San Diego's East County backcountry — Jamul, Alpine, Dulzura, Campo, and Potrero — is prime territory for rural living. No municipal water means private wells are essential. Here's what property owners in these areas need to know.

Local Geology

East County sits on the Peninsular Range batholith — primarily granitic rock with some metamorphic formations:

What This Means for Wells

  • Fractured rock aquifers: Water flows through cracks in granite, not sand/gravel
  • Variable yields: Depends on hitting good fracture zones
  • Air rotary drilling: Required for hard rock
  • Unpredictable depths: Neighboring properties can vary significantly

Typical Well Depths

Area Typical Range Average
Jamul 200-450 feet 300 feet
Alpine 250-500 feet 350 feet
Dulzura 200-400 feet 280 feet
Campo/Potrero 250-500 feet 350 feet

Expected Yields

Backcountry wells typically produce:

  • Good: 10-20+ GPM (above average for granite)
  • Average: 5-10 GPM (adequate for most homes)
  • Marginal: 2-5 GPM (needs storage tank)
  • Poor: Under 2 GPM (may need to drill deeper)

Many properties in this region have wells producing 5-8 GPM — workable with proper system design.

Cost Expectations

Component Cost Range
Drilling (per foot) $45-$70
Average 300 ft well $13,500-$21,000
Pump system $3,000-$6,000
Storage tank (if needed) $3,000-$8,000
Total typical $20,000-$35,000

Special Considerations

Fire Season

East County is high fire risk. Consider:

  • Storage tanks provide emergency water supply
  • Generator backup keeps pump running during power shutoffs
  • Fire department access to your water source

Power Outages

PSPS (Public Safety Power Shutoffs) are common in backcountry. A generator or solar+battery system is strongly recommended.

Access for Drilling

Remote properties may have access challenges. We have equipment for most situations, but steep or narrow roads may require site prep.

Horse Properties

Many Jamul and Alpine properties have horses. Plan for 10-15 gallons per horse per day in addition to household needs. See our horse property guide.

Water Quality

Backcountry groundwater is generally good quality:

  • Low TDS: Typically 200-500 ppm
  • Moderate hardness: May want softener for indoor use
  • Low iron: Usually not a problem
  • Test annually: For bacteria, especially after wet winters
