When a well is no longer needed, California law requires proper destruction—not just covering it up. Improperly abandoned wells become contamination pathways that can affect entire aquifers.

When to Abandon a Well

  • Connecting to public water and no longer need well
  • Well is dry or produces inadequate water
  • Well is contaminated and treatment isn't practical
  • Replacing with a new well
  • Property development requires removal
  • County requires destruction of unpermitted well
  • Permit required: Obtain destruction permit from county environmental health
  • Licensed contractor: Only C-57 licensed well drillers can legally destroy wells
  • State standards: Must follow California Well Standards (Bulletin 74-90)
  • Completion report: Driller files report with state DWR

The Destruction Process

  1. Obtain permit: Application with well location and construction details
  2. Remove equipment: Pull pump, pipe, wiring from well
  3. Fill from bottom up: Pump neat cement grout from bottom, displacing water
  4. Seal annular space: Grout between casing and surrounding soil
  5. Cut casing: Remove casing to at least 5 feet below grade
  6. Fill to surface: Complete filling and cap
  7. County inspection: Verify proper destruction
  8. File completion report: Document destruction with state

Why Proper Abandonment Matters

Risks of Improper Abandonment

  • Groundwater contamination: Surface contaminants can reach aquifers
  • Physical hazards: Open or poorly covered wells are dangerous
  • Legal liability: Property owner responsible for contamination
  • Property sale issues: Title search may reveal problems
  • Neighbor impact: Your abandoned well can contaminate their water

Abandoning a Well

California has some of the most comprehensive well regulations in the country—and for good reason. Proper well construction and management protects both your water supply and the shared groundwater resources that thousands of properties depend on.

California Well Regulations Overview

Well construction, modification, and destruction in California are governed by several layers of regulation:

Permitting Requirements

In San Diego County, the Department of Environmental Health (DEH) handles well permits. You need a permit for:

Permit applications require a site plan showing the well location relative to property lines, septic systems, and other potential contamination sources.

Setback Requirements

Minimum distances between a well and potential contamination sources (San Diego County):

These setbacks can make well placement challenging on smaller lots. We help navigate these requirements during our site evaluation.

Contractor Licensing

California law requires a C-57 Water Well Drilling license for anyone who drills, modifies, or destroys a water well. This is a specialized classification—a general contractor's license is NOT sufficient.

Always verify your contractor's license at www.cslb.ca.gov. SCWS holds CSLB License #1086994 with active C-57 classification.

Well Owner Responsibilities

As a well owner in California, you're responsible for:

Well Destruction Requirements

Typical cost for proper well destruction in San Diego County: $1,500–$5,000 depending on well depth and condition.
