Rain Water Harvesting

When  the  well's  dry,  we  know  the  worth  of water.” - Benjamin Franklin.

Have you ever imagined a day without water?   

No, we have not and it is hard to imagine. Weall  use  water  for  different  kinds  of  day  to  day activities,  such  as  cleaning,  washing,  bathing, cooking, drinking and other domestic and industrial uses.

Water is a precious, essential and an abiotic  component  of  the  ecosystem.  Today  we  all  are heading  toward  the  scarcity  of  water,  and  this  is mainly because of the lack of water conservation and pollution of water bodies. So, let us not waste a drop

of water and start conserving water for further use.

What is Rainwater Harvesting?

Rainwater harvesting is the simple process or technology used to conserve rainwater by collecting, storing,  conveying  and  purifying  of  rainwater that runs  off  from rooftops,  parks,  roads,  open grounds, etc. for later use. The process of rainwater harvesting involves the collection and the storage of rainwater with the help  of  artificially  designed  systems  that  run  off naturally or man-made catchment areas like the roof

and surface.

How to Harvest the Rainwater?

Rainwater  harvesting  systems  consists  of  the following components: Catchment: Used to collect and store the captured rainwater. Conveyance  system: It  is  used  to  transport  the harvested water from the catchment to the recharge zone.

Flush: It is used to flush out the first spell of rain. Filter: Used for filtering the collected rainwater and removing pollutants. Tanks and the recharge structures: Used to store the filtered water which is ready to use.

We are in the process of installing rain-water harvesting.
