Enlargement of boundaries; petition; special assessments

After the establishment of any sewage district or lateral sewer district, as herein provided, and subject to the provisions of K.S.A. 19-270, the boundaries of any such district may be enlarged by the filing with the governing body thereof of a petition signed by a majority of the resident property owners in the territory proposed to be added to such district. Whenever such district is enlarged, the governing body shall levy a special assessment against all the property added thereto, in an amount equal to the proportionate cost of all improvements theretofore made in such original district necessarily usable by such additional territory, or the bonds issued therefor, together with the special assessments for the additional improvements made in such territory so added by enlargement in the same manner as if such additional territory had been a part of such district when originally created. Such sums as may be received by such enlargement and assessment in favor of the original district shall be used to retire bonds issued for the construction of the system in the original sewer district.
