What is a well point?
People do not know the difference between a well point and a borehole. Let’s start with the well point. A well point is most of the time drilled with a drill or by using water that is forced down a pipe that is been pressed downwards in the sand. The water pushes the sand out on the side of the pipe. The trade mark of a well point is that the water is been sucked out of the ground with a pipe that is located in the sand. The pipe is permanent in the sand. The pump is above the ground.
What is a borehole?
A borehole is a hole in the ground that could be a few meters deep up to a hundred and more meters deep. The pump is at the bottom of the hole. Water is been forced up to the surface by the borehole pump. The borehole pump can be removed from the hole for replacement and then be lowered in the hole to pump water.
Difference between well point and borehole.
The well point pipe is permanent in the ground and sucks water from the ground. The borehole is a hole in the ground with a pump at the bottom of the hole. Water is been pumped from the bottom where the water is been sucked from the ground by the well point pump. The borehole water have a tendency to have high levels of Sodium and chloride.
There is a difference between borehole water and well point water.
