§ 52.081   CONNECTION CHARGE PAYMENT; CHARGES A LIEN.
   (A)   The foregoing connection and construction charges shall be paid in full at the time of application for the building permit for any new structure, addition to an existing structure, or change of use within an existing structure; provided, however, that where a structure connected to the sewer was occupied prior to the effective date of this ordinance, the user shall have the option of paying installments as follows:
      (1)   The minimum sum of 25% of the total computed connection and construction charge for multiple unit connection shall be paid when the connection permit is issued by the city, and the balance shall be paid in 30 equal installments together with interest at 6% per annum of the declining balance from the date when the connection permit is issued.
      (2)   The first installment and accrued interest shall be due and payable on the next December 1, which is more than 3 months after the date when the connection permit is issued, and subsequent installments with accrued interest shall be due and payable on December 1, annually thereafter, and all installments with accrued interest shall be subject to the same interest, fees, and penalties as the city taxes on the premises.
      (3)   The balance of any connection charge or construction charge remaining unpaid may be paid in cash at any time with accrued interest to the date of payment. The balance due on a connection charge and construction charge for a given premises shall be paid in full at the time the premises changes ownership.
   (B)   Interest shall not commence until connection to the sewer shall be made. However, the connection charge shall be the connection charge which is established by ordinance on the date of connection rather than the date of application.
   (C)   All connection charges and all installments thereof, together with interest, fees, and penalties, shall constitute a lien upon the premises connected to the sewer; and the lien shall be enforced in the same manner as are liens for city taxes.
