Difficulty: Easy
Choose an option
-
ADigging a well for water
-
BConstruction of dams
-
CConstruction of canals
-
DEntire arrangement from source to distribution
-
ENone of these
Answer
Correct Answer: Entire arrangement from source to distribution
Explanation
Introduction / Context:A water supply system is not limited to one activity like digging wells or building canals. It is a complete arrangement from sourcing water to its final distribution to consumers.
Given Data / Assumptions:
- Water must be collected, transported, treated, stored, and distributed.
- System scope includes all engineering works related to supply.
Concept / Approach:The water supply system is a holistic infrastructure chain ensuring safe and continuous delivery of potable water.
Step-by-Step Solution:
1. Water is collected from sources (wells, rivers, dams).2. Conveyed through canals or pipes to treatment plants.3. Treated to meet potable standards.4. Stored in service reservoirs.5. Distributed through mains and submains to users.Verification / Alternative check:This is consistent with IS:1172 and CPHEEO manuals defining the scope of water supply systems.
Why Other Options Are Wrong:
- Digging a well, dams, canals: These are components, not the entire system.
- None of these: Incorrect since one option clearly represents the whole scope.
Common Pitfalls:
- Confusing individual components as the whole system.
- Neglecting treatment and distribution as part of the system.
Final Answer:Entire arrangement from source to distribution
