Warehouse Drainage

Trench Drain Systems

Drainage for warehouses can serve a variety of purposes. Outside of the building, large areas of paved surface will need to appropriate drainage to handle the diversion of rainfall. Drainage inside the warehouse depends upon the purpose of the building. Vehicles and other equipment being stored may be washed down from time to time or have weather runoff from snow or rain that needs to be channeled out of the building. Buildings used for storage of fluids such as chemicals or beverages, drainage can simply be used for risk management in the event that there is a failure of storage containers.

Parking lots and surrounding paved areas need to be considered as well since the solid surface forces rainwater to be diverted rather than naturally soak into the ground.

Trench Drain Systems offers an extensive line of trench drain channels, grates and catch basins.

  • Exclusive product lines manufactured by TDS 
  • Flow rate range of 30 – 6,700 Gallons Per Minute 
  • Grates in all load ratings for heavy traffic of loading docks, warehouses and manufacturing facilities 
  • Drain experts to provide quotes customized to the job specs 
  • Pre-sloped and neutral channels 
  • Material options for grates to withstand chemicals and weathering

3 Considerations

Heavy Duty

Ensure that grates are strong enough to handle areas that may have heavy equipment traffic. Ask our experts to help you determine the right rating.

Location, Location, Location

Ensure drainage has either natural soaking soils or compensates for pavement that will have additional rainfall to be diverted.

New Neighbors

Is there potential for new structures or paved surfaces to be built nearby which may overpower your drainage system?
