Preparing Your Well for Drought
Drought is an inevitable reality for California well owners. Whether you're experiencing declining water levels now or preparing for the next dry cycle, taking proactive steps today can prevent water emergencies tomorrow. This comprehensive guide covers everything you need to know about drought-proofing your well—from early warning signs to backup systems and conservation strategies.
⚡ Drought Preparation Priority Checklist
- • Establish baseline static water level measurements
- • Have your well professionally inspected
- • Fix all leaks and install low-flow fixtures
- • Consider adding water storage capacity
- • Review and optimize irrigation systems
- • Know your backup options before you need them
Understanding Drought and Your Well
Private wells draw from groundwater aquifers that are recharged primarily through rainfall and snowmelt. During extended dry periods, these aquifers receive less recharge while demand often increases—a combination that can cause water levels to drop significantly.
How Drought Affects Wells
The impact of drought on your well depends on several factors:
- Well depth: Deeper wells generally have more buffer against drought
- Aquifer type: Bedrock aquifers respond differently than alluvial aquifers
- Regional usage: Neighboring wells and agricultural pumping affect local water tables
- Well yield: Low-yield wells are more vulnerable than high-yield wells
- Static water level: How much water sits above your pump intake
📉 How Drought Impacts Progress Over Time
Year 1 of Drought
Early Warning Signs
Slightly longer pump run times, subtle pressure changes during peak use
Year 2-3 of Drought
Noticeable Decline
Reduced flow rates, air in lines during heavy use, water quality changes
Extended Drought
Critical Conditions
Well running dry during peak demand, pump damage risk, emergency situations
Early Warning Signs Your Well Is Affected
Catching problems early gives you time to respond before you're in crisis mode. Watch for these warning signs:
Physical Signs
⚠️ Declining Water Pressure
Noticeable drop from previous normal, especially during peak use times
⚠️ Air Spurting From Faucets
Indicates pump is pulling air as water level approaches intake
⚠️ Sandy or Silty Water
Lower water levels can disturb sediment at the bottom of the well
⚠️ Longer Pump Run Times
Pump working harder to maintain pressure or fill storage
⚠️ Short Cycling
Pump turns on and off frequently—may indicate well recovery issues
⚠️ Water Quality Changes
Taste, odor, or color changes may indicate dropping water levels
If you're experiencing any of these issues, see our guide on what to do when your well has no water.
Step 1: Know Your Well's Baseline
You can't manage what you don't measure. Establishing baseline data about your well is the foundation of drought preparation.
Critical Measurements to Track
Static Water Level
The depth from the surface to the water when the pump hasn't run for several hours. This is your most important drought indicator.
- Measure monthly during normal conditions
- Measure weekly during drought
- Always measure at the same time of day
- Record date, time, and recent usage before measurement
Pumping (Dynamic) Water Level
The depth to water while the pump is running. The difference between static and pumping levels indicates well yield.
- Measure after pump has run for 15-30 minutes
- Greater drawdown during drought indicates declining yield
Well Recovery Rate
How quickly the water level returns to static after pumping stops. Slower recovery = less water available.
📊 Pro Tip: Keep a Well Log
Create a simple spreadsheet tracking: date, static water level, any issues noticed, and monthly water usage. This data is invaluable for identifying trends and making informed decisions about your well.
Review Your Well Records
Gather and review these documents if available:
- Well completion report: Shows original well depth, casing details, and initial yield
- Well log: Describes geological formations penetrated
- Pump specifications: Pump depth, flow rate, horsepower
- Previous service records: Any past issues or modifications
Don't have these records? A professional well inspection can establish your current baseline and identify potential concerns.
Step 2: Professional Well Assessment
A professional evaluation before drought conditions worsen gives you time to plan and budget for any needed improvements.
What a Drought-Readiness Assessment Includes
| Assessment Component | What It Reveals |
|---|---|
| Static Water Level Measurement | Current groundwater level and available buffer |
| Well Yield Test | How much water your well can sustainably produce |
| Pump Performance Check | Whether pump is operating efficiently |
| Video Inspection | Casing condition, screen integrity, obstructions |
| Water Quality Test | Baseline quality for comparison if levels drop |
| System Review | Pressure tank, controls, and overall system health |
Potential Improvement Options
Based on the assessment, your well professional may recommend:
- Lowering the pump: If there's room, positioning the pump deeper provides more buffer
- Well rehabilitation: Cleaning and developing the well can restore lost capacity
- Well deepening: Extending your well into deeper aquifers
- Hydrofracturing: Creating new water channels in bedrock wells
- Storage addition: Installing tanks to buffer against temporary shortages
Step 3: Water Conservation Strategies
Conservation is your first line of defense. Reducing demand extends your water supply and puts less stress on your well and aquifer.
Indoor Conservation
🚿 Low-Flow Fixtures
WaterSense toilets (1.28 gpf), showerheads (2.0 gpm), and faucet aerators can reduce indoor use 20-30%
🔧 Fix All Leaks
A dripping faucet wastes 5+ gallons/day; a running toilet can waste 200 gallons/day
🧺 Efficient Appliances
High-efficiency washers use 15-30 gallons vs. 40+ gallons for older models
🍽️ Smart Water Habits
Only run full loads, don't pre-rinse dishes, take shorter showers
Outdoor Conservation
Outdoor irrigation typically accounts for 50-70% of residential water use—this is where the biggest savings are possible.
🌱 Drought-Tolerant Landscaping
Native plants, xeriscaping, and removing thirsty lawns can cut outdoor use 50%+
💧 Drip Irrigation
90% efficient vs. 50-70% for sprinklers; delivers water directly to roots
🎛️ Smart Controllers
Weather-based controllers adjust watering based on conditions, saving 20-30%
⏰ Water at Right Times
Early morning (4-9 AM) reduces evaporation; never water midday or during wind
Leak Detection
Even small leaks waste significant water. Here's how to find them:
Meter Test for Hidden Leaks
- Turn off all water-using appliances and fixtures
- Record your water meter reading
- Wait 2 hours without using any water
- Check meter again—if it's moved, you have a leak
No meter? Monitor your pressure tank cycles. If the pump runs when nothing is being used, you have a leak.
Step 4: Increase Water Storage
Adding storage capacity is one of the most effective drought preparations. Storage tanks allow your well to pump slowly around the clock, accumulating water for peak demand periods.
Storage Tank Benefits During Drought
- Buffer against low yield: Even a 1 GPM well can fill a 1,400-gallon tank overnight
- Allows well recovery: Pump cycles with rest periods instead of continuous running
- Emergency reserve: Water available if well temporarily fails
- Fire protection: Many insurance companies offer discounts for adequate storage
- Reduces pump stress: Fewer on/off cycles extend pump life

Storage System Components
A complete storage system includes:
- Storage tank: Poly or concrete, above or below ground
- Float switch: Controls well pump based on tank level
- Booster pump: Delivers water from tank to house at proper pressure
- Pressure tank: Maintains consistent delivery pressure
- Check valves: Prevent backflow
- Low-level cutoff: Protects booster pump from running dry

Step 5: Consider Well Modifications
If your well is showing drought stress, several modifications can improve its resilience:
Lowering the Pump
If your well is deeper than your current pump setting, lowering the pump provides more water buffer above the intake.
Typical cost: $500 - $1,500
Requirements: Sufficient well depth below current pump, adequate water quality at deeper level
Considerations: May require longer electrical cable and drop pipe
Well Deepening
Extending your well into deeper formations can access additional water. This is often more economical than drilling a new well.
Typical cost: $50 - $100 per foot plus casing
Requirements: Existing casing in good condition, deeper aquifer formations present
Success factors: Review of well logs from deeper wells in your area
Hydrofracturing
For bedrock wells, hydrofracturing uses high-pressure water to open and connect fractures, potentially increasing yield.
Typical cost: $1,500 - $3,500
Best for: Granite, gneiss, and other hard rock wells
Success rate: Improves yield in approximately 70-80% of suitable wells
Well Rehabilitation
Over time, wells can become clogged with mineral deposits, bacteria, or sediment. Professional rehabilitation can restore lost capacity.
Typical cost: $1,000 - $3,000
Methods: Chemical treatment, mechanical cleaning, surging, air lifting
Best for: Wells with declining yield over time, not just drought
Step 6: Develop Backup Water Plans
Even with the best preparation, severe droughts can overwhelm any well. Having backup plans provides peace of mind.
Backup Options Comparison
| Option | Pros | Cons | Cost Range |
|---|---|---|---|
| Second Well | Permanent solution, may tap different aquifer | High upfront cost, no guarantee of success | $15,000-$40,000 |
| Municipal Connection | Reliable backup, can be used as supplement | Not available in all areas, connection fees | $3,000-$15,000 |
| Hauled Water | No infrastructure needed, flexible | Ongoing cost, requires storage tank | $200-$400/load |
| Rainwater Harvesting | Sustainable, reduces well dependence | Unreliable during drought, storage needed | $5,000-$15,000 |
| Greywater Recycling | Reduces well demand for irrigation | Regulatory requirements, maintenance | $2,000-$8,000 |
Emergency Water Hauling
Know your local water hauling options before you need them:
- Research and save contact information for 2-3 water hauling companies
- Confirm they serve your area and understand delivery logistics
- Ensure you have adequate storage tank capacity (minimum 2,500 gallons recommended)
- Know the access requirements—can a water truck reach your tank?
Special Considerations for California Well Owners
SGMA and Groundwater Management
California's Sustainable Groundwater Management Act (SGMA) is bringing changes to groundwater use in critically overdrafted basins. While most private domestic wells are currently exempt from metering and allocation requirements, this may change. Stay informed about:
- Your local Groundwater Sustainability Agency (GSA)
- Basin sustainability plans and timelines
- Potential future pumping limitations
- Well registration requirements
Regional Considerations
San Diego and Riverside County areas have varying drought vulnerability:
- Coastal valleys: Generally more stable aquifers with higher recharge
- Inland valleys (Ramona, Valley Center): Moderate vulnerability, decomposed granite aquifers
- Mountain areas (Julian, Palomar): Fractured rock aquifers, highly variable
- Desert fringe (Borrego Springs, Anza): Most vulnerable, limited recharge
