Kan. Stat. § 80-2016
In lieu of the formation of lateral sewer districts, the governing body of such sewage district may construct lateral sewers by the issuance of revenue bonds of such sewage district, whenever there shall have been first presented to such governing body contracts in writing from a sufficient number of property owners along the lines of such proposed lateral sewer, agreeing to pay fixed charges for the use of such sewers for a period of not less than five years, sufficient to pay the principal and interest charges upon such bonds. In case any property owner so contracting shall default in the payment of the amounts provided in such contract, the governing body of such sewer district shall each year, at the time of certifying levies and special assessments to the county clerk, certify the amount such contracting property owner owes on such contract and the same shall be placed upon the tax rolls as a special assessment against the property owned by such contracting party at the time of signing such contract, and served by such sewer system, and be collected in the same manner as other special assessments herein provided.
