Both systems work the essentially the same way in that they collect water from the roof via the guttering, it passes through a series of filters, and is then stored in a large tank ready for distribution.
. With help of our community on Rainwater Harvesting, we support the development of a more unified global network of national and regional organisations, networks and professionals, working in or interested in rainwater harvesting. The top layer of sand should be cleaned periodically to maintain the recharge rate. Figure 2: Image shows catchment area of the roof top Building in square meters What is Mean Annual Rainfall? Why Sanicon Sustainability Solution Green buildings are considered as elites. It increases the productivity of aquifer. Based on the lithology of the area well assembly is designed with slotted pipe against the shallow and deeper aquifer.
Rain Water Harvesting in India: Need, Methods and other Details
This ismasonry storage tanks by the sides of the building. Surface run-off and roof top water can be diverted to this tank. After selection of suitable site, a trench of 1-2m wide is dug across the breadth of stream down to impermeable bed. Advantages of Rainwater Harvesting 1. Roof top rain water harvesting can be a very effective tool to fight the problem of water shortage particularly in urban areas.

While recharging, entry of floating matter and silt should be restricted because it may clog the recharge structure. The main building of the for 3 to 4 months in a year with high intensity, whichAgricultural College at Coimbatore was constructed results more runoff and soil erosion. Water can be collected from roofs, dams and ponds can be constructed to hold large quantities of so that even on days when little to no rainfall occurs, enough is available to irrigate crops. Or is it more money down the drain?
