⭕ A. Dead end system
⭕ B. Grid iron system
⭕ C. Radial system
⭕ D. Ring system
📚 Explanation:
For an irregularly growing town, the most suitable water distribution layout is the Dead end system (also called tree system).
🔹 It is simple in design and easy to operate.
🔹 Construction cost is low, making it ideal for uneven and unplanned growth areas.
🔹 Water mains branch out like a tree structure, matching irregular street patterns.
Why not others?
- Grid iron is suitable for well-planned cities.
- Radial is used where water is supplied from a central point.
- Ring system suits circular city layouts.
