Product Description

Water Well Drive Point

A driven point well – sometimes called a sand point – is a small diameter well made by connecting lengths of 1-1/4” or 2” diameter steel pipe together with threaded couplings. Threaded to the bottom of the string of pipe is a drive-point well screen. The screen is usually 2 to 3 feet long with a hardened steel tip or drive-point at the bottom.

The purpose of the screen is to allow groundwater to flow into the well but keep the surrounding sand out. Water can then be pumped up through the pipe to the surface. The hardened steel drive-point tip allows the well to be more easily driven into the ground. The pipe and drive-point resemble a long spear.

Product Advantages

Installed properly using a high quality drive-point, it can provide an adequate supply of safe drinking water, especially for cottages and many residences. However, because of installation limitations, driven point wells are usually only found in areas having permeable sandy soils and a high water table.
