They are essential for providing potable water, particularly in areas where other sources, like rivers or lakes, may be contaminated.
How Shallow Wells Work
The basic functioning of a shallow well involves creating a hole in the ground that reaches the water table, which is the upper level of an underground water source. Water enters the well through the surrounding soil, and it can be extracted using various methods such as hand pumps or electric pumps.
Types of Shallow Wells
- Dug Wells: These wells are manually excavated using simple tools. They are typically lined with stones or bricks to prevent collapse and contamination.
- Drilled Wells: Using specialized drilling equipment, these wells reach deeper layers of groundwater. They provide a more reliable water source but require higher initial investment.
- Bored Wells: These are constructed with a boring machine and are usually lined with plastic or concrete to maintain structural integrity.
