Question

What is roof top rainwater harvesting ?

Hint:

Think of rain falling on a roof being collected and stored or sent into the ground instead of going waste.

Answer 1

Step 1: Definition:
Roof top rainwater harvesting is a method of collecting and storing rain that falls on the roof of a building.
The roof acts as the catchment area.

Step 2: How it works:
Rain falling on the roof flows into gutters and down pipes.
The water then passes through a filter to remove dust and leaves.
It is then stored in a tank for use, or it is sent into the ground through a recharge pit or well.

Step 3: Why it is useful:
It saves water for use in the dry months.
It raises the ground water level and cuts the load on the water supply.
It also helps to reduce water logging on roads.

Final Answer:
Roof top rainwater harvesting means collecting rain from roofs and storing it or recharging ground water.
