Types of Water Wells

Bored Wells

Bored wells are typically constructed with a rotary drill or auger that bores a hole into the ground. The hole is then lined with a perforated liner pipe, which allows water to enter the well. Bored wells are relatively inexpensive to construct and can be drilled to depths of up to 500 feet. However, they are not suitable for all soil types and can be susceptible to contamination from surface water.

Driven Wells

Driven wells are created by driving a pipe into the ground using a sledgehammer or pile driver. The pipe is typically fitted with a screened tip at the bottom to allow water to enter. Driven wells are inexpensive to construct and can be installed in a variety of soil types. However, they are limited in depth to about 30 feet and can be susceptible to contamination from surface water.

Drilled Wells

Drilled wells are constructed by drilling a hole into the ground using a rotary drill or percussion drill. The hole is then lined with a casing pipe, which keeps the hole from collapsing. Drilled wells can be constructed to depths of several thousand feet and are typically used for municipal and industrial water supplies. They are more expensive to construct than bored and driven wells.

Type of Well	Construction Method	Depth	Cost	Susceptibility to Contamination
Bored	Rotary drill or auger	Up to 500 feet	Inexpensive	High
Driven	Sledgehammer or pile driver	Up to 30 feet	Inexpensive	High
Drilled	Rotary drill or percussion drill	Up to several thousand feet	Expensive	Low

Choosing the Right Location

The success of your water well project depends heavily on choosing the right location. Here are key factors to consider:

Water Table Depth

Determine the depth of the water table in your area. This information can be obtained from local well records or groundwater maps. Aim for a location where the water table is relatively shallow (typically less than 100 feet), ensuring sufficient water supply.

Geology

Study the local geology to understand the layers of soil and rock beneath your property. The ideal location is one where there are multiple layers of permeable materials, such as sand or gravel, that allow water to flow easily.

Proximity to Surface Water

Avoid locations near surface water bodies like rivers or streams, as they can create high flow rates and contamination risks. Maintain a safe distance to prevent cross-contamination and minimize the likelihood of surface water infiltration into your well.

Topography and Drainage

Choose a location on slightly elevated ground, ensuring proper drainage. Avoid low-lying areas prone to flooding or water accumulation, as they can increase the risk of contamination.

Land Use

Consider the surrounding land use. Avoid areas with potential contamination sources, such as industrial sites, landfills, or septic tanks. The ideal location should be free from potential pollutants that could seep into the groundwater.

Factor	Considerations
Water Table Depth	< 100 feet for sufficient supply
Geology	Permeable layers (sand, gravel)
Proximity to Surface Water	Safe distance from rivers, streams
Topography and Drainage	Elevated ground, good drainage

How To Build A Water Well

Building a water well is a great way to provide your home or business with a source of fresh, clean water. However, it’s important to note that well drilling is a complex and dangerous process that should only be undertaken by experienced professionals. If you’re considering drilling a water well, it’s important to do your research and find a reputable drilling company that can safely and efficiently complete the project.

The first step in building a water well is to determine the location of the well. The location of the well will be determined by a number of factors, including the depth of the water table, the type of soil, and the presence of any underground obstacles. Once the location of the well has been determined, the drilling process can begin.

The drilling process involves using a large drill bit to bore a hole into the ground. The drill bit is attached to a drilling rig, which provides the power and rotation necessary to drill the hole. The drilling process can take several days or even weeks, depending on the depth of the well and the type of soil.

Once the hole has been drilled, a casing is inserted into the hole. The casing is a pipe that prevents the hole from collapsing and allows water to flow into the well. The casing is then sealed at the bottom of the hole and a screen is installed at the top of the casing. The screen prevents sand and other particles from entering the well.

Once the casing and screen have been installed, the well is ready to be used. The water from the well can be pumped to the surface using a pump. The pump can be powered by electricity, gasoline, or solar power.
