meters i.e. 210 million cubic meters. By natural process, 10% of this runoff
will meet the groundwater which works out to be only 21 mcm/annum;
whereas, the technique given in this paper would assimilate 80% of the
total runoff to groundwater which is estimated as 168 mcm/annum. This
example clearly shows that 8-10 times water will be additionally stored in
under ground reservoir.
8. Conclusion
The rainwater-harvesting technique presented in this paper is less expensive
than any other techniques of artificial recharge, if implemented at the time
of road construction itself. The innovatively designed structures are simple,
easy to construct, operate, and maintain. These techniques may be initially
taken up as pilot project in some priority sectors. It may turn out to be
lifeline in surviving domestic water requirement during summer/draught in
a matter of year or two. Besides, it may sustain water availability till the
time long-term projects like interlinking of rivers desalination of sea water,
etc. sees the light of the day.
