We frequently receive calls from customers with no knowledge of wells or well systems. Our philosophy is to thoroughly explain the well construction and well system operation in a manner that our customers and potential customers will understand. We have compiled a list of commonly asked questions as asked by our customers. Today, most wells are made by drilling into rock layers using drilling machines or rigs to access water deep beneath the surface. Most residential wells are drilled to a diameter of 6 inches.
All wells require casing to seal off possible contaminants at or near the ground surface.
Casing may not be needed for the entire depth of the well. When drilling in the rock formations in Eastern Pennsylvania generally the casing must be installed ten feet into bedrock. Softer formations may require additional lengths of casing. This is a Board of Health requirement so that ground water runoff does not enter the well. With the equipment that is used today, most wells can be drilled in a day.
