What Does a Water Drilling Company Do?
A professional water drilling company provides comprehensive services related to water well construction and maintenance. Here's what you can expect:
New Well Drilling
The primary service of any water drilling company is drilling new water wells. This complex process involves:
- Site evaluation to determine the best drilling location based on geology, setbacks, and access
- Permit acquisition through county health departments and other agencies
- Drilling operations using specialized rigs and techniques matched to local geology
- Casing installation to protect the wellbore and prevent contamination
- Sanitary sealing (grouting) to seal the space between the casing and formation
- Well development to maximize water production from the aquifer
- Flow testing to determine the well's production capacity
Well Pump Systems
A water drilling company installs complete pump systems to deliver water to your home:
- Submersible pump selection and installation based on well depth and water needs
- Pressure tank sizing and installation for consistent water pressure
- Control systems including pressure switches and control boxes
- Electrical connections from the main panel to the well
- Piping from the well to your home's plumbing system

Well Maintenance and Repair
Beyond new drilling, water drilling companies provide ongoing services:
- Pump repair and replacement when equipment fails
- Pressure tank service including replacement of waterlogged tanks
- Well rehabilitation to restore production to declining wells
- Well deepening when water levels drop
- Water quality testing and treatment solutions
- Emergency service when you lose water unexpectedly
Types of Wells
Professional water drilling companies can drill various well types:
- Residential wells for single-family homes (most common)
- Agricultural wells for irrigation and livestock
- Commercial wells for businesses and developments
- Community wells serving multiple properties
Each type has different requirements for production rates, casing sizes, and pump systems.
How to Choose a Water Drilling Company
Selecting the right water drilling company requires careful evaluation. Here's what to look for:
Verify Licensing
In California, water drilling requires a C-57 Water Well Contractor license. This is non-negotiable:
- Visit the California Contractors State License Board (CSLB)
- Search by company name or license number
- Verify the license is active and includes C-57 classification
- Check for any complaints or disciplinary actions
- Confirm workers' compensation insurance is current
⚠️ Warning: Hiring an unlicensed water drilling company is illegal in California and puts your investment at risk. Unlicensed work may not pass inspection, void warranties, create liability for groundwater contamination, and make it difficult to sell your property later.
Check Insurance Coverage
A reputable water drilling company carries adequate insurance:
- General liability insurance (minimum $1 million recommended)
- Workers' compensation covering all employees
- Equipment insurance for the drilling rig and tools
Request certificates of insurance and verify they're current before work begins.
Evaluate Experience
Experience matters, especially local experience:
- How long has the company been in business?
- How many wells have they drilled in your specific area?
- Do they understand the local geology and typical depths?
- Are they familiar with local permit requirements?
- Can they provide references from recent projects nearby?
Review References and Reviews
Check multiple sources for feedback:
- Google Reviews: Look for detailed, recent reviews
- Yelp: Read both positive and negative feedback for patterns
- BBB: Check accreditation and complaint resolution
- Direct references: Call 3-5 recent customers and ask about their experience
Get Multiple Estimates
Obtain written estimates from at least three water drilling companies. Each estimate should detail:
- Estimated depth range and drilling cost per foot
- Casing specifications (type, diameter, cost)
- Pump brand, model, and horsepower
- Pressure tank size and type
- Permit costs and who handles permitting
- Timeline from start to completion
- Warranty terms on workmanship and equipment
- Dry hole policy (what happens if water isn't found)
The Water Drilling Process
Understanding what a water drilling company does at each stage helps set expectations:
Phase 1: Site Assessment
Before any drilling begins, the company evaluates your property:
- Identify potential drilling locations meeting setback requirements
- Assess access for the drilling rig (large trucks need adequate clearance)
- Review geology maps and neighboring well records
- Discuss your water needs and budget
- Prepare the estimate based on site conditions
Phase 2: Permitting (1-2 Weeks)
The water drilling company handles permit applications:
- Prepare required site plans and documentation
- Submit application to County Department of Environmental Health
- Pay permit fees ($800-$1,500 in most counties)
- Address any questions from the permitting agency
- Receive approval to proceed with drilling
Phase 3: Drilling (1-3 Days)
The drilling phase is where the well takes shape:
- Drilling rig arrives and sets up on location
- Drilling begins, progressing 50-200 feet per day depending on geology
- Driller monitors for water-producing zones
- Casing is installed as drilling progresses
- Sanitary seal (grout) is pumped to protect groundwater
- Well is developed to clear drilling debris and maximize flow
Phase 4: Inspections (1-3 Days)
County inspections verify proper construction:
- Sanitary seal inspection before grouting
- Final well construction inspection
- Inspector verifies setbacks, casing, and sealing meet code
Phase 5: Pump Installation (1-2 Days)
After passing inspections, the pump system goes in:
- Submersible pump lowered to appropriate depth
- Electrical connections made at wellhead
- Pressure tank and controls installed
- System connected to home plumbing
- Testing and adjustment for proper operation
Phase 6: Completion
Final steps before you have water:
- Water quality samples collected for testing
- Homeowner training on system operation
- Final paperwork and warranty documentation
- Site cleanup
