Developing Groundwater Resources

More information on techniques for the successful and sustainable development of groundwater resources, with particular focus on Africa.

What does groundwater development involve?

Developing groundwater for water supply can involve various different activities, depending on the hydrogeological environment, how much groundwater is needed and what it will be used for. It is usually also important to develop groundwater sources sustainably, so that the groundwater resource is protected and maintained for future supplies.

At its simplest, groundwater flowing naturally from a spring can be directly tapped with very little effort, although protecting that spring, so that the water doesn't become polluted, can be more difficult. In another simple example, where groundwater levels are shallow and the aquifer is easy to dig through (e.g. sand or gravel), hand dug wells can be quite easily constructed to allow groundwater to be abstracted - but again, protecting the groundwater in the well from pollution can be more difficult.

Where the aquifer and/or groundwater levels are deeper, or the aquifer can't be easily dug through by hand, developing groundwater resources is more complicated. It is likely to need some kind of mechanical drilling - either manual drilling, or using a drilling rig.

In areas where the aquifers are all permeable and productive, water boreholes can often be drilled just about anywhere. But in areas with low permeability and/or complex aquifers, or where there are groundwater quality issues, new boreholes and wells must be sited and designed carefully if they are to be successful. To do this, it's important to understand how groundwater exists and behaves in the area.
