§ 171.147 SEWAGE DRAINAGE SYSTEM.
   (A)   Plumbing fixtures shall be drained to a sewage drainage system and such system shall be connected to a public sewer or to an adequate and approved system of sewage disposal.
   (B)   Where a public sewer is not available, a system shall be provided to receive and dispose of sewage without health hazard or nuisance.
   (C)   Sewage or other waste, which may be deleterious to surface or subsurface waters, shall not be discharged into the ground or into a waterway unless it has first been rendered harmless through subjection to treatment in conformity with generally accepted standards.
   (D)   Substances which will clog the pipes, produce explosive mixtures, destroy the pipes or their joints or interfere unduly with the sewage disposal process shall not be discharged into the building drainage system unless it is provided with approved devices suitable for intercepting such substances.
   (E)   Each fixture directly connected to the sewage drainage system shall be equipped with a water seal trap.
   (F)   Adequate cleanouts shall be provided and maintained so that the pipes may be readily cleaned.
   (G)   The drainage system and its attendant vent piping shall be maintained so as to provide adequate circulation of air in all pipes in order that siphonage, aspiration or pressure will not cause a loss of trap seal under ordinary conditions of use.
   (H)   Each vent terminal to the outer air shall be installed and maintained so as to minimize the possibilities of clogging, frost closure, the return of foul air to the building or the creation of a nuisance to adjacent premises.
   (I)   Drains provided for fixtures, devices, appliances or apparatus containing food, water, sterile goods or similar materials, shall be equipped with air breaks, adequate to prevent contamination of such contents from any possible backup of sewage through the direct or indirect drainage piping.
