The following sections of this article are in addition to, or are revisions of, the standard code incorporated by reference in section 15-701:
(a) 101.1 Title. These regulations shall be known as the Private Sewage Disposal Code of De Soto, Kansas hereinafter referred to as “this code”.
(b) 101.2 Scope. Septic tank and effluent absorption systems or other treatment tank and effluent disposal systems shall be permitted where a public sewer is not available to the property served and the minimum lot or parcel area is 1.00 acres. For any lot or parcel that has not been created nor is contained within an approved final plat at the time this standard code is adopted, the minimum 1.00 acre requirement shall not include areas within the boundary of the building lot or parcel that are dedicated for roads, streets, alleys, utility easements, drainage easements, pedestrian easements, landscaping easements, or any other similar encumbrances. Unless specifically approved, the private sewage disposal system of each building shall be entirely separate from and independent of any other building. The use of a common system or a system on a parcel other than the parcel where the structure is located shall be subject to the full requirements of this code as for systems serving public buildings.
Appendix A and B of the International Private Sewage Disposal Code are hereby adopted.
(c) 102.1 General. The provisions of this code shall apply to all matters affecting or relating to structures, as set forth in Section 101. Where, in any specific case, different sections of this code, or the Kansas Department of Health and Environment Bulletin 4-2, specify different materials, methods of construction or other requirements, the most restrictive shall govern.
(d) 102.3.1 Maintenance. All new or replacement Private Sewage Disposal Systems, which may include filters, pumps, timers or mechanical treatment as determined by the Code Official, will require semi-annual or annual maintenance contracts by an approved company or provider. All service contracts must include a clause that the City of De Soto Code Official or his designee will be notified in writing should the contract be terminated. Should any required Service Contract be terminated and a replacement is not provided by the property owner or designee within 30 days, then according to the regulations of the code, the Private Wastewater System will be considered an Unsafe System under 108.7 of the code.
(e) 104.1.1 Licensing. A person licensed as an installer, in Johnson County or in a Kansas county with similar licensing requirements as determined by the Code Official, shall be considered licensed for the purpose of designing and installing conventional and shallow in-ground or conventional mound private wastewater systems that are pumped or gravity fed, as determined by the Code Official. Alternative systems such as aerobic, low pressure pipe drip systems or other permitted alternative systems, must be designed by a licensed Professional Engineer, or by a person licensed as a designer in Johnson County or in a Kansas county with similar licensing requirements as determined by the Code Official.

The City Code requires that an inspection be performed within 30 days after a property is purchased. If major repairs are determined, an additional repair permit may be required before system approval.
(h) 202 General Definitions Re-Sale Inspection. A Re-Sale Inspection is a procedure performed by a City Code Inspector to determine the functional status of a private wastewater system. It involves inspection of the indoor plumbing, the functional components of the system, lot site conditions, and a historical file review. A System Inspection is required at sale of any properties with a private wastewater system in the City of De Soto, with the intent of bringing non-conforming systems up to minimum City Code requirements.
