Which one of the following is NOT a layout of tile drain?

• A. French Drain System
• B. Herringbone System
• C. Grid Iron System
• D. Intercepting Drain System

Answer 1

The Correct Option is A

Step 1: Understanding Tile Drainage Systems
Tile drainage involves subsurface pipes to remove excess water. Common layouts: - Herringbone: V-shaped branches converging into a main drain. - Grid Iron: Parallel drains leading to a collector. - Intercepting Drain: Blocks lateral water movement.
Step 2: Why French Drain is Incorrect?
French drains use gravel-filled trenches, not tile pipes.
Step 3: Conclusion
French drains are not classified as tile drain layouts.
