Can an existing water well be drilled deeper?

Uncover the compelling reasons homeowners may contemplate deepening their existing water wells, from dwindling water levels to subpar quality or insufficient flow.

While drilling deeper seems like a straightforward fix, the journey is rife with nuances and vital considerations. Dive into the intricacies, explore the possibilities, and arm yourself with the knowledge needed to make the right decision for your water supply.

Assessing The Feasibility Of Well Deepening

If you want a long-lasting pump that is both very efficient and corrosion-resistant, submersible well pumps are fantastic. Since submersible pumps have a drill limit of 120 feet, they are superior to most well pump variations. Submersible pumps can be drilled down to about 400 feet at the same time.

They are a feasible option for rapidly bringing potable water to the surface because of the increased drill limit. They might, however, also pose some risks to homeowners who possess domestic water wells. You will benefit from speaking with your well drilling company and learning about submersible well pumps. If you have a home water well, you should be aware of the following information regarding submersible well pumps:

Understanding Your Well's Design

Age and Construction. A professional can evaluate your well's age, construction materials, and overall condition. Older wells or those built with less robust materials might not be structurally sound enough to handle being deepened.

Existing Depth and Capacity. Knowing the original depth and well yield (water production rate) is essential. Deepening may not be necessary if there's another solution, like pump repair or cleaning.

Geological Considerations

Subsurface Conditions. A professional can use surveys and studies to understand the local geology. They can identify potential problems, like underground rock formations that are difficult or impossible to penetrate, or verify the presence of water-bearing aquifers at deeper levels.

Deeper water sources might have different mineral compositions or contaminants. A professional can assess the potential impact on your water quality.

Finding More Water

There's no guarantee that deepening will encounter a new, abundant aquifer. Professionals can analyze data and estimate the likelihood of finding sufficient water at a deeper level.

Even if water is found deeper, it's crucial to assess the long-term sustainability of the source. Over-pumping can deplete the aquifer and impact neighboring wells.

The Bottom Line

A professional assessment can save you time, money, and frustration. They can provide a realistic picture of the potential benefits and drawbacks of deepening your well. By understanding the well's design, the local geology, and the chance of finding sustainable water, you can make an informed decision about the best course of action for your water needs.

Risks And Limitations

Delving into the depths of well deepening uncovers a landscape fraught with potential risks and limitations. Despite the hopes of discovering bountiful water reservoirs, there exists the stark reality of drilling deeper only to find dry, barren layers beneath.

Moreover, the journey downward may lead to encountering contaminated water pockets, posing threats to both health and safety. Structural integrity stands as another concern, as the process of deepening could inadvertently compromise the stability of the existing well, leading to unforeseen challenges.

Navigating these hazards demands meticulous consideration and expert guidance to ensure the journey towards a deeper well is not paved with unintended consequences.

The Deepening Process

While the specifics can change depending on your location and regulations, here's a general roadmap for the well deepening process:

1. Initial Inspection And Assessment

• Professional Evaluation -A licensed well driller will inspect your existing well, assess its condition, and determine if deepening is feasible.
• Permitting -You'll likely need permits from local authorities before proceeding. The driller can guide you through this process.

2. Well Preparation

• Equipment Setup -The drilling rig will be positioned over the wellhead.
• Existing Well Access -Depending on the deepening method, the well casing (lining) might need to be extended, and the pump and electrical wiring might be temporarily removed.

3. The Deepening Process

• Drilling Method -The chosen drilling method (e.g., rotary drilling, percussion drilling) will depend on the ground conditions.
• Removing Spoil -Crushed rock and soil (spoil) created during drilling will be removed continuously.
• Casing Installation -New well casing might be installed deeper into the wellbore to ensure stability.

4. Well Development

Water Removal -Once the target depth is reached, water development techniques (e.g., surging, pumping) will remove sediment and ensure clear water flow.

5. Completion And Testing

• Well Inspection -A camera inspection may be conducted to check the well's integrity.
• Water Testing -Water samples will be sent for laboratory analysis to ensure it meets drinking water standards.
• Pump Reinstallation -The pump and electrical wiring will be reinstalled at the appropriate depth based on the new water level.

6. Well Owner Responsibilities

• Maintaining Records -Keep detailed records of the deepening process, including well logs, permits, and water test results.
• Wellhead Protection -Ensure the wellhead is properly sealed and protected from contamination.

Alternative Solutions

Deepening your well isn't always the best solution for addressing water supply issues. Here are some effective alternatives to consider:

1. Drilling A New Well

Suitable Conditions - If a professional assessment identifies a more promising water source at a different location on your property, drilling a new well might be a better long-term solution.

2. Water Conservation Measures

Reduce Demand - Implementing water-saving practices throughout your household can significantly reduce your overall water usage. This could include fixing leaky faucets, installing low-flow showerheads and toilets, and watering your lawn efficiently.

3. Water Storage Systems

Peak Usage Management. Installing a large water storage tank can help manage your water supply during periods of high demand. By collecting excess water during off-peak hours, you'll have a reserve during peak usage times, reducing stress on your well.

Choosing The Right Option

The best solution for you will depend on your specific circumstances, water usage patterns, and budget. Consulting with a water well professional can help you evaluate all the options and make an informed decision.

Choosing A Qualified Contractor

Selecting a seasoned and licensed drilling contractoris paramount when embarking on the journey of well deepening. An adept professional, well-versed in the intricacies of local geological formations and abreast of regulatory mandates, is essential for navigating the complexities of the task at hand.

Prioritize experience, seeking out contractors with a proven track record in successfully deepening wells similar to yours. Scrutinize credentials, ensuring proper licensing and adherence to industry standards.

Don't hesitate to request references and testimonials, gaining insight into past performance and client satisfaction.

A thorough vetting process ensures that the chosen contractor possesses the expertise and integrity necessary to safeguard your investment and deliver optimal results.

Benefits Of Drilling An Existing Well Deeper

There is water available year-round- Seasons naturally cause the water level below the surface to rise or fall. When the water table dries out in the summer, well owners typically experience water problems. Deepening an already-existing well can address this issue.

There are fewer problems with contaminated water- The gathered water would not reach the surface, where bacterial contamination is very likely, in a deeper well. Additionally, retrieving water from a deeper level takes longer. As a result, the water becomes safe since the bacteria are killed as they rise to the surface.

You have more storage space- Depending on the subsurface water table, you might or might not receive extra water after excavating the well further. But by doing so, you will undoubtedly boost your well's storage capacity. Since you will still have more gathered water in the reservoir, you can collect additional water, which will be helpful if you experience a water scarcity during the dry season.

How Much Does It Cost To Deepen A Well?

Most tasks will come with a price tag of $1,500 to $12,000. Boat rentals range in price from $15 to $30 per foot of depth, or $50 for more challenging terrain. For shallow depths, the cost of a digging solution might range from $10 to $25 per foot.

Your investment for a well drill will be between $15 and $25. The total cost of installing a well water system is $25 to $65 per foot.

A residential property needs a well that is between 100 and 800 feet deep. Re-drilling existing wells will help the government have a better understanding of subsurface water storage.

A home well can take up to three days to drill. How effectively the filtration rate is achieved depends on the well's depth. If the well in the shallow or dug segment is destroyed or damaged, flooding may result.

It's not advisable to drink specific well water. It is anticipated that a water well will require 100 to 500 feet of drilling. This drill may go down to a depth of 1,000 feet. Wells come in a variety of forms, from drillers and motorized rigs to hand-dug rigs.

In an area with a sufficient aquifer, a drilled well can provide water for decades.
