The charge system and Sanitary Sewer Fund shall be administered according to the following provisions:
(A) (1) The Finance Department shall maintain a proper system of accounts suitable for determining the operation and maintenance, equipment replacement and debt retirement costs of the treatment works, and shall furnish the City Council with a report of the costs annually.
(2) The City Council shall annually determine whether or not sufficient revenue is being generated for the effective operation, maintenance, replacement and management of the treatment works, and whether sufficient revenue is being generated for debt retirement.
(3) The city shall reassess and as necessary revise the sewer service charge system then in use to insure the proportionality of the user charges and to insure the sufficiency of funds to maintain the capacity and performance to which the facilities were constructed, and to retire the construction debt.
(B) Bills for sewer service charges shall be rendered on a monthly basis succeeding the period for which the service was rendered. Any bill not paid by the due date will be considered delinquent.

The penalty shall be computed at a rate of interest prescribed by Council.
(C) The owner of the premises may be liable to pay for the service to the premises, as determined by the Council, and the service is furnished to the premises by the city only upon the condition that the owner of the premises is liable therefore to the city.
(D) Any additional costs caused by discharges to the sanitary sewerage facilities of toxic or other incompatible wastes, including the cost of restoring wastewater treatment services, clean up and restoration of the receiving waters and environs, and sludge disposal, shall be borne by the discharger(s) of the wastes, at no expense to the city.
