Bamboo Treadle pump is a good rural innovation for the poor  formers made by the Gunnar Barnes of Rangpur/ Dinajpur Rural Service and International Development Enterprises (IDE) Nepal.

Poor formers of these areas generally have limited resources of energy, So they found a way to fulfill their requirement using  Bamboo Treadle pump.

The pump, which consists of two metal cylinders with pistons that are operated by a natural walking motion on two treadles, can be manufactured locally by metalworking shops. Over 1.7 million have been sold in Bangladesh and elsewhere, generating $1.4 billion in net farmer income in Bangladesh alone .
