Signs Your Well Is Running Dry: Warning Signs & Solutions
Published February 1, 2026 | 11 min read
Few things are more stressful for a well owner than suspecting their water supply is failing. Whether it's sputtering faucets during a drought or gradually declining water pressure, recognizing the signs of a well running dry early gives you time to explore solutions before you're left completely without water. Here's what to watch for and what you can do about it.
Warning Signs Your Well May Be Running Dry
1. Sputtering Faucets and Air in the Lines
When your well's water level drops near the pump intake, it begins drawing air along with water. This creates:
- Sputtering or spitting when you first turn on faucets
- Bursts of air followed by water
- Uneven, pulsing water flow
- Loud gurgling sounds in pipes
Key indicator: If sputtering happens after heavy water use and improves after the well "rests," this strongly suggests low water level issues.
2. Muddy, Sandy, or Discolored Water
As water levels drop, your pump draws from closer to the bottom of the well where sediment accumulates:
- Sandy or gritty water: Pump is pulling from sediment zone
- Brown or muddy appearance: Disturbed bottom sediment
- Sudden change in water appearance: May indicate dramatic drop in water level
- Sediment in toilet tanks: Visible accumulation of sand or silt
Pump Damage Warning
Sand and sediment damage pump impellers and can cause premature pump failure. If you're seeing sediment, address the issue quickly to avoid expensive pump replacement.
3. Fluctuating or Declining Water Pressure
Pressure changes can indicate low well production:
- Pressure drops during use: Can't maintain pressure when multiple fixtures run
- Gradual pressure decline: Overall pressure lower than it used to be
- Recovery after rest: Pressure improves after well sits unused for hours
- Time-of-day patterns: Worse in summer or during irrigation season
4. Pump Runs Longer Than Normal
Your pump should run for a consistent time to fill the pressure tank. If it's running longer:
- Well can't supply water as fast as pump is trying to move it
- Pump is drawing from a diminishing column of water
- May run until it cycles off on thermal overload (dangerous)
- Electric bills may increase noticeably
5. Water Runs Out Completely
The most obvious sign—but by this point, you have an emergency:
- Faucets produce nothing or just air
- Pump runs continuously but no water comes out
- Pressure gauge reads zero
- May partially recover after several hours of non-use
6. Neighbors Having Similar Problems
Regional water table issues affect multiple properties:
- Nearby wells experiencing same symptoms
- Community discussion about drought impacts
- Local news reporting on groundwater levels
- New development or agriculture increasing regional water demand
What Causes Wells to Run Dry?
Drought and Climate Conditions
Extended dry periods are the most common cause of low well production in Southern California:
- Reduced rainfall means less aquifer recharge
- Multi-year droughts progressively lower water tables
- Summer demand peaks when water tables are lowest
- Climate change extending dry seasons
Increased Water Demand
- Personal usage increase: Irrigation, pool filling, additional family members
- Neighborhood development: More wells drawing from same aquifer
- Agricultural use: Farming operations depleting groundwater
- Municipal pumping: City wells impacting private well levels
Well Age and Condition
- Screen blockage: Mineral deposits or biofilm reducing water entry
- Silting in: Sediment accumulating at bottom, reducing effective depth
- Casing deterioration: Corrosion blocking water pathways
- Originally shallow: Well wasn't deep enough for long-term reliability
Pump Issues (Not Actually Dry)
Sometimes symptoms mimic a dry well but the actual problem is mechanical:
- Failing pump unable to produce normal flow
- Worn impellers reducing pump output
- Drop pipe leak causing pump to draw air
- Electrical issues affecting pump performance
Diagnosing the Problem
Professional Well Assessment
A proper diagnosis requires professional evaluation:
- Static water level measurement: How deep is water when pump isn't running
- Pumping water level: How far does water drop during pumping
- Recovery rate: How quickly does water level return after pumping stops
- Well capacity test: Gallons per minute the well can sustain
- Pump output test: Verify pump is performing to specification
What the Numbers Mean
- Low static level: Water table has dropped (aquifer depletion)
- Excessive drawdown: Well can't keep up with pump capacity
- Slow recovery: Aquifer has poor yield in your location
- Low pump output: Pump may be the problem, not the well
Solutions for a Well Running Dry
1. Lower the Pump
If there's water below the current pump position, lowering it can solve the problem:
When it works:
- Static water level has dropped but is still above current pump
- Well has additional depth below pump
- Seasonal drops that pump position can accommodate
Cost: $800-$2,000 (pulling pump, adding pipe, reinstalling)
Timeframe: Same day or next day service
2. Install a Water Storage Tank
A storage tank lets your well produce slowly around the clock while meeting peak demands:
How it works:
- Large tank (500-2,500+ gallons) stores water
- Well fills tank slowly over time
- Booster pump delivers water at normal pressure
- Tank provides reserve for high-demand periods
Cost: $3,000-$10,000 (tank, controls, booster pump)
Best for: Wells with adequate daily production but low instantaneous flow
3. Hydrofracturing (Well Deepening)
Hydrofracturing uses high-pressure water to open fractures in bedrock, improving water flow:
Process:
- Pump removed from well
- High-pressure water forced into rock formation
- Opens existing fractures and clears blockages
- Can improve yield significantly
Cost: $3,000-$8,000
Success rate: Improves yield in 70-80% of cases
Limitation: Only works in bedrock formations, not sand/gravel aquifers
4. Well Rehabilitation
Cleaning and restoring an existing well can recover lost production:
- Chemical treatment: Dissolves mineral buildup and biofilm
- Mechanical cleaning: Brushing and surging to clear screens
- Air development: Removing accumulated sediment
Cost: $2,000-$6,000
Best for: Older wells that have gradually lost production
5. Drill a New, Deeper Well
When other options won't work, a new well may be necessary:
When to consider:
- Current well is too shallow for regional water table
- Aquifer at current depth is depleted
- Well is old and rehabilitation isn't cost-effective
- Need significantly more water than current well can provide
Cost: $15,000-$50,000+ depending on depth
Timeframe: 1-4 weeks for permitting and drilling
6. Reduce Water Usage
Sometimes the most practical solution is reducing demand:
- Install water-efficient fixtures and appliances
- Switch to drip irrigation for landscaping
- Reduce or eliminate lawn irrigation
- Spread out heavy water use throughout the day
- Consider drought-tolerant landscaping
Emergency Measures When Water Runs Out
If you're completely out of water:
- Stop trying to run the pump: Running dry damages the motor
- Order water delivery: Tank truck can fill a storage tank
- Contact neighbors: Temporary water sharing may be possible
- Call a well professional: Emergency diagnosis and temporary solutions
- Document everything: For insurance purposes if applicable
When to Call a Professional
Contact a well service professional when:
- You notice any of the warning signs listed above
- Water production has noticeably decreased
- You're seeing sand or sediment in your water
- Pump runs longer than it used to
- You've completely run out of water
- You want a proactive assessment before problems worsen

Frequently Asked Questions
How can I tell if my well is running dry?
Common signs include sputtering or air in faucets, muddy or sandy water, reduced water pressure that recovers after non-use, pump running longer than normal, and water running out completely after heavy use. These symptoms often worsen during drought or high-use periods like summer.
Can a well that went dry come back?
Yes, in many cases. If the well went dry due to drought or seasonal low water tables, it often recovers when rainfall replenishes the aquifer. However, if the aquifer is permanently depleted or the well has structural issues, recovery may not occur without intervention like deepening the well or drilling a new one.
How much does it cost to fix a dry well?
Costs vary by solution: Lowering the pump costs $800-$2,000. Well deepening (hydrofracturing) runs $3,000-$8,000. Drilling a new deeper well costs $15,000-$50,000+ depending on depth. Installing a water storage tank system costs $3,000-$10,000. A professional assessment is needed to determine the best option.
How do I prevent my well from running dry?
Monitor your water usage and well performance, especially during dry seasons. Spread out heavy water use rather than using large amounts at once. Consider installing a storage tank to buffer demand. Get regular well inspections to catch problems early. During drought, implement water conservation measures.
