Can You Drill an Existing Well Deeper

Yes, you can drill an existing well deeper. This process is known as re-drilling and involves drilling down to the water table below the original location of the well. The most important part of this process is ensuring that the new depth does not exceed any local or state regulations concerning groundwater limits.

After determining if it meets all regulatory requirements, a licensed water well contractor will use specialized equipment to re-drill the existing well. They may also need to install additional casings and screens depending on how deep they plan on going before reaching groundwater.

  • Research and Acquire a Permit: Before attempting to drill an existing well deeper, it is important to research the applicable regulations and acquire any necessary permits for your area. Depending on where you are located, this process may be handled through local government agencies or water management districts.
  • Obtain Professional Assistance: Drilling a well deeper requires specialized knowledge and experience in order to ensure that the job is done safely and properly. It is recommended that you contact professional contractors who specialize in drilling wells for assistance with this project.
  • Prepare the Well Site: Once all of the proper paperwork has been obtained, prepare the site by clearing debris away from around the existing well casing before beginning any work on it
  • This will help ensure that no material gets stuck inside while drilling down further into the earth’s surface belowground level.
  • Inspect Existing Casing : Carefully inspect the existing casing for corrosion or damage before continuing with any operations on it as these issues could result in weakened structural integrity when attempting to drill further into soil layers beneath ground level . If extensive wear or deterioration is detected , then replacing parts of casings may be required prior to drilling deeper
  • Attach New Drill Bits : Utilizing various sized drill bits , attach them onto motorized equipment such as rotary drills which can create bores into different depths depending upon sizes selected. Slowly operate machinery downward creating new passageways within already-existing boreholes until desired depth levels have been reached following safety protocols established by governing authorities during initial permitting phases of project completion

How Much Does It Cost to Deepen a Well

The cost of deepening a well can vary greatly depending on factors such as the depth needed, the type of well being drilled, access to the site and other considerations. Typically, you should expect to spend anywhere from $500 – $3,000 for shallow wells (under 50 feet) to over $10,000 for deeper wells (over 200 feet). It is important to get an estimate from a professional driller before deciding whether or not to proceed with this project.

How Close to an Old Well Can You Drill a New One

It is not recommended that you drill a new well within 50 feet of an old one. This is because the two wells may interfere with each other, causing pressure loss or water contamination in both wells. If drilling closer than 50 feet apart, it’s important to consult local regulations and guidelines for your area as some places have stricter requirements.

Additionally, consider talking to a professional well driller who can provide insight into safely drilling a new well near an existing one.

The Deeper the Well, the Better the Water

When it comes to well water, the deeper the well is dug, the better quality of water you can expect. Deeper wells provide access to aquifers which are underground sources of fresh and uncontaminated water that have not been exposed to surface runoff or other environmental contaminants. A deeper well also has less chance of being affected by seasonal changes in ground temperature or evaporation, resulting in a more consistent and higher quality of drinking water.

How to Make a Shallow Well Deeper

Making a shallow well deeper can be an involved process, depending on the complexity of your current setup and how deep you want to make it. First, you’ll need to remove the existing pump and pipes from the well, then use a drill rig to bore down into new depths. Once that is finished, you’ll have to install new piping and pumps for water extraction as well as proper seals at both ends of each pipe.

Finally, if necessary, you may also need to add additional supports around your newly drilled hole in order for it to remain structurally sound.

Well Deepening

Well deepening is a process in which the depth of an existing well is increased to reach more plentiful groundwater supplies. This can be done through either excavation or drilling, depending on the structure of the well and its original construction techniques. Well deepening can provide access to more reliable water sources and help improve water quality for those living nearby.

It’s important to note that this process should only be undertaken with proper guidance from experienced professionals since it requires special equipment and knowledge about local geology and regulations.

How Much Does It Cost to Drill an Existing Well Deeper?

It can cost anywhere from $2,000 to $4,000 (or more) to drill an existing well deeper. Factors such as the depth of the new hole and other factors including soil type, geological structure, access for equipment and the condition of the well itself all affect price. Generally speaking, if a boring contractor is able to use their existing equipment and only needs to go down 15 or 30 feet in order to reach a water source then this will be less expensive than if they have to construct a whole new borehole which requires additional drilling materials and technology.

When considering how much it may cost you should always obtain several quotes first so that you can compare prices between contractors.

Can You Increase the Depth of a Well?

Increasing the depth of a well can be done, but it requires specialized knowledge and equipment. It is not recommended that you try to do this yourself as there are many safety considerations involved in drilling deeper into the ground. The first step would be to hire an experienced contractor who specializes in deep wells.

They will need to assess the area around your existing well and determine if it is feasible to dig a deeper one – depending on how deep your current well is, they may need additional excavation equipment or even blasting materials. Once they have determined what needs to be done, they should provide guidance on how best to proceed with the project safely and efficiently. In addition, since water levels can vary from season-to-season, consider having them perform regular maintenance tests throughout the year so you know when it’s time for another round of deepening work.

Above all else though, remember that increasing the depth of a well should always be done under professional supervision – never attempt any kind of repair or alteration without consulting an expert first!

What Happens If You Drill a Well Too Deep?

Drilling a well too deep can be a dangerous and costly endeavor. If the well is drilled to depths beyond what it was designed for, water pressure may become too high and cause the borehole walls to fail, leading to an uncontrolled release of pressurized ground water. Additionally, drilling deeper than necessary increases costs associated with the drilling process.

Furthermore, when a well is drilled too deep it can penetrate geological formations that are not conducive to safe or reliable groundwater production such as sandstone or shale layers which may reduce flow rate and contain minerals that make the water unsuitable for use. Finally, if extreme care is not taken during the drilling operation there exists a risk of penetrating into an aquifer containing contaminated waters which could lead to serious health risks if used for drinking or agricultural purposes without proper treatment first.

How Many Years Does a Water Well Last?

A water well can last anywhere from a few years to many decades depending on the design, construction methods and maintenance of the well. A properly designed and constructed well can yield clean drinking water for up to 20 years or more with regular maintenance. The life expectancy of a water well is largely dependent upon the type of materials used in its construction as different types of rock and soils will have varying levels of durability when exposed to underground elements like moisture, temperature fluctuations, erosion, chemical reactions, etc.

Generally speaking however, newer wells that are constructed using modern technologies such as steel casing pipes and reinforced concrete walls tend to have longer lifespans than those built with older methods such as sandstone masonry or hand-dug wells which may only last 10-15 years before needing repairs or replacement due to wear and tear from natural causes. Additionally certain contaminants in ground water sources could potentially reduce the lifespan of even new wells by corroding their internal components over time so it’s important to consider this factor when deciding how long your well should expect to last.


In conclusion, deepening an existing well can be a viable option for those wishing to access additional groundwater. It is important to consider the cost and potential risks that come with this process before making any decisions. Fortunately, there are experienced professionals who specialize in drilling wells and can help determine whether or not it is possible to deepen an existing well on your property.

With careful planning and research, you may be able to find a reliable solution for accessing more groundwater without having to start from scratch.
