Water Distribution Systems MCQ with answer and solution

Concept

Water distribution system layout for irregular towns

Formula

NONE

Step-by-step solution

1. Irregularly growing towns expand without planned road layouts or defined grid patterns. 2. A dead-end distribution system allows easy extension of branch pipes along randomly developed roads. 3. Therefore, the dead-end system is most suitable for an irregular developing town or city. Answer: A

Explanation

The dead-end system, also known as the tree system, features a central main pipe with branch lines running without forming interconnected loops. It is simple to design and extend incrementally, making it well-suited for old or irregularly expanding towns that lack planned road layouts.

Why the other options are wrong

B) The grid-iron system is suitable for well-planned cities with rectangular road patterns. C) The circular or ring system is suitable for well-planned towns with circular main roads. D) The radial system is suitable for cities with radial road patterns where water is pumped from central high-level reservoirs.

Shortcut

Irregular or unplanned towns use the Dead-end system.

Common mistake

Confusing the dead-end system suitable for unplanned towns with the grid-iron system suitable for planned cities.
