Lets ACT collectively NOW before its too late…
India is blessed with abundant rainfall in large parts of the country.
– We are presented with an opportunity to store this free and depleting resource, by creating an eco system that requires negligible operational cost or maintenance
– While other nations are forced to spend thousands of crores, thanks to our abundant rainfall, within a fraction of that cost we can replicate a ground water aquifer replenishment system that will be our “water deposit” for years to come.
– This eco system needs to be looked at as an investment rather than an expense, before it is too late.
Why RAIN WATER HARVESTING IS CRITICAL TODAY
Since our Urban cities today can’t increase dams or catchment zones indefinitely, Desalination becomes the only viable alternative, in the absence of any other source.
However 500 scientifically selected recharge wells a year could deliver a fifth of the water a 200MLD desalination plant could provide, at a fraction of the cost.
Advantages:
- Perennial source for generations to come.
- Negligible comparative cost for creation
- Near Zero operational cost
- Zero piping infrastructure needed for the end user.
- Augments the earths ground water table indefinitely.
2) PREVENTS SALINE WATER FROM INFILTRATING THE FRESH GROUND WATER TABLE
The law of physics dictates that water from a high pressure area will flow naturally into water at a low pressure area.
As the ground water table decreases, and sea levels rise, the pressure difference between the sea water and ground water table will increase, allowing sea water to permeate and permanently destroy the underground fresh water table.
It is imperative in our costal cities, to protect and save the underground water table, by ensuring that this barrier zone between the fresh water and sea water is sustained.
This can only be done if the fresh underground water level is replenished and maintains a positive level through recharge wells.
More critical with the glaciers melting and the sea level rising. The ground water in our coastal cities are at a very high risk of becoming saline permanently.
3) PREVENT FLOODING
Strategically placed recharge wells will not just help fill the aquifers, but reduce the impact of the rivers that discharge into the sea from overflowing.
