Rainwater harvesting is the accumulation and deposition of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places the water collected is redirected to a deep pit, a reservoir with percolation, or collected from dew or fog with nets or other tools. Its uses include water for gardens,livestock, irrigation, domestic use with proper treatment, and indoor heating for houses etc. The harvested water can also be used as drinking water, longer-term storage and for other purposes such as groundwater recharge.
Talab/ Bandhis
Talabs were reservoirs. They could be natural, such as the ponds at Tikamgarh in the Bundelkhand region or could be man-made, such as the lakes in Udaipur. A reservoir area of less than five bighas was called a talai; a medium sized lake was called a bandhi or talab; bigger lakes were called sagar or samand. The pokhariyan served the purpose of irrigation and drinking. When the water in these reservoirs dried up, the pond beds were used for cultivation.
Johads
Johads, in Rajasthan, were small earthen check dams built to capture and conserve rainwater, thus improving percolation and recharging ground water1.
Baoris / Bers
Baoris or bers were community wells, found in Rajasthan, that were used mainly for drinking. Most of them are very old and were built bybanjaras for their drinking water needs. They could hold water for a long time because of almost negligible water evaporation.
