Kan. Stat. § 65-189f
Also, notwithstanding the provisions of this act, the secretary of health and environment shall adopt rules and regulations which shall, consistent with the purposes of this act, make provision for exceptions to be made in platted areas approved by the board of county commissioners, and filed prior to July 1, 1968, where it is shown that an undue hardship would otherwise result to the developer or owner, and where it is found that the granting of such exceptions would not be unduly harmful to the health and welfare of the area as a whole. When an exception is granted the order granting the same may contain a reasonable time limitation, may require the property owner involved to consent to and connect to a public water and sewer system when available.
