Question

Which of the following is the limitation of recharge structures?

• A. High evaporation
• B. Clogging
• C. Leakage
• D. Corrosion

Hint:

Major limitation of recharge structures: \[ \boxed{ \text{Sediment deposition} \rightarrow \text{Clogging} \rightarrow \text{Reduced infiltration} } \]

Answer 1

The Correct Option is B

Step 1: Think about a recharge structure over time.
A recharge basin or pit lets surface water soak into the ground through its bed and sides.
Step 2: Consider what builds up on that surface.
Silt, fine sediment, algae, and organic debris carried in the water settle onto the infiltrating surface as it operates season after season.
Step 3: See the consequence.
This buildup blocks the pores of the surface, a problem called clogging, and steadily lowers how much water the structure can let through, which is the main practical limitation compared to evaporation, leakage, or corrosion.
\[ \boxed{\text{Clogging}} \]
