Managing Roadway Drainage Systems

This course will be rescheduled for summer 2023.

Drainage systems are a key asset to maintain. Drainage maintenance is critical for extending the life of pavements, as drainage systems control water flow along maintainable pathways. Routine inspection identifies needed maintenance and lessens the potential for flooding. This includes inspections of shoulders, ditches, pipes, and culverts.

This 2-hour virtual training teaches you to manage drainage systems effectively and efficiently by explaining:

  • What types of drainage assets need to be inspected.
  • What information is collected during an inspection.
  • How to determine if the condition requires a critical, major, or routine maintenance response.
  • What treatments are appropriate, given the type of drainage asset and its current condition.

The training follows the guidelines and structure of the Federal Highway Administration’s Maintenance of Drainage Features for Safety.

Anyone involved in the maintenance of drainage systems or who is responsible for identifying and scheduling drainage maintenance work.
