Product Description

iDE treadle pump is a foot-operated device to create suction to pump water from shallow aquifers or surface water bodies. It can be attached to a flexible hose, and lift water at shallow depths from any source such as pond, tank, canal, or catchment basin or from tube wells.

It was developed in 1979 by a team working with the Rangpur Dinajpur Rural Service (RDRS), an NGO working in northwest Bangladesh. International Development Enterprises (iDE) facilitates the formation of national and regional networks of suppliers, dealers, and installers.

Design Specifications

The pump is made mostly of metal and consists of two cylinders (or barrels) usually 3.5 inches (8.9 cm) in diameter, connected to a suction pipe at the base, and with an outlet spout at the top. The operating mechanism consists of bamboo or metal foot pedals fitted to a bamboo superstructure, and includes a framework that the operator can hold onto for support. The pump is installed on a bamboo or PVC-lined tubewell.

Product Schematics

Technical Support

IDE trains technicians and provides technical assistance if needed.

Replacement Components

Locally available at hardware stores.

Lifecycle

The average life of treadle pumps ranges from 1 to 7 years as seen in the table.

18-gauge 3-5 years
20-gauge 1-2 years
 

Manufacturer Specified Performance Parameters

It is claimed that the treadle pump could raise the annual net household income by US$50-$500, on the average. It is said that the average crop yields on “priority plots” tend to be much higher than yields obtained by farmers using diesel pumps or other irrigation devices.

Vetted Performance Status

The performance of the iDE treadle pump was tested by Rangpur Dinajpur Rural Services in 1991, who found it to be "a cheap, efficient manual irrigation pump which is simple to maintain and repair". Studies evaluated by the International Water Management Institute show treadle pump owners have better boro rice, potato and green vegetables yields than pumpless small folders and sometimes even surpassing diesel pump owners.  

Safety

First time users can experience aches and pains when operating the product.

Complementary Technical Systems

IDE offers promotion of pump dealers, training and technical assistance, and access to new products.

Compliance with regulations

IDE carries out quality inspections, stamping the pumps with a brand name, and selling them to a network of rural dealers.

Other Information

The pump is said to have a benefit-cost ratio of 5, an internal rate of return of 100 percent, and a payback period of one year. Similar treadle pumps, commercialized by Enterprise Works (EW) in West Africa, have reported gender related problems in terms of adopting this technology, suggesting that treadle pumps may not be culturally appropriate or simply will not be used in some regions.
