(a) The assessments shall be a lien on all the lands of the district, in the nature of a mortgage, and shall bear interest at the rate of six percent (6%) per annum after thirty (30) days from the filing of the assessments in the county clerk's office, and until paid.
(b) If at any time before judgment, in any foreclosure proceeding brought to enforce the lien, it shall appear that an error has been made in the description of any of the lands embraced in the assessment or lists, the error shall be at once corrected, and the correction shall have the effect in all respects as if the error had not existed.
