Borewells are narrow, deep vertical shafts drilled into the earth to access clean groundwater from underground aquifers. A motorized submersible pump is typically installed at the bottom to draw water to the surface for domestic, agricultural, or industrial use. The well is lined with durable PVC or metal casing pipes to prevent the surrounding soil from collapsing and to keep surface contaminants from polluting the water supply. As a reliable and independent water source, borewells are essential for providing a consistent supply in regions where municipal water or surface sources are limited.
