What is water harvesting technology

The crisis is of drought are non-availability of consumptive water and also non-consumptive water i.e. water we need for domestic, agricultural and industrial use and the water in dam-reservoir is also made available for hydropower generation.

If the rains are late or inadequate, the surface runoff, the rate of infiltration is reduced due to which there is a shortage of surface water and groundwater to create severe drought conditions.

To control the end product, it is necessary to harvest the water [ save it for a non-rainy day or non-rainy year] the technique used to increase the recharge of groundwater by capturing the storing rainwater is known as rainwater harvesting.

Rainwater harvesting is a proves by which the groundwater reservoirs is enhanced at a note exceeding that obtaining under natural conditions or replenishment.
