Description

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.  Over a 4-week period, 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 4 weeks, 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.

Each week, a new module will be released, including a recorded lecture, quiz, discussion forum and homework assignment. You will have 7 days to review the lecture and complete the weekly assignments. The instructor will be available by email and phone for questions and comments during the class and will be interacting with students through the weekly discussion forum. The 4-week class will take approximately 6-8 hours to complete over the 4-week period.
