Digging a new well with the tubewell technology promoted by EnterpriseWorks in Niger. Tubewell innovation cuts costs. This innovation has reduced the cost of tubewells by a factor of six, while making it easier for local well drillers to obtain the casing material. Other aspects of research are ongoing, as different soil conditions are encountered that require modifications to the drilling tools or installation practices. For example, different diameters and different thicknesses of pipe are now being used for wrapped screens to reduce their costs and increase their durability.
Researchers seek low-cost way to reduce water infiltration.
Plastic sheeting is currently being field tested by local gardeners to evaluate its effectiveness at reducing infiltration losses. However, high-quality plastic sheeting that resists high temperatures and extreme exposure to sunlight is both relatively expensive and difficult to obtain locally. For this reason, the project plans to research lower-cost materials that are available locally, such as traditional clay blocks. Simple drip irrigation systems will be tested as well, especially for sites where the water table is relatively deeper and pumping costs are higher. Exports hold promise for the future.
