What is the main purpose of rainwater harvesting class 10?
The main purpose of rain water harvesting is to make rainwater percolate under the ground so as to recharge ground water.
Rainwater harvesting is the process of collecting rainwater from surfaces on which rain falls, filtering it and storing it for multiple uses. Rainwater harvesting puts the supply of water back to normal levels. It is the collection and storage of water from surfaces that rain has fallen upon.
What is water harvesting and its techniques?
Water harvesting techniques gather water from an area termed the ‘catchment area’ and channel it to the cropping area or wherever it is required. Conservation techniques conserve water within the biomass and the soil by reducing run-off and keeping the water where it falls, as much as possible.
Rainwater harvesting puts the supply of water back to normal levels. It is the collection and storage of water from surfaces that rain has fallen upon. Rainwater harvesting is an innovative technique utilized to harvest rainwater from roofs and other above surfaces to be stored for later use.
