Recently, urged all Indians to take collective
action to conserve water and requested to share traditional methods of water
conservation. The following are few traditional methods of water conservation in
Naula (Uttarakhand): It is a naturally-occurring
water aquifer. It is a stone-lined tank which catches dripping water from
springs and streams. Sculptures of Lord Vishnu or any local deity are usually
carved onto the walls of the Naula to declare it a sacred site and prevent it
from being polluted.
Tankas (Rajasthan): It is a cylindrical paved
underground pit into which rainwater from rooftops, courtyards or artificially
prepared catchments flows.
Surangas (Kerala): It is basically a tunnel dug
through a laterite hillock through which water seeps out and into the tunnel.
Ahar Pynes (Bihar): Ahars are reservoirs with
embankments on three sides that are built at the end of diversion channels.
Pynes are artificial rivulets led off from rivers to collect water in the ahars
for irrigation in the dry months.
Panam Keni (Waynad, Kerala): Wooden cylinders
are made by soaking the stems of toddy palms in water for a long time so that
the core rots away until only the hard outer layer remains. These cylinders, are
then immersed in groundwater springs located in fields and forests.
Zing (Ladakh): They are small tanks that collect
melting glacier water. A network of guiding channels brings water from the
glacier to the tank.
