The process of collecting and storing rainwater is called water harvesting. Some part of water available on earth is used by plants and human beings. Most of the water is in the form of sea water which cannot be used directly. Due to less rainfall the level of ground water has decreased drastically. Factors like; increase in population, imbalance in rainfall, excessive use of water in industries, wastage of water etc, the amount of drinkable water is decreasing regularly. There are many reasons for the shortage of water. So, it is essential to collect and store rainwater to fulfill our water requirement.
Technique of water harvesting – The rainwater is collected from the rooftop into pits in the ground, through pipes. This water then seeps into the soil to refill the ground water. The water collected in the road side drains must be allowed to go directly into the ground.
