The user fees for those properties utilizing City utilities is part of a consolidated statement for utility customers, which is generally paid for by a single payment. In the event that a partial payment is received, the payment shall be applied pro rata to each account billed on the consolidated statement in the proportion that an individual account bears to the total consolidated statement of all current charges for all accounts.

In addition to any other remedies or penalties provided by this or any other ordinance of the City of Arnold, failure of any user of City utilities within the City of Arnold to pay said fees promptly when due shall subject such user to discontinuance of utility services and the Public Works Director of the City, or the director's designee, is hereby empowered and directed to enforce this provisions as to any and all delinquent users.

In the event of such action, the City shall be entitled to recover all court costs and reasonable attorney fees for such collection. In the case that a tenant in possession of any premises or buildings shall pay said charges, it shall relieve the landowner from such obligation and lien; but the City shall not be required to look to any person whatsoever other than the owner for the payment of such charges. No changes of ownership or occupation shall affect the application of this Article, and the failure of any owner to learn that he/she purchases property against which a lien for user fees exist shall in no way affect his/her responsibility for such payment.

A. 
All storm water management user fees collected by the City shall be paid into a separate fund which is hereby created to be known as the "Watershed Stewardship Program Fund". Such fund shall be used for the purpose of paying the costs of construction, operation, administration, and maintenance of the system and to carry out all other purposes of the program. To the extent that the storm water management user fees collected are insufficient to construct, operate, and maintain the needed system, the cost of the same may be paid from such City funds as may be determined by the City Council, but the City Council may order the reimbursement of such funds if additional charges are thereafter collected. When the fund has surplus dollars on hand in excess of current needs, the surplus dollars will be invested to return the highest yield consistent with proper safeguards.
B. 
The fees and charges paid shall not be used for general or other governmental or proprietary purposes of the City, except to pay for the equitable share of the cost of accounting, management and government thereof. Other than as described above, the fees and charges shall be used solely for the purpose stated in Subsection (A) of this Section.
