18-29-1103.2 Material.
   Storm water traps, when required, shall be of the same material as the piping system to which they are attached.

   Traps for individual conductors shall be the same size as the horizontal drain to which they are connected.
18-29-1103.4 Cleanout.
   An accessible cleanout shall be installed on the building side of the trap.
18-29-1104 Conductors and Connections.
18-29-1104.1 Prohibited use.
   Conductor pipes shall not be used as soil, waste or vent pipes, and soil, waste or vent pipes shall not be used as conductors.
18-29-1104.1.1 District sewer lines.
   In service areas developed after May 30, 2003, where separate sanitary and storm sewers are constructed, drain connections for buildings constructed after May 30, 2003 shall have separate sanitary waste water and storm water connections.
(Added Coun. J. 5-7-03, p. 621, § 1)
18-29-1104.2 Combining storm with sanitary drainage.
   The sanitary and storm drainage systems of a structure shall be entirely separate except where combined sewer systems are utilized. Where a combined sewer is utilized, the building storm drain shall be connected in the same horizontal plane at or downstream of where the building drain exits the building.
18-29-1104.2.1 Separate sewer systems.
   Where feasible, storm water inflows to the existing combined sewer in the public right-of-way shall be directed to a separate storm sewer, should a separate public storm sewer become available. Such re-direction of storm water inflows shall take place within five years of the establishment and availability of a separate public storm sewer, or such reasonable longer period of time as in the judgment of the commissioner of water management is necessary to accomplish such re- direction. This requirement shall not apply to buildings in existence on May 30, 2003, located on private property, that do not have distinct sanitary waste water and storm water connections.
