Siting a pumping station – multi-criteria considerations for reliability and safety Which of the following factors are relevant when selecting the site of a municipal water pumping station?
-
ADistance from potential sources of contamination or pollution
-
BElevation above the river’s highest flood level (HFL)
-
CProvision for future expansion of facilities
-
DProximity to rail/road access for logistics and maintenance
-
EAll the above
Answer
Correct Answer: All the above
Explanation
Introduction / Context:Pumping stations are critical infrastructure. Site selection must balance water quality protection, flood safety, constructability, O&M access, and future growth, ensuring continuous service over decades.
Given Data / Assumptions:
- Urban water-supply context.
- Station near a water source (river/reservoir) exposed to floods and pollution risks.
- Long asset life with expected demand growth.
Concept / Approach:Robust siting addresses public-health protection (adequate offset from pollution), resilience (above HFL with freeboard), expandability (space/utilities), and logistics (transport connectivity for equipment and chemicals). Ignoring any of these can compromise reliability or increase life-cycle costs.
Step-by-Step Solution:Confirm each factor’s relevance → all four are legitimate siting criteria.Therefore, choose “All the above”.
Verification / Alternative check:Design manuals list sanitary control, flood protection, power access, and transportation as standard siting requirements.
Why Other Options Are Wrong:Single-factor choices are incomplete; station siting is inherently multi-criteria.
Common Pitfalls:Focusing solely on hydraulic proximity to source while neglecting flood levels and contamination setbacks.
Final Answer:All the above
