Parking Structure Drainage

Parking structures displace a large amount of rainfall that is not able to soak naturally into soil. The more surface area used, the more rainfall that needs to be redirected. Drainage systems for these structures remove storm water quickly and efficiently so that there is minimal impact on vehicle and pedestrian traffic as well as the surrounding environment.

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

  • Exclusive product lines manufactured by TDS 
  • Grates in all load ratings for high traffic parking structures 
  • Pre-sloped and neutral channels to divert runoff efficiently 
  • Flow rate range of 30 – 6,700 Gallons Per Minute 
  • Multiple innovative and versatile designs for easy installation 
  • Numerous materials for grates to withstand harsh chemicals

3 Considerations

Regional Weather

Consider how much rain could potentially fall in the area including times of extraordinary flooding. Contact our experts to help you plan your project.

Keeping it Legal

Ensure that you are following any local, state or federal laws that may affect your project.

Giving Directions

Ensure that there is a clear plan as to where the rainfall will be directed to avoid potential erosion.
