2. OutlineBackground, operation and design of trench drain system.

3. Design advantages of trench drain system.2

4. Learning ObjectivesAt the conclusion of this course, you will be able to:Describe the basic ideas of trench drainage system.List the benefits of trench drainage systems.Compare and contrast the differences between traditional trench drainage systems.Cite case studies and installation examples of trench drain systems.Describe how trench drainage systems can help reduce project costs.3

5. Trench DrainageDrainage is the process of carrying water AWAY from a specific place.

6. The process of drainage has been around for many years.

7. Trench drainage (floor trench) can be referred to as: channel drainage, line drainage, trip drainage and slot drainage.

8. Trench drains are considered to be an open trench with removable grates. Slot drains are a slot in the pavement connected to underground drains and to not have removable grates.

9. Generally a trench is regarded as the completed job in the ground. A channel is an individual modular piece which when added to others makes up the drainage system.4

23. Disadvantages of Catch Basin DrainageUneven appearance.

24. Complex, multiple grades to design and construct.

25. Deeper excavation required due to pipe depths.

26. Higher risk of ponding.

27. Pipes prone to blockage and failure.

28. Maintenance can be difficult and costly since piping is not accessible.
