Question

Identify the reason. Why water in the wells dries up fastly?

• A. Because the population increses
• B. Because people dont use water harvesting techniques
• C. Both a and b
• D. None of these

Answer 1

Answer: (C)

Both a and b

• In cases where the area of influence of a well extends to a nearby stream or lake, there is a reversal in the flow direction and the water body begins to lose water to the well by induced recharge. Streams, wetlands, and lakes can dry up completely under sustained conditions of induced recharge.
  
• Rainwater harvesting provides an independent water supply during regional water restrictions and in developed countries is often used to supplement the main supply.
  
• It provides water when there is a drought, can help mitigate flooding of low-lying areas, and reduces demand on wells which may enable groundwater levels to be sustained.
  
• It also helps in the availability of potable water as rainwater is substantially free of salinity and other salts.
  
• The increase in population also needs more use of water.
  
• Due to all these reasons water in the wells dries up fastly.
