Kan. Stat. § 19-27a23
Whenever the board of county commissioners which has established a sewer district determines that because of abnormal delinquency in the payment of special assessments against property located within the district there will be insufficient revenue available to meet the present and future bond and interest maturities of bonds issued for the construction of sewers within the district, the board is hereby authorized to levy an annual tax of not to exceed 2 mills upon all of the taxable real property located within the district for the purpose of providing funds to supplement those funds received from special assessments thereby eliminating the deficiency. All moneys received from the payment of the delinquent special assessments made against property located within the sewer district shall be paid into the bond and interest fund of the district and used only for the purpose of paying the principal and interest of bonds issued for the construction of sewers in the district.
