10.3 meters.
But if the pump has a long tube immersed in the water, say as on a suction mining plant, then the 10.3m limit applies only to the part of the pipe above the surface.
(And in both answers ignoring altitude effects.)
The further any Pump has to lift or push water to get it to the surface the less pressure it will be able to make as an end result. More horsepower and Impellers are required as the depth to water increases.
To get water from a 45-feet depth tube well, you would typically use a submersible pump or a hand pump. These pumps are designed to draw water from deep underground wells and bring it to the surface for use. Once installed, the pump can be operated manually or through a power source to extract water from the tube well.
That depends on the depth of the water in the well and the size of the pump.
This is a pump that lift a surface water to the nearby water treatment plant.

Depth to lower water level
This varies from pump to pump because centrifugal pumps can be designed for various applications. The maximum height a pump can pump water depends on size of pipe/water column, friction, power available etc. This is often reffered to as the head of the pump. A water company would probably have some centrifugal pumps capable pumping to over 300m in a 30 inch main.
maximum current of a 1hp
When the pump is not running, the water pressure at the output pipe of the pump will be equal to the static pressure of the water source acting on the pipe. This static pressure varies depending on the elevation and depth of the water source.
Submarines change their depth by use of ballast tanks. To dive, they open their tanks so that they become filled with water. They also angle their dive planes. To surface, they pump the water out of their tanks and fill them with pressurised air.
they pump underground water to the surface
In artesian wells the water is forced to the surface by ground pressure. In conventional wells a pump is used to pump the water up.
