In the nearly 40 years Skillings & Sons has been in the well drilling business, we’ve found that people often don’t think about the work and technology that goes into having a reliable source of clean, great-tasting drinking water. Although many homeowners in New Hampshire and Massachusetts draw their water from a private well, chances are they didn’t have to hire a well contractor themselves and were not there when the well was drilled. Watching a well-drilling rig in action can be pretty impressive; here’s how it works.
The company is the world’s best water boring tools supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
How does a well drilling rig work?
A well drilling rig is a large piece of equipment that must be brought to a site by truck and put into place on the site where the well is to be dug. Drilling rigs are either rotary drillers, which bore down into the earth using a circular motion or a “pounder,” which raises and lower a heavy weight in a technique known as "cable drilling" to punch holes. A rotary drill rig uses an assortment of bits. The most common types are long cable bits or interlocking steel bits – both which rotate in a clockwise direction to bore into the earth and loosen the soil. Rock is carried to the surface as the bit turns. The turning bit often gets hot, so water or mud is used to keep the drilling bits cool.
The goal of well drilling is to reach an aquifer or water source deep below the ground, but that’s not where the drilling stops. To ensure the well will have ample supply and a long life, the well drilling company will continue to drill below the water table. Bedrock wells are usually between 100 and 500 feet but in some cases can be more than 500-feet-deep.
Installing well casings
Casings are long pipes made of steel or plastic which line the new well to prevent collapse during drilling and contamination of the water below. Between the well wall and the casing is a two-inch gap called the annulus. This is filled with gravel and capped with cement for the last twenty feet to the surface to prevent contaminants from the surface getting into the well and ruining the water source supplying it. Casings also help protect the well from freezing in extreme cold during the winter months.
While some well drilling companies install the casing as it drills, others might also install the piping separately after the drilling is complete.
Keeping the water source clean
To prevent debris and other surface contaminants from getting into the water supply at the bottom of the well, filters must be installed. These filters also prevent larger particles from being drawn into the water pump. Once drilling is complete, a screen is placed at the bottom of the well casing. Gravel, a natural filtration medium, is also used at the bottom of the well.
Experience and technology
Hundreds of years ago, well drilling meant digging deep into the ground with shovels and buckets until you hit ground water. Today there are a number of techniques and methods well drilling contractors can employ to ensure homeowners have a reliable source of water for many years.

Directional boring is a method for laying underground pipes, wires, and conduits without digging trenches. It has a minimum impact on the surface, making it the method of choice in instances when traditional trenching is not viable or where minimal surface disturbance is desired.
Drilling a pilot hole with a small diameter along a predetermined underground path is followed by widening the bore to accommodate the required pipeline. The pipeline is then dragged into the expanded hole, forming a continuous section of pipe with only its two endpoints exposed.
The approach is adaptable to diverse soil conditions and is capable of traversing diverse surface impediments, including roads, wetlands, and bodies of water. Different pipe materials can be used with directional boring if the pipe’s qualities permit installation and operation below acceptable stress limits.
Directional boring equipment depends on numerous criteria, such as the length of the intended crossing, the qualities of the pipeline to be laid, and the predicted subsurface conditions.
For longer and more complex crossings, tractor-trailer-mounted augers are used. These machines are capable of generating 1.32 million pounds of thrust/pullback force and 150,000 foot-pounds of rotary force. They are utilized in conjunction with other equipment, such as a drilling fluid reclaimer, high-volume pump, excavator, and a variety of auxiliary equipment, to aid with standard operations.
Smaller, more transportable equipment with thrust/push forces ranging from 5,000 to 100,000 pounds is available for smaller bores. They are utilized for operations such as connecting a home’s basement to a nearby shared water pipe and may not require drilling fluid or water alone.
Also available in a variety of sizes and forms are drill bits, reamers, hole-openers, and swab tools, among others. Installed on the drill string to perform operations, these tools are made of materials such as tungsten carbide alloys, polycrystalline diamond (PCD), or high-carbon steel. The method of advancement differs between soil and rock crossings, with hydraulic excavation being the primary approach for unconsolidated soils and a combination of hydraulic excavation and mechanical operations for rock formations.
How much does directional boring cost? The cost of horizontal directional drilling can vary based on a number of variables, including the type of project (residential or commercial), location, soil conditions, and length of the bore. Here is a breakdown of cost-related factors to consider for residential and commercial directional drilling projects:

The best way to get an accurate estimate for directional boring costs is to contact a local directional boring contractor specializing in this type of work. They can assess the specific needs of your project and provide a detailed quote.
What is construction directional boring? In construction, directional boring is distinct from other forms of horizontal directional drilling. Directional boring in construction involves the non-disruptive placement of underground pipes, conduits, and cables to create a path for underground utilities and services in a construction project.
This technique is frequently employed in new construction and remodeling projects to minimize the impact on above-ground structures and surfaces and preserve excavation safety.
The following bullet points illustrate some of the distinctions between construction directional boring and other forms of directional drilling:
Directional drilling in construction is intended to minimize the impact on above-ground structures, surfaces, and utilities. Other techniques of directional drilling may be subject to various limitations and have a bigger influence on the ecosystem above ground.
