Any owner of land situated in any drainage district of the State of Mississippi, which has an outstanding bonded indebtedness, may secure the release of his land or any part thereof from the lien of the assessment of benefits thereon for drainage purposes by paying to the drainage commissioners the full amount of the outstanding assessed benefits against his property or any part thereof. The drainage commissioners or their duly authorized officer, upon receipt of said fund, shall execute to the property owner a full release of his land from the lien of said assessment and acknowledge said release, which may be recorded by the owner in the office of the chancery clerk of the county where said land is situated. However, nothing herein shall have the effect of releasing any land situated in a drainage district from its liability for annual maintenance taxes as now or which may hereafter be levied.
