RAINWATER HARVESTING WHAT IS RAINWATER HARVESTING? Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden‚ water for livestock‚ water for irrigation‚ and indoor heating for houses etc. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used as drinking water as well as for storage and other purpose like irrigation. ADVANTAGES Rainwater harvesting

For example‚ the earth is running out of fresh water. In the Ogallala Aquifer in the Midwestern U.S.‚ research shows that we’ve tapped underground water sources pretty heavily in this particular place; Its water level has dropped more than 150 feet‚ leaving farmers with no water for their crops (NG).

At a research site in the southern part of Bangladesh‚ scientists calculated that irrigation pumping‚ which began in the last several decades‚ has dramatically altered groundwater flow through the aquifer. They show that the resulting changes to the chemistry of the groundwater have the potential to either increase or decrease arsenic levels‚ in a paper written by an MIT-led team of scientists in the Nov. 22 issue of Science.
