- Hard rock formations
- Deep drilling required
- Total: 6-8+ weeks
Permit Phase
San Diego County
- Application processing: 2-3 weeks typical
- Online permit available
- Requires parcel info, site plan
- Health department review
Riverside County
- Similar timeline: 2-4 weeks
- EH department issues permits
What Can Delay Permits
- Incomplete applications
- Additional requirements (setbacks, etc.)
- Agency backlog
- CEQA review in some areas
Expediting Tips
- Complete, accurate application
- Have all documents ready
- Use experienced driller (knows process)

Drilling Phase
Day-of Drilling
| Well Depth | Typical Drilling Time |
|---|---|
| 0-100 feet | 1/2 - 1 day |
| 100-300 feet | 1-2 days |
| 300-500 feet | 2-3 days |
| 500+ feet | 3+ days |
What Affects Drilling Speed
Formation Type
- Soft formations: Fast (100+ feet/day)
- Fractured rock: Medium (50-100 ft/day)
- Hard granite: Slow (30-50 ft/day)
Other Factors
- Equipment type (air rotary vs cable tool)
- Site access
- Water-bearing zones encountered
- Casing requirements
What Happens Each Day
Day 1
- Rig setup
- Begin drilling
- Set surface casing if needed
Day 2+ (if needed)
- Continue drilling
- Note water-bearing zones
- Reach target depth or adequate water
Completion Phase
Well Development
- Clears fine material from well
- Improves water flow
- 1-2 days typical
- Includes flow testing
Pump Installation
- Select pump based on well specs
- Install submersible pump
- Connect electrical
- Install pressure tank
- Test system
- 1-2 days typical
Well Completion Report
- Required by county
- Documents depth, casing, yield
- Filed with state DWR
Water Testing (Optional but Recommended)
- Sample collected
- Lab results: 1-2 weeks
- Tests bacteria, minerals, etc.
Final Steps
- System walkthrough
- Paperwork finalized
- Well cap/seal installed
- Site cleanup
Frequently Asked Questions
How long does it take to drill a well?
Total process: 2-8 weeks. Actual drilling: 1-3 days. Permit waiting is usually longest part.
What affects well drilling time?
Permit processing, rock formations, depth, site access, contractor availability, and weather.
Can drilling be done in one day?
Yes, for shallow wells in easy formations. Deep wells or hard rock take longer.
What's the fastest I can get water?
Best case: 2-3 weeks if permit comes quickly and geology cooperates.
Why is my permit taking so long?
County workload, incomplete application, or additional requirements. Follow up politely.
Can you drill in any weather?
Rain can delay work. Need site access and safe conditions. Extreme cold affects some operations.
