Bamboo Treadle Pump


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.

Over 1.7 million have been sold in Bangladesh and elsewhere, generating $1.4 billion in net farmer income in Bangladesh alone .
