Kan. Stat. § 19-2661
If no revenue bonds are outstanding the board of county commissioners may establish a schedule of fees and charges for the use of such facility and all moneys received therefrom shall be placed in a fund to be known as the refuse disposal fund and shall be used only for the purpose of paying for the operation of such disposal facility, for the making of repairs or replacements or construction of additional facilities at such site or the replacement of equipment. At any time that there may be a surplus in such fund and there are outstanding general obligation bonds, such surplus shall be placed in a sinking fund which shall only be used for the purpose of redeeming bonds which were issued for the acquisition or improvement of such facility or equipment used in connection therewith.
If revenue bonds are issued the board of county commissioners shall establish a schedule of fees and charges for the use of the facility to produce revenue sufficient to pay the bonds and interest, and any revenue over and above the amount necessary to pay the revenue bonds and interest each year may be used for the operation of the facility and for maintenance and improvements of and related to such facility. The revenue shall be placed in a refuse disposal fund. If the revenue is not sufficient to provide for operation, maintenance and improvement after bond and interest payments are made, such operation, maintenance and improvement expense shall be paid from the general fund of such county.
