Section 4: Technology of Rainwater Catchment Systems
Technologies for Enhancing Ground Water Recharge
CSIR, New Delhi, India
In countries like India, with an ever-increasing demand for
water, the importance of rainwater harvesting and groundwater recharge cannot
be overemphasized. With this background in view, the laboratories of the
Council of Scientific & Industrial Research have developed and demonstrated
various technologies for the enhancement of recharge through various means.
These are the use of injection bore holes in hard rock, recharge through tanks
wells, siphon recharge, enhancement of run off through treatment of catchment
with polyamine material use of chemical for control of evaporation and also for
stabilizing and sealing of soil through hydrophobic chemicals, etc. This paper
attempts to consolidate the experiences gathered in respect of the case studies
in various rainfall regions with different soil characteristics.
