Question

The layout of distribution system in which water flows towards outer Periphery is:

• A. Ring system
• B. Dead end system
• C. Grid-iron system
• D. Radial system

Answer 1

The correct option is D Radial system

1. Radial system
(a) A very big area is divided into several zones and at the center of each zone, a distribution reservoir is kept.
(b) In this system, the central reservoir flows the water towards the Outer Periphery.
(c) This method gives a higher service head and efficient water distribution.
Dead end system
(a) The system has one main pipe from which several sub mains bifurcate and from each sub mains, several branched pipes separate which are known as laterals.
(b) Such type of distribution system is followed for old towns where the houses come up in a very unplanned way.

Ring system
(a) The system is also known as a circular system
(b) The system consists of the main pipe all around the area
4. Grid iron system
(a) In this system, one main pipe runs through the center, and branches and laterals run in a grid pattern that is interconnected.
(b) Since the main, branches, and laterals are interconnected hence dead ends are eliminated and water reaches a different location through more than one route.
