Rainwater harvesting is the process of collecting and storing rainwater for later use. It helps in conserving water, reducing dependency on groundwater, and mitigating urban flooding.
Rooftop rainwater harvesting involves collecting rainwater from roofs and storing it in tanks. It's a simple and effective method suitable for individual homes and buildings.
Surface runoff harvesting collects rainwater from open spaces like roads and gardens. This water can be directed into reservoirs, ponds, or underground storage systems for later use.
Check dams and nala bunds are small barriers built across streams and rivers to slow down water flow. They help in recharging groundwater and preventing soil erosion.
Percolation pits are deep holes filled with gravel and sand. They allow rainwater to seep into the ground, replenishing groundwater levels and improving soil moisture.
Rainwater harvesting reduces water bills, decreases flood risks, and lessens soil erosion. It ensures a sustainable water supply, especially in drought-prone areas.
