What is a Caisson Well Pump?

A type of well that is wider than other wells, reinforced with concrete and has a reinforced ground. They are usually constructed close to water beds. With the help of a caisson well pump, they can meet long-term and continuous clean water needs because they are robustly built. It can also be preferred for collecting surface water.

A Caisson Well Pump is a type of pump used in water wells to draw water from underground sources. It is housed within a caisson, a watertight structure typically sunk into the ground to access water or to create a safe and dry working environment below ground level. Here’s a breakdown:

Key Features:

Caisson Structure:
- Made of steel, concrete, or other sturdy materials.
- Protects the well shaft and prevents the entry of contaminants.
- Keeps the surrounding soil stable, especially in loose or sandy conditions.
Pump Mechanism:
- The pump can be submersible (installed underwater inside the well) or jet (installed above ground).
- The choice depends on the well’s depth and water flow requirements.
Applications:
- Commonly used for municipal water supplies, irrigation, and industrial purposes.
- Ideal for deep wells or wells located in areas with challenging soil conditions.
Advantages:
- Provides a secure and durable solution for accessing groundwater.
- Helps maintain water quality by isolating the well from external contaminants.
Operation:
- Water is drawn up through pipes using suction or pressure mechanisms, depending on the pump type.

Caisson wells and their pumps are particularly advantageous in areas where traditional well construction may not be feasible due to loose soil or high water tables.
