TECHNOLOGY BAZAAR

Objective

• Participants get to know about a range of useful low-cost

smallholder technologies

Some examples in pictures

Treadle pump 1

• New development, whose

cost are expected to be

around Rs. 1000 (USD 22)

• It lifts water from 25 ft

depth. It can be used to

feed sprinkler or to fill

tanks for drip irrigation

• Some African treadle

pumps cost 75 USD!

Malawi pump

• Is produced in India for export to

Malawi. Wooden pedals are added

locally.

• Cost: approx. 30 USD (packed in

corrugated card board boxes

including spare parts and

transport to Mumbai).

• They have exported around 30’000

pumps in 2 years.

• Why is it not manufactured in

Malawi? They do not have an

adequate metal industry.

Concrete treadle pump

• Has been developed for saline

areas where metal treadle pump

get corroded very quickly.

• It has a PVC sleeve to reduce

friction in washer movement.

• Its disadvantage is its weight of

around 30 kg, which makes it

cumbersome to move it around.

Hoever, farmers who depend on it

for their livelihoods even employ

labour to move it.

• Its cost are around 20 USD.

Treadle pump for surface

water sources

• There are treadle pumps for

tubewell sources and for open

water surfaces (like ponds, open

wells)

• There are different cylinder

diameters (e.g. 5 inches for

water level at 10 ft, 3.5 inches for

water level at 25 ft)

• Its cost are around 20 USD.
