Build a Simple Well 💧

🛠️ Perforated casing with filter tip: The completed well rests on a robust, perforated tube finished with a tip; a screen attached at the end lets water pass while keeping out fine particles (sand, debris), ensuring clear water from the moment it’s captured.

🔧 Driven method (battering): A heavy drill bit, suspended on a rope or cable, is repeatedly lifted and dropped; the impact breaks up the soil and gradually drives the casing down to the water table.

💦 Water injection method: Pressurized water is injected into the tube; as it escapes at the bottom, it fluidizes the soil and facilitates the successive insertion of casing segments—ideal for loose to compact soils.

🏗️ Augering method: A wide circular casing is first erected at the surface, and then excavation continues inside; under its own weight, the casing sinks while excavation progresses, allowing for much larger diameters for collective use.

📏 Depth & diameter: Wells are generally shallow, from less than 15 m up to 40 m depending on the soil and method; diameters range from 25 to 100 mm standard, and can reach several meters for augered wells.

⏱️ Construction time: Full cycle of [get_acf_subfield field=”puits_simple” post_id=”option” path=”delais”], from site selection to initial potability tests.

👥 Number of beneficiaries: Each completed well can serve up to 50 people, providing sustainable access to safe drinking water.
