Question

The component of the rainwater harvesting system is
A. Conduits
B. Dam
C. Lake
D. None of the above

Answer 1

Hint: Rainwater harvesting is the collection and storage of rainwater for reuse on-site, instead of allowing it to escape. These stored waters are used for various purposes like gardening, irrigation, etc.
The tactic applied is executed by the assistance of pipelines or drains to hold rainwater from one part to a different within the harvesting system.

Complete answer: Rainwater harvesting (RWH) is the collection and storage of rain, instead of allowing it to escape.
1. Rainwater is collected from a roof-like surface and redirected to a cistern, deep pit (well or borehole like a shaft), aquifer, or a reservoir by allowing percolation of the water.
2. Dew and fog can be collected as well with nets or other tools. Its uses include watering gardens, irrigating fields, for domestic use, etc.
3. The harvested water also can be stored for longer durations.
4. Rainwater pipes/conduits carry water from the rooftop to the bottom. These pipes need to be connected and drawn to the specified location by providing sufficient slope in proper structured order such that the water flows along the direction of gravity and no water gets trapped within the pipes.
Alternatively, the pipes also can be laid underground.

So, the correct answer is option A. Conduits.

Note: Rainwater harvesting is one of the oldest and economical methods of water storage among other complex and challenging water storage methods. Due to this reason in many countries, the government has financed the construction of rainwater harvesting systems in schools, hospitals, and even households.
