Water harvesting is need of time because water level in ground is going below. In Bangalore , we don't get water at 2000 feet. IN future, if we don't harvest there will be huge scarcity of water.

read more Areas on the planet that have long faced water shortage .we are able to combat this problem by harvesting what little rain water we receive. Rainwater harvesting: It 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 (well, shaft, or borehole), 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. read less

Water harvesting is the need of the hour because due to excessive population growth and pollution our fresh water resources are depleting as well the water table, which is under ground. Rain water harvesting helps us in using our available water sources sustainably and in conserving them.

read more we have scarce water resource, so we should make use of that in the most efficient way by recycling waste water and using it for productive purposes.Since water is a boon of nature we should make use of the rain water by implementing rain water harvesting throughout the nation and should monitor that excess rain water goes to the wells, tanks, ponds directly, and assure that only a small amount directly goes to the storm water drains.It should be seen that sewage water goes to the sewage drain and rain water if in excess goes to the storm water drain alone.Owing to all of this measures which we have not done in many cities fully, it becomes necessary to drill the wells and make it more deep to accumulate the water coming out of the rain harvesting pipe, so that it can be used in future in times of drought without adequate rains and monsoon. read less
