Your Complete Guide to Residential Well Drilling

Benefits of a Residential Water Well
💰 Eliminate Water Bills
San Diego County water rates average $80-150/month and rising annually. A well typically pays for itself in 10-15 years through savings, then provides essentially free water for decades.
🏠 Water Independence
No water restrictions, rate increases, or supply concerns. Your well provides reliable water on your schedule, not the water district's.
📈 Property Value
A well-maintained private well adds $10,000-$30,000 to property value, especially in rural San Diego areas where water rights are increasingly valuable.
💧 Quality Control
Know exactly what's in your water. Well water avoids chlorine and fluoride added to city water, though you control any treatment based on your needs.
Residential Well Drilling Process
Our comprehensive residential well drilling process ensures you get a reliable, long-lasting water supply:
1. Site Assessment & Consultation
We evaluate your property, review geological data, check existing well logs in your area, and identify the optimal drilling location. We discuss your water needs, expected depth, and provide a detailed estimate.
2. Permit Application
We handle San Diego County permit applications, including required setbacks from septic systems (100 feet), property lines (50 feet), and other structures. Permit approval typically takes 2-4 weeks.
3. Drilling
Using rotary or air drilling equipment appropriate for your geology, we drill to the target depth. San Diego residential wells typically range from 150-500 feet. We monitor for water-bearing formations throughout the process.
4. Casing & Grouting
Steel or PVC casing protects your well and prevents surface contamination. The annular space between the casing and borehole is grouted with cement to create a sanitary seal.
5. Development & Yield Testing
We develop the well to maximize water production and conduct yield testing to determine sustainable flow rate (GPM). This data ensures proper pump sizing.
6. Pump System Installation
We install a submersible pump sized to your well's depth and yield, plus pressure tank, pressure switch, and electrical connections. Systems are configured for optimal pressure (40-60 PSI typical).
7. Water Quality Testing
We test for bacteria, minerals, pH, and other parameters. If treatment is needed (iron removal, softening, UV disinfection), we recommend and install appropriate systems.

Frequently Asked Questions
How much does it cost to drill a residential well in San Diego?
Residential well drilling in San Diego County typically costs $15,000 to $50,000 for a complete system. This includes drilling ($35-75 per foot), casing, grout seal, submersible pump ($1,500-$4,000), pressure tank ($300-$800), electrical connections, and permits ($500-$1,500). Average well depth is 200-400 feet, though some areas require 500+ feet.
How long does it take to drill a residential well?
The drilling itself takes 1-3 days for most residential wells. However, the complete process from permit application to finished well typically takes 4-8 weeks. San Diego County permits can take 2-4 weeks to obtain. After drilling, pump installation, electrical work, and water testing add another 2-5 days.
How deep does a residential well need to be in San Diego?
Residential wells in San Diego County typically range from 150 to 500 feet deep, depending on location. Coastal areas may find water at 100-200 feet, while mountain communities like Julian, Ramona, and Alpine often require 300-500+ feet. A professional site assessment using geological data helps predict depth before drilling begins.
Do I need a permit to drill a residential well in California?
Yes, California requires permits for all new wells. San Diego County issues permits through the Department of Environmental Health. Requirements include a completed application, site map, setback compliance (50-100 feet from septic systems), and fees ($500-$1,500). Your well contractor typically handles permit applications as part of the service.
How much water does a residential well produce?
Most residential wells produce 3-10 gallons per minute (GPM). A minimum of 3 GPM is recommended for a typical household, while 5-7 GPM handles most families comfortably. San Diego wells vary widely—some produce 15+ GPM while others yield 1-2 GPM and require storage tanks. A yield test determines your well's capacity.
