What Is the Difference Between a Drilled Well and a Driven Well?

Understanding Your Water Well Options in Springfield, OH

If you’re planning a new well for your home, farm, or business, understanding the differences between well types is essential. The two most common types of private water wells are drilled wells and driven wells. While both serve the purpose of providing access to groundwater, their construction, depth, performance, and longevity vary significantly.

At Eaton Well & Pump, we provide expert well drilling in Springfield, OH, helping our customers select the most effective solution based on property needs and local groundwater conditions.

What Is a Drilled Well?

A drilled well is created using specialized rotary drilling equipment that bores deep into the earth, often between 100 and 400 feet, depending on the geology and required water yield. These wells are encased in steel or plastic casing and sealed with grout to prevent contaminants from reaching the water supply.

Drilled wells are ideal for reaching deep aquifers, making them more reliable and capable of supporting high-demand water usage. They are commonly used for residential homes, agricultural irrigation, and commercial facilities. Properly constructed and maintained, drilled wells can provide clean water for several decades.

What Is a Driven Well?

A driven well is formed by driving a small-diameter pipe directly into a shallow water table, typically to a depth of less than 50 feet. These wells are only suitable in areas with loose, sandy soil and a consistently high groundwater level.

Driven wells are relatively easy and inexpensive to install, but their shallow depth makes them more susceptible to surface contamination and seasonal fluctuations in water availability. While they can be effective for low-demand applications, such as supplying water to outbuildings or seasonal cabins, they are not ideal for homes or farms requiring steady, high-volume water flow.

Key Differences Between Drilled and Driven Wells

Depth and Water Source

  • Drilled wells reach deeper, accessing groundwater far below the surface.
  • Driven wells tap into shallow water tables that are often less consistent.

Installation Method

  • Drilled wells require heavy rotary drilling equipment and professional installation.
  • Driven wells are installed using a pipe-driving method, typically with light machinery.

Water Yield and Pressure

  • Drilled wells offer higher yield and are capable of sustaining continuous, high-volume use.
  • Driven wells generally have lower flow rates, which may not meet household or agricultural demands.

Contamination Risk

  • Drilled wells, when sealed correctly, are better protected from surface contaminants.
  • Driven wells have a higher risk of contamination due to their shallow depth.

Cost and Lifespan

  • Drilled wells require more upfront investment but offer greater longevity and reliability.
  • Driven wells are less expensive to install but may need more frequent maintenance or replacement.

Which Well Type Is Right for You in Springfield, OH?

In Springfield and the surrounding areas, drilled wells are typically the recommended option. The region’s geology, combined with the need for year-round, reliable water access, makes drilled wells the most practical long-term solution for homes, farms, and businesses.

Conclusion

Choosing between a drilled and a driven well depends on your location, water usage needs, and budget. While driven wells may work for light, short-term use in sandy soil conditions, drilled wells provide the durability, water quality, and performance most property owners require in Springfield, OH.
