BEFORE Uncontrolled Drop
  • Solids separated
  • Wall of manhole and bench erosion
  • Solids and liquids not carried away
  • H2S emissions high
  • Maintenance high
  • Access difficult (multiple inlets must be plugged for work or access to areas below)
AFTER Controlled drop with RELINER Inside Drop Bowl
  • Solids and liquids remain together
  • Easy inspection and cleaning from above
  • Erosion of structure eliminated (walls and benches)
  • H2S emissions reduced
  • Reduced maintenance
  • Service from street eliminates confined space entry
  • Use in wet wells to reduce pump cavitation
  • Several sizes in stock
  • Custom sizes available
  • Eliminate troublesome outside drops
    Now, a compact, simple, cost effective solution for containing the flow of Inside Drops in Manholes:

    The Patented RELINER Inside Drop Bowl simply attaches to the manhole wall with stainless expansion bolts and special fully adjustable stainless steel pipe clamping supports (SS Adjustable PIpe Brackets) 

    The low profile bowl is shaped to provide full access and inspection from above without reducing access to areas below.

    It is ideal for new service installations, micro-tunneled services, wet wells, as well as existing and failed outside drops—and when used in combination with the RELINER Modular Invert System, it provides true fluid containment integrity.

    A Force Line Hood is available for force line inlets.

     

    All sizes are for retrofit or new construction—fabricated in marine grade fiberglass and finished in bright white gel coat.

    Drop Bowls are ideal for wet wells. They help prevent pump cavitation.

    The Drop Bowl is available in several sizes in round and flat configuration:

    "A" Drop Bowls: The "A4" bowl will service up through full 6" inlets. The "A6" bowl will service up through full 8" inlets. Can be used for 10" inlet moderate flows. A Force Line Hood is available to fit the "A" Bowl.
