Building a well in Africa: steps, costs and testimonies

People often picture a well as simply a hole dug until you hit water. The reality is richer, and far more interesting. Building a well that lasts for years takes a precise method, technical skill and genuine work alongside the community. Here, step by step, is how a well is built in Africa.

Before digging: why location changes everything

The very first question is not "how do we dig?" but "where do we dig?". Choose the wrong spot and you risk drilling for nothing, or finding water that isn't safe to drink.

That is why everything begins with a field survey carried out by a geologist. Using a device that measures the ground's resistance at different depths, they pinpoint where the groundwater is most accessible and most reliable. This step shapes everything else: the drilling depth, the equipment needed and therefore the cost.

Depth varies enormously from one region to another. In some areas, water lies around twenty metres down. In others, you have to go much deeper, sometimes almost 200 metres. The deeper the water table, the longer and more expensive the work.

The 7 steps to building a well

Once the location is confirmed, the work follows a precise sequence. Here are the 7 steps that turn bare ground into a lasting source of water.

1. The soil survey. The geologist locates the water table and chooses the most promising drilling point.
2. Drilling. A drilling rig bores down to the water table. This dramatic step often takes just a few hours once the machine is in place.
3. Casing. Partly permeable pipes are inserted into the borehole, surrounded by fine gravel, to let water in while filtering out impurities.
4. The pump. The system that brings the water up is installed: a hand, electric or solar pump depending on the village's circumstances.
5. The well apron. A concrete base is poured around the well to stop dust and animals from contaminating the water.
6. Water testing. A sample is sent to a laboratory to check the water is perfectly safe to drink before anyone uses it.
7. The management committee. Villagers are trained in upkeep and minor repairs, often with a shared fund, so the well keeps working for years.

These steps show one thing: drilling, the image everyone remembers, is just one step out of seven. What makes a well last is everything that comes before and after.

How long does it take to build a well?

It's a common question, and the answer often surprises people. The drilling itself may take only a few hours. But the full project takes much longer.

Between the field survey, transporting equipment to villages that are sometimes very isolated, drilling, installing the equipment, testing the water and training the management committee, you should allow anything from several weeks to several months. In the most remote or hard-to-reach areas, it takes longer still.

This is not time wasted: it is what guarantees a solid structure and a community able to keep it going. A well built too quickly, without support, is a well at risk of being abandoned.

What does your donation actually fund?

At LIFE, building a village well follows exactly this approach. The well is dug to around 20 metres and fitted with a mechanical or electric pump. On its own, it brings water to around 500 villagers.

Funding a well in Africa costs €2,650. This covers all 7 steps, from the survey to the management committee. And thanks to the 66% French tax relief on donations to public-interest organisations, your €2,650 gift actually costs around €901 after relief. For a line-by-line breakdown of this budget, our article How much does a well in Africa cost? explains every cost.

Once the well is finished, the donor receives its GPS coordinates, photos and a keepsake booklet. The well can bear a name: yours, a loved one's, or in memory of someone who has passed away. To give a well in tribute to someone, our article Give a well in a loved one's name explains how.

A well, and then what? Water as a starting point

Building a well is never an end in itself. It is the starting point of a wider transformation for an entire village.

A steady, reliable water supply makes it possible to irrigate farmland: food production rises and livestock can drink. Water becomes an economic engine, encouraging crafts, small businesses and new local livelihoods. And because children no longer spend their days fetching water, they can go back to school.

It is this ripple effect that makes a well one of the most useful gifts there is. To understand why giving water offers such good value for impact, our article Donating clean water: the best value for impact explores the question in depth.
