Rainwater harvesting (RWH) is the collection and storage of rain water, rathwing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer or a reservoir with percolation, so that it seeps down and restores the ground water. Rainwater harvesting differs from storm water harvesting as the runoff is typically collected from roofs and other surfaces for storage and subsequent reuse.  Its uses include watering gardens, livestock, in-situ for soil moisture build up, irrigation and domestic use with proper treatment. The harvested water can also be committed to longer-term storage or groundwater recharge. Rainwater harvesting and reuse is a regular activity of Greenfield Eco Solutions since its inception. A fewof our activities related to the rainwater harvesting during the last 10 years are at Water Resource Department, Khajuraho Madhya Pradesh, National Mineral Development Corporation's Diamond Mines at Panna, and Water Wisdom Foundation, Udaipur.
