When a separate district has been established or abolished under Section 65-19-11 or Section 65-19-13, the said establishment or abolishment shall not release the territory or taxable property or persons of the former district or districts or parts thereof from assessments for the benefit and purposes of the original district or districts or parts thereof, nor impair nor in any wise release the property or persons in the new district so established from assessment and liability for the payment of the debts and obligations of the original district. In the respects last aforesaid, the creation of such new district as in the foregoing sections provided shall in no wise change the lines or territorial construction and integrity of the original district or districts or parts thereof from which such new district may be formed. In event a separate road district is consolidated or added to or otherwise established or abolished, as in the foregoing sections provided, out of territory embraced in whole or in part within any district that has outstanding bonds or loan warrants or other valid indebtedness, the board of supervisors shall annually levy a tax on the territory that originally issued said bonds or loan warrants or incurred the indebtedness, in accordance with the contract under which such indebtedness was created, until the same is fully paid.
