Water Well Drilling Cost Per Foot
Drilling is the largest cost component. Per-foot rates vary by geology:
| Geology | Cost/Foot | Notes |
|---|---|---|
| Sand/Gravel | $25-$35 | Fastest drilling, lowest cost |
| Clay/Sediment | $30-$45 | Common in valleys |
| Decomposed Granite | $35-$55 | Common in San Diego inland |
| Soft Rock | $40-$55 | Sandstone, limestone |
| Hard Rock/Granite | $50-$75 | Slowest, most expensive |
Note: Per-foot rates cover drilling labor and basic materials. Casing, pump, and installation are additional costs.
Total Water Well Project Costs
A complete water well includes much more than drilling:

What Affects Your Water Well Drilling Cost
1. Required Depth
The #1 cost driver. Every 50 feet adds $1,500-$4,000 to your total.
2. Geology
Hard rock costs nearly double soft formations. Your contractor can estimate geology from area well logs.
3. Well Diameter
- 4-inch: Standard residential, lower cost
- 6-inch: Higher flow capacity, 20-30% more
4. Pump Selection
- Budget (Flotec): $1,200-$1,800 installed
- Standard (Franklin): $1,800-$2,800 installed
- Premium (Grundfos): $2,800-$4,500 installed
5. Site Access
Difficult access adds $500-$5,000 for road building, equipment positioning, or water hauling.
6. Location/County
Permit fees range from $500 in rural areas to $1,500+ in some jurisdictions.
Drilling Costs by County
San Diego County
Most variable geology. Expect 150-350 feet typical depth.
- Coastal (La Jolla to Carlsbad): $12,000-$25,000
- Inland (Escondido, Ramona): $18,000-$35,000
- Mountains (Julian, Palomar): $25,000-$50,000
Riverside County
Valley floors often easier; mountains challenging.
- Southwest (Temecula, Murrieta): $15,000-$30,000
- Hemet/San Jacinto: $18,000-$35,000
- Anza/Idyllwild: $22,000-$45,000
San Bernardino County
High desert typically requires deep drilling.
- Yucaipa/Mentone: $18,000-$35,000
- Apple Valley/Hesperia: $30,000-$55,000
Getting Accurate Quotes
What to Ask
- What's the estimated depth for my property?
- What's included in the quote?
- What's NOT included?
- What happens if you need to go deeper?
- What's the dry hole policy?
- Are permits included?
- What's the warranty?
Red Flags
- Quote significantly below competitors
- No written estimate
- Large deposit demanded upfront
- No C-57 license verification
- Guarantees specific depth or yield
Getting Multiple Quotes
Always get 3+ quotes. Compare line items, not just totals. The cheapest quote often excludes essentials.
Is Drilling a Well Worth It? Cost vs. City Water
Wells typically pay for themselves in 10-15 years through water bill savings. Here's the math:
Monthly City Water Costs
- Average household: $50-$100/month
- With irrigation: $100-$300/month
- Large property: $200-$500/month
Well Water Costs
- Electricity: $20-$50/month
- Maintenance: $200-$500/year
- Pump replacement: $1,500-$3,500 every 15-20 years
Breakeven Example
If you're paying $150/month for city water and your well costs $20,000:
- Annual savings: ~$150/month × 12 = $1,800
- Minus electricity: ~$1,450/year net savings
- Breakeven: 13-14 years
For properties with high water use (irrigation, livestock, multiple homes), breakeven can be 5-8 years.
Financing Your Water Well
Several options exist for financing well drilling:
Common Financing Options
- Home equity loan: Lowest rates, tax-deductible interest
- Personal loan: No collateral required, quick approval
- USDA Rural Development: Low-interest loans for qualifying properties
- FHA 203(k): Can include well in home purchase/renovation loan
- Contractor financing: Some drillers offer payment plans
Tax Considerations
Wells for primary residences may qualify as capital improvements, potentially increasing your home's cost basis. Consult a tax professional for your specific situation.
Money-Saving Tips
Before You Hire
- Check well logs: Free public records show neighbor well depths and yields
- Get multiple quotes: Prices vary 20-40% for same work
- Time it right: Fall/winter may have lower prices (slower season)
- Bundle permits: Some contractors include, others charge extra
During Drilling
- Be present: Discuss decisions in real-time
- Stop at adequate yield: Don't drill deeper than needed
- Choose appropriate pump: Don't overbuy capacity
What NOT to Cheap Out On
- Casing quality: Cheap casing = short well life
- Pump brand: Quality pumps last 15-20 years vs. 8-12 for budget
- Proper sealing: Prevents contamination
Frequently Asked Questions
How much does water well drilling cost?
$25-$65 per foot for drilling, with complete projects costing $5,000-$50,000+. Most residential wells in Southern California cost $15,000-$35,000 including pump and installation.
What is the price per foot to drill a water well?
$25-$65 per foot depending on geology. Sand costs $25-$35/foot, hard rock costs $50-$75/foot.
How much does a 200 foot water well cost?
A 200-foot well typically costs $15,000-$28,000 complete including drilling, casing, pump, electrical, and permits.
How long does water well drilling take?
1-3 days for drilling. 2-4 weeks for the complete project including permits and installation.
Is drilling a water well worth it?
Usually yes for rural properties. Wells eliminate monthly water bills and typically pay for themselves in 10-15 years through savings.
Do I need a permit to drill a water well?
Yes, permits are required in all California counties. Costs range from $500-$1,500 depending on location and complexity.
What happens if the driller doesn't find water?
Most drillers charge for actual work completed (dry hole rates). Some offer reduced rates for dry holes. Always discuss this before signing a contract.
Can I drill my own water well?
Not legally in California. Well drilling requires a C-57 contractor license due to groundwater protection regulations.
How deep is the average residential well?
In Southern California, residential wells average 150-300 feet. Coastal areas may be shallower (100-200 ft), while mountain areas may require 400+ feet.
Does a deeper well mean better water quality?
Often yes, but not always. Deeper wells access older, more filtered groundwater. However, some deep formations have mineral issues. Testing determines quality regardless of depth.
