon each lot, parcel of land, building or premises served by public sewer and wastewater facilities located outside the boundaries of the Village to equalize local capital costs. Such additional charges shall result in a minimum charge for each user according to the schedule for debt repayment for utility revenues. Such additional charges shall be added to the sewer bill for each billing period.
Excess revenues collected from a user class will be applied to operation and maintenance costs attributable to that class for the next year.
The Village shall conduct an annual audit, the purpose of which shall be to maintain the proportionality between users and user classes of the user charge system and to ensure that adequate revenues are available relative to increasing operation, maintenance and replacement costs.
