Write a short note on water harvesting.
Water harvesting is the practice of collecting and storing rainwater for various purposes, including irrigation, drinking water supply, and household use. It involves capturing rainwater from rooftops, land surfaces, or other areas and directing it to storage tanks or reservoirs.
There are several methods of water harvesting, such as:
Roof Rainwater Harvesting: Collecting rainwater from rooftops using gutters and downspouts, and storing it in tanks or underground cisterns.
Surface Runoff Harvesting: Diverting and capturing rainwater from natural surfaces like roads, driveways, and landscapes, and channeling it into ponds, swales, or storage basins.
Groundwater Recharge: Allowing rainwater to percolate into the soil to replenish groundwater levels, benefiting wells and aquifers.
Water harvesting promotes water conservation, reduces dependency on traditional water sources, and helps mitigate the impact of droughts and water scarcity. It is an environmentally sustainable practice that can be implemented at various scales, from individual households to community-level initiatives, to enhance water security and resilience.
