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 (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.
