Why Rainwater Harvesting is the future of water conservation?
“When the well’s dry, we know the worth of water.” – Benjamin Franklin
Did you know our country receives about 4000 billion cubic meters of rainwater from the sky? And out of which only 25% is actually used, and the rest runs off into the sea and evaporates. This quantum remains more or less relentless, though there are regional differences subject to local landforms and rock structures.
Though government has been doing all possible ways to optimize the use of rain water, but we as the proud citizens of the country should do our part of good to save water for our future generations. And the best way to move forward is to choose Rainwater Harvesting.
Rainwater harvesting is typically referred to as the gathering, or collecting and storing, of rainwater. Rainwater harvesting can be used to provide drinking water, water for livestock, and water for irrigation or to refill aquifers in a process called groundwater recharge. Rainwater collected from the roofs of houses, tents and local institutions, or from purposefully prepared areas of ground, can make a valuable contribution to drinking water.
There are a number of types of systems that can be employed to harvest rainwater ranging from simple to the complex industrial systems. Usually, rainwater is either harvested from the ground or from a roof. The rate at which water can be collected from either system depends on the overall area of the system, its efficiency, and the frequency of rainfall.
There are several advantages associated with Rainwater Harvesting such as:
- Helps you cut down on your water bills (particularly in cities where people have to buy water)
- Reduces the need of the municipal water supply
- Ensures efficient use of a valuable resource
- Eliminates soil erosion
- Prevents the contamination of ground water
Therefore, it can be easily ascertained from the above points that rainwater harvesting has become the need of the hour. Unless we get rainwater harvesting as a movement we cannot think of having a happy future and for that people have to be inspired to make this a habit.
In our next post, we will discuss about various types of Rainwater Harvesting.
