When a drilled well no longer produces enough water, hydrofracking may offer an alternative to immediately drilling a replacement well.
It is not the right solution for every well, and it does not guarantee a specific result. But for certain low-producing bedrock wells, hydrofracking may help open or improve water-bearing fractures and increase the flow of water into the well.
The important question is not simply, “Does hydrofracking work?” It is whether the well is a suitable candidate and whether the low-water problem is actually coming from the well rather than the pump, pressure tank, controls, or plumbing.
What Is Hydrofracking a Water Well?
Hydrofracking, also called hydrofracturing, is a well-rehabilitation method used on some drilled bedrock wells.
The process isolates a section of the well and introduces water under controlled pressure. The goal is to open, clean, or improve existing fractures in the surrounding rock so more groundwater can move into the well.
Hydrofracking is different from hydraulic fracturing used in oil and gas development. In water-well work, the purpose is to improve groundwater entry into an existing well.
Kent Well Drilling provides hydrofracking services for qualifying wells in Northern Minnesota and parts of Northern Wisconsin.
What Problems Can Hydrofracking Address?
Hydrofracking may be considered when a drilled bedrock well:
- Produces less water than the property needs
- Has declined in yield over time
- Recovers too slowly after normal use
- Runs short during high-demand periods
- Has water-bearing fractures that may be restricted or poorly connected
The process is aimed at well yield, not household pressure by itself.
If the problem is a worn pump, failed pressure tank, clogged filter, leaking line, or faulty switch, hydrofracking will not correct that equipment problem. A full system evaluation should come first.
Low Water Pressure Is Not Always Low Well Yield
Pressure and yield are related, but they are not the same.
Pressure is the force that moves water through the plumbing. Yield is the amount of water the well can produce over time.
A home can have low pressure even when the well has enough water. A failing pressure tank, pump problem, clogged filter, or plumbing restriction may be responsible.
Our guide to possible causes of low well water pressure explains why diagnosis matters before treating the well itself.
How the Hydrofracking Process Works
The exact process depends on the well and equipment, but hydrofracking generally involves several steps.
1. Evaluate the well
The contractor reviews the well’s construction, depth, casing, condition, history, and current production. The pump may need to be removed before work begins.
2. Isolate part of the borehole
Specialized equipment is used to seal off a section of the drilled well. This allows pressure to be directed into selected areas rather than the entire borehole.
3. Apply controlled water pressure
Water is introduced under pressure to work on existing fractures in the bedrock. The objective is to improve the pathways that allow groundwater to enter the well.
4. Develop and test the well
After treatment, the well may be developed and evaluated to determine whether production has changed. Pump installation and system testing follow as appropriate.
The process should be performed by experienced well professionals using equipment designed for water-well hydrofracking.
What Makes a Well a Good Candidate?
Hydrofracking is generally associated with drilled bedrock wells, but not every bedrock well is a good candidate.
A contractor may consider:
- Well depth and construction
- Casing condition
- Bedrock interval
- Current yield and recovery
- Age and history of the well
- Condition of the borehole
- Water-quality concerns
- Whether equipment problems have been ruled out
- Whether the well can be safely isolated and treated
Some wells may have structural, construction, contamination, or location issues that make another solution more appropriate.
When Hydrofracking May Not Be the Right Answer
Hydrofracking may not solve the problem if:
- The pump or pressure system is failing
- The main water line is leaking
- The well is not a drilled bedrock well suited to the process
- The casing or well structure has serious problems
- The well has contamination concerns
- The property’s water demand far exceeds what the existing well can reasonably support
- The well is poorly located or does not meet current needs
In those situations, pump repair, pressure-system service, well repair, rehabilitation, or new drilling may be considered instead.
How Much Improvement Can Hydrofracking Produce?
Results vary from well to well.
Hydrofracking works with the fractures and groundwater conditions already present in the surrounding rock. Those conditions cannot be seen or controlled perfectly from the surface.
A reputable contractor should explain the process and the uncertainty without guaranteeing a particular number of gallons per minute.
The useful comparison is whether the potential improvement and cost make sense compared with continued shortages, equipment changes, storage options, or drilling a replacement well.
Hydrofracking vs. Drilling a New Well
A replacement well may provide a better long-term answer in some situations, but it is a larger project and still involves underground uncertainty.
Hydrofracking may be worth evaluating when the existing well is otherwise usable and the primary concern is low production from a bedrock formation.
New well drilling may make more sense when:
- The current well has major structural problems
- The well is contaminated or poorly located
- The well does not meet the property’s present demand
- The existing construction is unsuitable
- Hydrofracking is not technically appropriate
- Previous rehabilitation attempts have not provided adequate improvement

Hydrofracking vs. Adding Water Storage
Some low-yield systems use storage to collect water gradually and supply higher short-term demand.
Storage does not increase the well’s natural yield. Instead, it changes how available water is managed. Hydrofracking attempts to improve the rate at which water enters the well.
Which option makes sense depends on the well, property demand, available space, equipment, maintenance considerations, and project cost.
Signs Your Well May Be Low-Producing
Possible signs include:
- Water starts normally but fades during longer use
- The well needs significant time to recover
- Water runs out during laundry, showers, or irrigation
- Air or sputtering appears after heavy demand
- The pump has been tested but cannot maintain supply
- Household demand has increased beyond the well’s former capacity
These symptoms can also overlap with pump and pressure-system problems. Testing is needed before concluding that yield is the cause.
What Should Be Checked Before Hydrofracking?
A complete evaluation may include:
- Pump performance
- Pressure tank and switch operation
- Electrical controls
- Leaks and check valves
- Static and pumping water levels
- Well recovery
- Existing well records
- Water quality
- Well construction and casing condition
This helps avoid treating the well when the actual problem is elsewhere in the system.
Can Hydrofracking Affect Water Quality?
Work on a well can temporarily disturb sediment or change water clarity. The well may require development, flushing, and testing after treatment.
Any persistent change in color, odor, taste, or sediment should be evaluated. Water used for drinking should follow applicable testing recommendations and requirements.
Questions to Ask a Hydrofracking Contractor
- Is my well a suitable candidate?
- What information do you need about the well?
- Have pump and pressure-system problems been ruled out?
- What does the process include?
- What equipment must be removed?
- How will the well be tested afterward?
- What outcomes are possible, and what cannot be guaranteed?
- What alternatives should I consider?
Clear answers are especially important because the result depends on underground conditions.
What If Hydrofracking Does Not Make Sense?
Other possible next steps may include:
- Pump or pressure-system repair
- Well cleaning or rehabilitation
- Changes to water-use patterns
- Water storage
- Equipment upgrades
- Drilling a replacement well

Talk With a Local Hydrofracking Contractor
A low-producing well does not automatically need to be abandoned or replaced. Hydrofracking may be one option when an existing drilled bedrock well is otherwise suitable.
Kent Well Drilling can evaluate the well and connected pump system, explain whether hydrofracking is appropriate, and discuss other options when it is not.
