How Long Does It Take to Drill a Well?

Timeline Overview

Quick Summary

The Two Timelines

People often ask "how long" meaning two different things:

• Drilling only: 1-5 days (the rig on site)
• Start to water: 2-6 weeks (typical)

Drilling Time

By Depth

By Formation

• Soft formations: Sand, clay, decomposed granite—fast drilling
• Medium: Weathered rock, soft bedrock—moderate speed
• Hard rock: Granite, basalt—slower, more bit wear

San Diego County

• Depths typically 300-600 feet
• Often decomposed granite or fractured rock
• Most wells drill in 1-3 days

The Complete Process

1. Site Assessment (1-7 days)

• Site visit by driller
• Review geology, access, utilities
• Discuss expectations
• Provide estimate

2. Permits (1-4 weeks)

• San Diego County: typically 2-4 weeks
• Requires application, fees, site plan
• Environmental health review
• Some areas have additional requirements

3. Scheduling (1-4 weeks)

• Depends on driller's workload
• Busier in spring/summer
• May be faster in fall/winter

4. Drilling (1-5 days)

• Rig arrives, sets up
• Drilling begins
• Continue until target depth or good water
• Log formation, water zones

5. Casing & Grouting (1-2 days)

• Install steel or PVC casing
• Grout annular space (seal)
• Protects groundwater
• May need cure time

6. Well Development (4-24 hours)

• Remove drilling fluids
• Clear sand and debris
• Surge and bail well
• Yield test

7. Pump Installation (1 day)

• Select pump for depth and yield
• Install pump, pipe, wire
• Connect electrical
• Install pressure tank
• Test system

8. Final Inspection

• County inspection if required
• Water quality test
• Turn over to homeowner

What Affects Timeline

Speeds Things Up

• Simple permit situation
• Good site access
• Favorable geology
• Off-season (less demand)
• Experienced driller

Slows Things Down

• Complex permits (environmental review)
• Difficult access (steep terrain)
• Hard rock formations
• Very deep well needed
• Weather delays
• Equipment breakdowns
• Peak season backlog

Unexpected Delays

• Hitting unexpected rock
• Lost circulation (drilling fluid loss)
• Stuck drill string
• Poor water at first depth
• Need to drill deeper

Planning Tips

Start Early

• Don't wait until you're desperate for water
• Allow 2-3 months for the full process
• Consider seasonal demand

Get Permit Started

• Permits often take longest
• Can apply while getting quotes
• Ask driller to help with application

Questions to Ask

• Current scheduling lead time?
• Expected drilling time for your area?
• Do you handle permits?
• What could cause delays?

New Construction

• Drill early—water needed for construction
• Plan well location around future structures
• Access easier before buildings exist

Well Service in How Long Does It Take

How Long Does It Take properties in San Diego County rely on private wells drilled through the Peninsular Ranges batholith, primarily granitic and metamorphic rock. Local geological conditions affect everything from drilling depth and cost to water quality and pump selection.

Drilling Conditions in How Long Does It Take

Well drilling in How Long Does It Take typically encounters the Peninsular Ranges batholith, primarily granitic and metamorphic rock. Most wells can be completed in 1-3 days under normal conditions. The relatively moderate depths keep drilling costs reasonable, though rocky formations can slow progress.

San Diego County requires a well permit from the Department of Environmental Health (DEH) before drilling can begin. The permit process typically takes 2-4 weeks and costs $800-$1,500 depending on the parcel. We handle the entire permit process for How Long Does It Take properties.

Frequently Asked Questions

How long does it take to drill a well?

Drilling itself: 1-5 days depending on depth and geology. Complete process (permits to water): 2-6 weeks typically.

Can a well be drilled in one day?

Drilling yes, often. But casing, development, and pump installation add time. Plan 1-2 weeks minimum from drilling to usable water.

What's the longest part of the process?

Usually permits and scheduling. Drilling itself is relatively quick. Allow 1-4 weeks for permits in San Diego County.

Can I get a well faster?

Off-season scheduling helps. Having permits ready helps. But geology and depth determine drilling time—no shortcuts there.

How long until I have water?

From drilling start: typically 1-2 weeks. From initial contact: 2-6 weeks. Varies by permit time and driller availability.
