Borehole wells are narrow holes drilled into the ground that tap into underground aquifers. As the borehole is drilled, a lining of plastic, steel, or iron is sunk to protect the hole from collapse. The bottom section of the lining has slots to allow water to enter the borehole. Gravel is placed around the bottom of the lining to improve ﬂow and provide ﬁltration.
A pump is required to bring water from the borehole to the surface. LDS Charities usually recommends using handpumps for sustainability. When borehole wells with handpumps are built, the community is given the responsibility for operation and maintenance of the system. Before a borehole is placed in a community, LDS Charities makes sure spare parts can be purchased within a reasonable distance from the village.
When engineers drill a borehole, they flush it out with water. Water sprays out from the hole and showers everything around it. It’s not uncommon for villagers to sing and dance and say, "It's raining from the ground." To many villagers, it's a completely new concept that clean, pure water is flowing right underneath them.
