2. Traditional Methods Of Rain
Water Harvesting

3. INTRODUCTION
• Water forms the lifeline
• The population is increasing rapidly
• All the inhabitants do not have access to safe
water
• There is major problem of supplying adequate
water
• Water Harvesting thus needed

4. Concept and Technology
• A technology used for collecting and storing
rainwater for human use ,using simple
engineered techniques.

5. Methods
• Paar system
• Talab/Bandhis
• Saza Kuwa
• Johad
• Nada/Bandha
• Kunds/Kundis
• Kuis/Beris
• Baoris/Bers
• Tankas/Tanks
• Khadin
• Bengal's Inundation Channel
• Ahar-pynes

6. Paar system
• A common water harvesting practice in the
western Rajasthan
• Rainwater flows from the agar (catchment)
and percolates into the sandy soil
• To acces Rajani pani (percolated water)
kuis or beris are dug in the agor (storage
area)

7. Talab/Bandhis
• Natural - the
ponds (pokhariyan) at Tikamgarh
in the Bundelkhand region.
• Human-made - the lakes in
Udaipur.
• When the water in these
reserviors dries up just a few days
after the monsoon, the pond beds
are cultivated with rice.

8. Saza Kuwas
• An open well with multiple
owners (saza = partner)
• The soil dug out to make the
well pit is used to construct a
huge circular foundation
sloping away from the well.

9. Johad
• Earthen check dams that
capture and conserve
rainwater
• Five rivers that used to go dry
immediately following the
monsoon have now become
perennial, such as the River
Arvari, has come alive.

10. Nada/Bandha
• Found in the Mewar region of
the Thar desert
• A stone check dam,
constructed across a stream or
gully, to capture monsoon
runoff on a stretch of land

11. Kunds/Kundis
• Looks like an upturned cup
nestling in a saucer
• A wire mesh across water-
inlets prevents debris from
falling into the well-pit.
• The sides of the well-pit are
covered with (disinfectant)
lime and ash.
• Most pits have a dome-shaped
cover, or at least a lid, to
protect the water

12. Kuis / Beris
• Found in western Rajasthan,
10-12 m deep pits dug near
tanks to collect the seepage
• The mouth of the pit is usually
made very narrow to prevent
the collected water from
evaporating
• Used to harvest rainwater in
areas with meagre rainfall.

13. Baoris / Bers
• Baoris or bers are community
wells used mainly for drinking
• Can hold water for a long time
because of almost negligible
water evaporation.

14. Khadin
• A khadin, also called a dhora,
is an ingenious construction
designed to harvest surface
runoff water for agriculture
• Based on the principle of
harvesting rainwater on
farmland and subsequent use
of this water-saturated land
for crop production.

15. Ahar pines
• A catchment basin embanked
on three sides, the 'fourth' side
being the natural gradient of
the land itself
• Pynes are articifial channels
constructed to utilise river
water in agricultural fields.
•
The ahar-pyne system received
a death-blow under the
nineteenth-century British
colonial regime.
