- Is Your Contractor Licensed To Work Inside Your Well? Maybe — But Probably Not
An unused well can’t just be capped and forgotten. California law requires it to be permanently and properly sealed, a process the state calls well destruction. Watson Well is a licensed C-57 water well contractor serving Redding, Eureka, Chico, Mt. Shasta, and the surrounding Northern California communities. We handle the entire process from permitting to final inspection, so your property stays safe, compliant, and free of long-term liability.
Well destruction is the permanent decommissioning of a water well: removing any pumping equipment, sealing the borehole from bottom to surface with an approved grouting material, and cutting off the casing so the well can never again serve as a pathway between the surface and groundwater. It’s different from well rehabilitation, which restores a well to service. Destruction is a one-way process meant to close a well for good.
You may hear it called “well abandonment” informally, but California’s Department of Water Resources and most county environmental health departments use the official term “well destruction,” and that’s the standard your project will be measured against.
An old or unused well isn’t just dead weight on a property. Left improperly sealed, it becomes a direct channel for surface water, debris, and contaminants to reach the aquifer below. A poorly abandoned well can:
Properly destroying a well closes off all of these risks permanently and gives you documentation to prove it.
The most common reasons property owners in our service area call us for well destruction include:
If you’re not sure whether your situation calls for destruction, rehabilitation, or another fix, our team can assess the well and walk you through the options before you commit to anything.
Well destruction isn’t a project for a general contractor or a DIY weekend. California law restricts this work to specialty-licensed professionals for good reason.
C-57 licensing is the legal standard. Under the California Contractors State License Board, only a contractor holding an active C-57 Water Well Drilling license is authorized to destroy a well. A general (B) or plumbing license doesn’t qualify, and using an unlicensed contractor can leave the well improperly sealed, void any permit, and leave the property owner exposed if something goes wrong later.
The work has to meet state construction standards. California Well Standards (DWR Bulletins 74-81 and 74-90) set the minimum requirements for how a well must be sealed, including the grouting material, the method for filling the borehole from the bottom up, how the casing is cut and how deep, and how the annular space between the casing and the surrounding formation is sealed. Get any of this wrong and the well can still act as a contamination pathway even though it looks “filled in” from the surface.
A permit and inspection are required. Before work begins, a destruction permit has to be filed with the county environmental health department covering the well’s location, depth, and construction details. Once the job is done, the county typically has to inspect and sign off, and a completion report gets filed with the state. A licensed contractor knows exactly what each county in our service area requires and handles that paperwork as part of the job, not as an afterthought.
Improper destruction is a liability that outlives the project. As the property owner, you carry responsibility for what a well on your land does to the groundwater beneath it, even a well you didn’t drill yourself. Hiring a licensed contractor and getting a documented, permitted destruction is what actually closes that liability out.
Watson Well holds an active C-57 license (CSLB #947596) and is a member of the California Groundwater Association and the National Groundwater Association. Every well we destroy is sealed to DWR standard, permitted through the appropriate county, and documented so you have proof the job was done right.
We inspect the well, confirm its depth, diameter, and construction, and review any existing records so we know exactly what we're working with.
We file the destruction permit with your county's environmental health department and handle the paperwork on your behalf.
Pumps, piping, wiring, and any other equipment are pulled from the well.
Neat cement grout (or another county-approved sealing material) is placed from the bottom of the well to the surface using a tremie pipe, displacing water and fully sealing the borehole as it fills.
The casing is cut and removed to the required depth below grade so it can't become a future conduit or surface hazard.
The site is filled to grade and finished so there's no depression, standing water, or exposed casing left behind.
We coordinate the county inspection and provide you with the completed destruction report for your records. That's the paperwork you'll want on hand for a future sale, refinance, or county inquiry.
Watson Well provides licensed well destruction throughout our Northern California service area, including Redding, Eureka, Chico, Mt. Shasta, and the surrounding communities. If you’re not sure whether your property falls in our service area, give us a call. We’re happy to check.
Yes. Well destruction requires a permit from your county environmental health department before work begins, and typically a final inspection once the work is complete. We handle the permitting process as part of every job.
No. Only a licensed C-57 water well contractor can legally perform well destruction in California. Filling a well with dirt, debris, or unapproved materials doesn’t meet state sealing standards and can leave you out of compliance and still liable for the well.
It depends on the well’s condition, age, and construction, and what you need from your water system going forward. We assess each well individually, and if rehabilitation is a realistic option, we’ll tell you.
It stays a legal and environmental liability tied to the property. Issues frequently surface during a real estate transaction, a county inspection, or a groundwater contamination investigation, often at the least convenient time to deal with it.
An unused, undocumented well can slow down or complicate escrow. Having a well properly destroyed and documented ahead of a sale removes that question for buyers, title companies, and lenders.
Timelines depend on the well’s depth and construction and on county permit turnaround. We’ll give you a realistic timeline for your specific well once we’ve assessed it.
If you have a well on your property that’s no longer in use, don’t leave it as an open question. Contact Watson Well for a site assessment, and we’ll walk you through the permitting, process, and cost for your specific well.
