Benefits of water harvesting are: It provides drinking water. First of all, harvesting rainwater allows us to better utilize an energy resource. Reduces the cost for pumping of ground water 3. Artificial recharge is the planned, human activity of augmenting the amount of groundwater available through works designed to increase the natural replenishment or percolation of surface waters into the groundwater aquifers, resulting in a corresponding increase in the amount of groundwater available for abstraction. What are the advantages of rain water harvesting. It is an excellent way to manage urban water systems that tend to be erratic, especially in cities that experience . Engineering and Geological Considerations Ground water serves the great majority of people who live in rural areas and have a water-supply system of one type or another.
