Driven WellsLike dug wells, driven wells pull water from the water-saturated zone
above the bedrock. Driven wells can be deeper than dug wells. They are
typically 30 to 50 feet deep and are usually located in areas with thick
sand and gravel deposits where the ground water table is within 15 feet
of the ground’s surface. In the proper geologic setting, driven
wells can be easy and relatively inexpensive to install. Driven Well Construction Features
To minimize this risk, the well cover should be a tight-fitting concrete curb and cap with no cracks and should sit about a foot above the ground. Slope the ground away from the well so that surface water will not pond around the well. If there’s a pit above the well, either to hold the pump or to access the fitting, you may also be able to pour a grout sealant along the outside of the well pipe. Protecting the water quality requires that you maintain proper well construction and monitor your activities around the well. It is also important to follow the same land use precautions around the driven well as described under dug wells.
