How is a driven-point well installed?
Installation of a driven-point well begins by driving the point, attached to a single length of pipe, into the ground. The driving is often done by hand using a post driver – a short length of weighted steel pipe with handles. Some well point installers use mechanical, motor-operated equipment with a tripod to raise and lower the heavy driver. Sections of steel pipe are added as the pipe is driven deeper into the ground until a sufficient depth below the water table is reached. A special fitting called a drive cap is threaded onto the top of the pipe to protect the pipe threads while driving and to prevent contaminants from entering the pipe. Sometimes a shallow starter hole is dug or augured at the ground surface to accommodate the pipe lengths and facilitate the starting of the driving process.
