Kan. Stat. § 13-1013
The governing body may provide for a system of sewerage and drainage for the city, or any part thereof, and build and construct sewers and drains for the city, or any part thereof. Such sewers shall be constructed by districts created by ordinance. Such districts shall be in three classes, intercepting, main and lateral. Whenever in the judgment of the governing body it is necessary in order to properly handle the sewage or drainage of a city, that two or more main sewers, constructed as hereinafter provided, be connected, then the governing body shall have power to create an intercepting sewer district and build and construct an intercepting sewer. The district for such sewer shall be created by ordinance, and shall embrace all that part of the city which will be benefited by such intercepting sewer.
When it is necessary that any part of the city have a system of sewerage or drains, then the governing body shall have power to create a main sewer district and shall have power to build and construct a main sewer, which main sewer shall be a trunk-line sewer to which lateral sewers, constructed as hereinafter provided, may be connected whenever the same are constructed. Whenever it is necessary that any part of a main sewer district have a lateral sewer then the governing body shall have power to create a lateral sewer district and to build and construct a lateral sewer. Intercepting, main and lateral sewer districts shall be created and defined by ordinance and the cost of all such sewers, intercepting, main and lateral, shall be assessed against all lots and pieces of land in the districts as created and such special assessment shall be levied by the city and certified by the city clerk to the county clerk to be placed on the tax rolls for collection, subject to the same penalties and collected in like manner as other taxes.
The procedure used by the city in determining the valuation to be placed on lots and pieces of land in sewer districts, for the purpose of special assessments to pay for the cost of constructing sewers, shall be the same as provided for determining the valuation of lots and pieces of land for the purpose of special assessments to pay for the cost of paving streets in cities of the first class: Provided, however, That no property which has paid its full proportion for a main sewer shall be transferred to any other main sewer district and made liable for the construction of a main sewer therein, nor shall any property which has paid its full proportion for a lateral sewer be transferred to any other lateral sewer district and made liable for the construction of a lateral sewer herein.
The governing body shall have power to rebuild, reconstruct or enlarge any sewer now constructed, or hereafter constructed, whenever in the judgment of the governing body such sewer is inadequate, defective or worn out, and the cost of such rebuilding, reconstruction or enlargement shall be levied on the property benefited by such rebuilding, reconstructing or enlargement in the manner hereinbefore provided in the construction of new sewers.
