Trench Drains and Hopper Bottom Pits are part of a good wash pad design and are an essential component of an effective wash and water recovery system.  Common sense recommendations with most stationary wash pad designs include:

  • An adequately sized Wash Pad -- Good design allows for a minimum of 10' clearance all around the largest vehicle to be washed on the wash pad.
  • An Equipment Pad should also be adequately sized to allow for the proper layout of all wash and water recovery equipment and should be elevated off the wash pad 4-6" to keep equipment out of standing water.
  • To facilitate dirt, silt and debris "drop-out" a Trench Drain is highly recommended.  Most applications require the Trench Drain to be no more that 6-12" deep and 12-18" wide.  Angle Iron Dams positioned 5-6' apart and located on the floor of the trench drain are recommended to facilitate dirt and silt drop out in the trench.
  • A Hopper Bottom Pit is also recommended in the water drainage system.  The Hopper Bottom Pit is used as part of a Sludge Removal System to eliminate sludge from the pit without costly pumping out.
  • Depending on dirt, oil and grease content in the water, more than one Hopper Bottom Pit or a multi-compartment clarifier may be required.
