Water distribution system layout for rectangular roads
Formula
NONE
Step-by-step solution
1. In towns with a planned rectangular road grid, water mains and sub-mains are laid out in a grid pattern. 2. The grid iron system allows water to flow to any given point from multiple directions without dead ends. 3. Therefore, the grid iron system is the most suitable layout for rectangular road networks. Answer: B
Explanation
The grid iron system consists of main lines, branch lines, and sub-mains laid out in an interconnected rectangular grid pattern. This layout naturally aligns with municipal planning in towns designed with grid-patterned or rectangular road networks. It eliminates dead ends and allows water to reach any consumption point from multiple directions.
Why the other options are wrong
A) The dead end system is suited for old, irregularly planned cities. C) The ring system is suited for circular or planned areas where main supply pipes surround the zone. D) The radial system is suited for cities with radial road patterns where water is distributed from central high points.
Shortcut
Rectangular road patterns use the Grid Iron distribution system.
Common mistake
Confusing the grid iron system with the dead-end or ring systems for rectangular street layouts.
Correct answer: B) Grid iron system
