§ 171.162 LIFT STATIONS.
   (A)   General. A lift station used as a component of an onsite wastewater disposal system shall be watertight and shall be designed to prevent floatation when emptied.
   (B)   Risers. Every lift station shall be equipped with a riser extending a minimum of four inches above grade, and shall be covered with a fitted lid secured by the weight of the lid or other mechanism to prevent unauthorized entry. Final grade shall be sloped away from the riser(s).
   (C)   Pumps and controls. A pump used in an onsite wastewater disposal system shall be specified by its manufacturer as an effluent or sewage pump. Pumps shall be non-automatic, operated by an external switch or control.
      (1)   Pump switches. Pump switches shall be sealed float switches or equivalent. If the pumping volume cannot be accurately set by the tether of an on-off float switch, then a double float switch must be used.
      (2)   Pump controls. Pump controls, if used, shall be operated by float switches or equivalent means. Multiple pumps shall be operated by a control panel.
      (3)   Electrical boxes. Electrical boxes containing wire connections shall be water tight and located outside of the lift station. Electrical wiring entering a lift station shall enter through cast-in-place openings in the riser(s). Wiring shall not be placed in a groove chiseled or cut into the top of the riser(s).
      (4)   Pump and switch placement. Lift station pumps shall be placed at least six inches above the floor of the lift station. Float switches shall be secured to the vertical piping with corrosion resistant straps or ties. All pumps shall be provided with a threaded coupling or other disconnecting fitting, and should be provided with a corrosion resistant rope, strap or other device for removing the pump.
