What is an artesian well?

An artesian well taps into a natural underground water source—also known as an aquifer—that is under pressure.

Water is trapped in permeable (porous) layers of rock or soil, confined by impermeable (non-porous) layers above and below. When a well is drilled into this confined aquifer, natural pressure pushes the water toward the surface.

Artesian wells are frequently used for drinking water, irrigation, and industrial purposes. They provide a reliable source of water in regions where surface water is scarce or contaminated.

Artesian wells are very deep, ranging from 60 to 400 feet, depending on the geography of the area and the depth of the water source.

The Advantages and Disadvantages of an Artesian Well

The benefits:

Water Quality: Water from an artesian well is known for its purity and high quality, as it comes from deep aquifers and undergoes natural filtration.

Reliability: Artesian wells provide a constant source of water, even during droughts or when surface water is scarce.

Less prone to contamination: Its fundamental nature makes it less vulnerable to pollutants.

Independence: You are not dependent on public water services, which can be an advantage in rural areas.

Beneficial Minerals: Artesian water contains minerals that are essential for health. It contains minerals such as calcium, fluoride, and electrolytes, which are beneficial to human and animal health.

Long-term savings: Although the initial drilling may be expensive, maintenance costs are generally low.

The drawbacks:

Geological risks: The depth of the well, the types of rock, and the extraction process can affect water quality.

Variable quality: Poor water quality can be a problem if the well is not properly tested before the water is consumed.

Sediment: Proper screening in the well helps prevent sediment from entering the water.

Corrosion and Contamination: High pressure and a constant flow rate can cause corrosion of the extraction tube and contamination of the water.

Cost of Drilling an Artesian Well

In 2024, the cost of drilling an artesian well generally ranges from $85 to $100 per foot of casing. Before planning the drilling, it is essential to determine the optimal location to avoid unnecessary costs. Several factors influence the total cost of drilling, including the desired depth and the associated expenses.

Some well drillers charge a minimum rate for the first 100 feet, with an additional charge per foot beyond that. In remote or hard-to-reach areas, additional fees may also apply.

We recommend consulting with drilling professionals to obtain accurate estimates tailored to your specific situation.

Tips for maintaining an artesian well:

  1. Water surface in the well free of debris: Check that the water surface in the well is clean and free of any debris.
  2. Keep an eye out for objects around the well: Prevent dead animals or plant debris, such as dead leaves or branches, from accumulating near the well.
  3. Avoid standing water near the well
  4. Avoid using pesticides or fertilizers near the well, as they can contaminate the water.
  5. Check that the pipes do not have any holes or cracks that could allow surface water or debris to enter the well.
  6. Make sure the well vent is free of any obstructions.
  7. Do not allow liquids or waste to flow into the well.
  8. Chemicals: Oil, solvents, paint, etc., must not be flushed down the toilet near the well.
