(a) Whenever the total special assessment on any property for storm or sanitary sewers has been paid, the property shall not be transferred to another district and thereby be made liable for special assessments for storm or sanitary sewers in another district. The property may be included in a joint sewer district and may be assessed the costs incurred for the building of sewers which serves all the property within the joint sewer district.

(b) After a part but not all of the sewers which will ultimately serve all the property in a sewer district are constructed and upon petition of any landowner in the district who desires to have a sewer built to serve the petitioner’s land, the governing body of the district may design, plan and build the sewers and apportion and assess the cost thereof in the manner provided by Kan. Stat. Ann. § 19-27a07.

(c) When additional sewers are constructed, after a part but not all of the sewers have been constructed, in any lateral sewer district, the cost of the construction of additional sewers shall be charged to the property served by the sewers and none other.
