Well Drilling

We can drill anywhere in the state of New Hampshire. Dug wells, driven wells, drilled need water, we will find it. The type of well you will need will depend on the geologic conditions of your location, and your needs. Whatever your well needs, we can provide it.

Dug Well = What most people traditionally think of when they think of a well. A dug well tis a well that was dug by hand to a depth just below the water table. These are then lined with fieldstone, brick, or interlocking concrete tile (in newer wells), and capped with wood, stone, or concrete cover for protection. They were typically 3 or 4 feet in diameter and from 10 to 30 or so feet deep, but in some cases were over 50 ft. deep. The depth is completely dependant upon how far above the water table you are. In the old days, a bucket or hand pump was commonly used, but most now use an electric pump to bring the water to the surface.

Driven Well = Driven wells are an economical alternative to a dug well. These are often used for cabins or vacation cottages where there is groundwater within about 15 feet of the surface and therefore do not need to be as deep. Driven wells are made by driving a small-diameter pipe, either by hand or using power tools, into the water-bearing sand or gravel that lies above the bedrock. A screened well point, designed to filter out sediment, is typically attached to the bottom of the pipe before driving. Whether a driven well is right for you will depend on your proximity to the water table. We are happy to discuss whether a driven well is right for your property.

Drilled Well = A drilled well design will depend on the specific geological conditions at the site. A drilled well consists of a hole bored into the ground and lined with a casing to prevent collapse of the borehole wall. Most wells are drilled an inch or two wider than the casing diameter, which is commonly 6 inches. In the upper portion of the well, unless it is solid rock, the space between the casing and the drilled hole is later “grouted” with cement or bentonite (a special expansive clay). This seals the drilling hole to prevent contaminated surface water from migrating down the well casing. After the well is drilled, it is properly disinfected and capped to ensure it is sanitary until it can be hooked into the customer’s water system.
