- Don't Wait Until Fire Season—Prepare Your Well Now
When power goes out during wildfires, your well stops working. No electricity = no water for firefighting, drinking, or property defense. Emergency preparation isn't optional—it could save your property and your life.
California's wildfire season grows longer and more intense each year. If you depend on a well for water, you face a unique challenge: when the power fails, so does your water supply. This comprehensive guide helps well owners in San Diego, Riverside, and San Bernardino counties prepare for fire season.
Understanding the Fire-Power-Water Connection
The sequence is predictable and dangerous: wildfires approach, power companies implement public safety power shutoffs (PSPS), or fires damage electrical infrastructure. Either way, the power fails. Your well pump requires electricity. Without power, you have zero water access until power restoration—which can take days or weeks.
This creates a cascading emergency:
- No water for firefighting or property defense
- No drinking water or sanitation
- No water for livestock or crops
- Increased vulnerability when evacuation isn't yet ordered but fire approaches
- No ability to wet down structures or create defensible space
Why Well Owners Face Higher Risk
Municipal water systems have backup generators and redundant power feeds. Your private well doesn't. Rural areas with wells are often:
- Located in high fire hazard zones
- Far from fire hydrants and municipal water
- At the end of long power distribution lines (first to lose power, last to restore)
- In areas where PSPS shutoffs are most common
- Surrounded by vegetation that increases fire risk
Emergency Power Solutions for Your Well
Portable Generators
Best for: Most homeowners seeking affordable backup power.
A quality portable generator (7,500-10,000 watts) can run your well pump and essential appliances during outages. Here's what you need to know:
Generator Sizing Guide
- Shallow wells (0-100 ft): 3,000-5,000 watts
- Medium wells (100-300 ft): 5,000-7,500 watts
- Deep wells (300+ ft): 7,500-10,000+ watts
- Agricultural/high-capacity pumps: 10,000-15,000+ watts
Critical generator requirements:
- Transfer switch installed by licensed electrician (prevents backfeeding danger)
- Outdoor placement only (carbon monoxide risk)
- Minimum 20 feet from windows, doors, and vents
- Fuel storage: 15-20 gallons minimum (5-7 days of runtime)
- Regular maintenance and test runs (monthly recommended)
Automatic Standby Generators
Best for: Property owners who need guaranteed power without manual intervention.
Permanently installed standby generators automatically detect power loss and start within 10-30 seconds. They run on natural gas or propane, eliminating fuel storage concerns.
Advantages:
- Automatic operation—power restores even if you're away
- No fuel cans to store or manage
- Weekly self-testing maintains readiness
- Larger capacity (10kW-48kW typical)
- Can power entire home plus well
Considerations:
- Higher upfront cost ($5,000-$15,000 installed)
- Requires propane tank or natural gas service
- Annual professional maintenance recommended
- Permits and professional installation required
Solar + Battery Systems
Modern solar installations with battery backup (like Tesla Powerwall or similar) can run well pumps during extended outages—especially valuable during multi-day PSPS events.
Ideal for:
- Properties already considering solar installation
- Areas with frequent PSPS events
- Long-term cost reduction goals
- Environmental priorities
Battery systems typically store 10-15kWh, enough to run a well pump intermittently for several days while solar panels recharge the batteries during daylight.
Water Storage Strategies
Dedicated Fire Protection Storage
Cal Fire recommends 2,500 gallons minimum for structure defense. Larger properties should consider 5,000-10,000 gallons. Options include:
- Above-ground tanks: Polyethylene or steel tanks (500-10,000 gallons)
- Underground cisterns: Concrete or fiberglass (1,000-20,000+ gallons)
- Swimming pools: Can serve dual purpose with proper pump setup
- Agricultural tanks: Repurposed for fire defense
Pro Tip: Gravity-Fed Systems
Elevate storage tanks above your property to create gravity-fed pressure. A tank positioned 50 feet higher than your home provides approximately 21 PSI—enough for basic firefighting and domestic use without pumps or power.
Emergency Drinking Water
Store separately from firefighting water:
- Minimum: 1 gallon per person per day Ă— 14 days
- Recommended: 30-day supply for extended outages
- Food-grade containers only (5-gallon jugs, water bricks, 55-gallon drums)
- Rotation schedule: Replace every 6-12 months
- Treatment: Add water preservative or household bleach (8 drops per gallon)
Well System Hardening
Protect Your Wellhead
Your wellhead is the most vulnerable component during wildfires. Implement these protections:
- Clear 30-foot defensible space around wellhead (100 feet ideal)
- Remove all combustible materials within 10 feet
- Verify wellhead seal integrity—damaged seals allow ash/debris entry
- Install fire-resistant well house if exposed equipment present
- Protect above-ground wiring with metal conduit
- Mark wellhead location clearly for firefighters
Pressure Tank Maintenance
Your pressure tank provides immediate water access when power fails—but only if properly maintained:
- Check pressure regularly: Should be 2 PSI below pump cut-in pressure
- Verify tank capacity: A 40-gallon tank stores ~10 gallons usable water
- Test draw-down: How long does water last with power off?
- Consider upgrading: Larger tanks (80-120 gallons) provide extended emergency supply
Equipment Inspection Checklist
Before fire season (April-May each year), inspect:
- Pump operation and water flow
- Electrical connections and wiring condition
- Pressure switch function and settings
- Pressure tank charge and bladder condition
- Control panel and circuit breaker operation
- Generator connection and transfer switch
- All valves for operation and leaks
- Water quality (test if contamination suspected)
Regional Fire Season Considerations
San Diego County
Fire season peaks during Santa Ana wind events (October-December) and summer heat waves. High-risk areas include:
- Ramona and Santa Ysabel (historic Cedar Fire, 2003)
- Alpine and Harbison Canyon (Harris Fire, 2007)
- Valley Center and Pauma Valley
- Julian and surrounding mountain communities
- Lakeside and El Cajon backcountry
SDG&E implements PSPS during extreme fire weather—often with 12-48 hours advance notice.
Riverside County
Extended fire season due to diverse climate zones. Key concerns:
- Santa Ana winds funnel through passes near Banning and Beaumont
- Desert communities face extreme summer heat (Thermal, Coachella Valley)
- Mountain areas (Idyllwild, Anza) experience longer fire seasons at elevation
- Southwest county (Temecula, Murrieta) shares San Diego weather patterns
San Bernardino County
Largest county in California faces varied fire threats:
- Mountain communities (Big Bear, Lake Arrowhead, Running Springs) vulnerable to forest fires
- High Desert (Victorville, Hesperia, Apple Valley) faces grassland fires spreading rapidly
- Urban-wildland interface expanding throughout Inland Empire
- Extended PSPS events common in mountain and rural areas
Emergency Response Planning
Create Your Well Emergency Kit
Maintain these supplies in accessible location:
- Generator fuel: 15-20 gallons fresh gasoline (rotate every 3-6 months)
- Fuel stabilizer: Extends storage life to 12-24 months
- Extra oil: For generator maintenance
- Transfer switch key or tools for manual changeover
- Spare fuses and circuit breakers for well system
- Pump pressure gauge for diagnostics
- Emergency contact list: Well service, electrician, generator service
- Well system documentation: Pump specs, wiring diagram, service history
72-Hour Action Plan
When fire danger escalates or PSPS announced:
Immediately:
- Fill all storage tanks to capacity
- Fill bathtubs and sinks with water
- Fill every available container (pots, buckets, coolers)
- Test generator operation and fuel availability
- Charge all electronics and backup batteries
24 hours before predicted power loss:
- Position generator in safe operating location
- Connect transfer switch and test well operation
- Set up irrigation/sprinkler system for property defense
- Clear combustibles from around wellhead and generator
- Document all equipment serial numbers and settings
When power fails:
- Start generator following manufacturer procedures
- Monitor fuel consumption and plan refueling schedule
- Conserve water—use stored water for non-essential needs
- Never run generator indoors or in enclosed spaces
- Maintain 6-hour runtime then 30-minute cool-down cycle
Post-Fire Well Safety
After nearby wildfires, even if your property wasn't directly burned:
- Inspect wellhead for damage—heat can crack seals and casings
- Check for ash or debris around wellhead
- Test water quality before consumption—especially for shallow wells
- Watch for changes in taste, odor, or color
- Run water for 30 minutes before use if well was exposed to smoke/heat
- Professional inspection recommended if fire came within 1/4 mile

Frequently Asked Questions
When is California's fire season?
California's traditional fire season runs from May through October, but climate change has extended it year-round in many areas. Peak danger typically occurs during hot, dry periods with Santa Ana winds (October-November) and during extreme heat events in summer months.
Will my well work during a power outage caused by wildfires?
No. Well pumps require electricity to operate. During power outages, you'll have no water unless you have backup power (generator or battery system) or stored water. This makes emergency preparation critical for well owners in fire-prone areas.
What size generator do I need to run my well pump?
Most residential well pumps require 3,000-5,000 watts to start and 1,500-2,500 watts to run. A 7,500-watt portable generator typically handles most home wells. For deep wells or high-capacity pumps, you may need 10,000+ watts. Always check your pump's nameplate for exact requirements.
How much water should I store for fire emergencies?
Cal Fire recommends 2,500 gallons minimum for structure defense. For drinking and sanitation, store at least 1 gallon per person per day for 7-14 days. Well owners should maintain pressure tanks in good condition and consider installing a larger storage tank with gravity-fed access.
Can wildfire smoke contaminate my well water?
Deep wells are generally protected from smoke contamination, but ash and debris can enter shallow wells or wells with damaged wellheads. Surface runoff after fires can introduce contaminants. Test your water after any nearby wildfire, especially if you notice changes in taste, smell, or appearance.
