Compare artesian wells and ordinary wells?

Artesian wells tap into an underground water source that is under pressure, allowing water to flow to the surface without the need for pumping.

What is a jet well pump?

A jet well pump is a type of water pump commonly used for drawing water from deep wells. It operates by creating a vacuum that pulls water into the pump through a jet assembly, where high-velocity water creates a suction effect. These pumps are typically installed above ground and are suitable for applications where the water level is below the pump, making them effective for deeper wells. Jet well pumps are often used in residential, agricultural, and irrigation systems.
