Kan. Stat. § 24-714
This act shall be liberally construed, to promote the drainage of wet or overflowed lands; and the collection of assessments shall not be defeated by reason of any defect in the proceedings occurring prior to the judgment of the court approving and affirming the assessments of benefits and damages and ordering the work established: Provided, only, The court had jurisdiction, but such judgment shall be conclusive that all prior proceedings were regular and according to law, nor shall any person, at any stage of the proceeding, be permitted to take advantage of any error, defect or informality which does not directly affect himself. Should it appear at any time that the assessment of benefits is insufficient to complete the work and pay expenses in connection therewith, the commissioners of drainage appointed in said proceedings may file their petition setting forth the fact of such deficiency, and asking the court for authority to make an additional assessment.
Ten days' notice of the hearing of such petition shall be given to every person or corporation assessed for such work, or to the attorney of record of such person or corporation, which notice shall be given and served in the same manner as the notice of the hearing of the original petition, except that ten days' notice to residents of the county shall be sufficient, and publication once in the same newspaper in which the notice of the hearing of the original petition has been published, ten days prior to the date fixed for the hearing of such supplemental petition, shall be sufficient. On or before the expiration of such ten days' notice, any person interested may file an answer or objection to such petition. The court, after the expiration of such time, or after the hearing of the answers or objections, if any be filed, and if satisfied of the necessity therefor, may make an order authorizing the commissioners to make an additional assessment on all the lands originally assessed as benefited, and in proportion to such original assessment; and the same, or so much thereof as may be necessary, shall be first liens upon the lands against which they are assessed, and shall be collected as hereinbefore provided in case of the original assessment.
The drainage commissioners or any person interested in such work may also file with the court a supplemental petition, showing that lands not assessed for benefits or damages are affected, as the petitioner believes, by such drainage, whether such lands are or are not described in the petition or in either report of the commissioners. Notice of the hearing of such supplemental petition shall be given as provided in case of the filing of the original petition. The court shall refer such supplemental petition to the drainage commissioners appointed in said proceeding, to report thereon; and all proceedings may be had thereon and orders and decrees made in relation thereto, including the construction of additional arms and branches, as if it were the original petition; but the proceeding thereon shall not affect the original petition, unless the court for good cause, shall order the petitions consolidated. Any such order, however, shall not hinder or delay the original work of drainage.
