Blacksburg Volunteer Rescue Squad
1300 Progress Street
A properly installed pipe should remain in service for 50 to 100 years with little or no repair. The instructor has documented installation practices for both flexible and rigid pipe at the local and state level. The focus of this class remains on promoting a solid understanding of installation, specifications, design requirements and material differences for pipe systems. Empower your staff with the ability to properly inspect, design, install and accept both flexible and rigid pipe systems.
Join instructor, Walt Catlett for this lively online class and discussion forum that will change the way you think about installing storm drainage pipe. During the day, you will learn more about pipe fundamentals, soil gradation and compaction, excavation, bedding, joining pipe, backfilling and testing of storm drainage pipe. You will learn common crew tasks implemented during the installation and inspection of a properly installed storm drainage pipe. By the end of the day, you will have challenged your current perceptions on pipe installation, identified risks associated with pipe installation and ways to mitigate those risks, learned proper density testing requirements and learned how to recognize proper installation techniques.
