Well Decommissioning in Wildomar, California
Wildomar, one of Riverside County's newer incorporated cities, still carries the semi-rural character of the Elsinore Valley. Between the Bundy Canyon area, the slopes toward the Cleveland National Forest, and the older homesteads along Palomar Street, many properties were developed with private wells before sewer and water districts reached them. As Wildomar continues to grow and parcels change hands, those old wells must be properly decommissioned under California law and Riverside County ordinance rather than left abandoned.
Southern California Well Service is a licensed C-57 well contractor with offices in Ramona and Anza serving Riverside County since 2020. We decommission wells throughout Wildomar and handle the full Riverside County permit and documentation process. Here is what to expect.
When Is Decommissioning Required?
- Selling your property. Title and lending requirements often call for proof that abandoned wells are sealed under permit.
- New construction. Building over or near an old wellhead requires it to be destroyed first.
- Connecting to district water. A now-redundant private well must be retired properly.
- Replacement wells. A new well requires the original to be decommissioned.
- Inactive wells and contamination risk. Unused wells are legally abandoned, and casings near septic systems can carry pollutants into the aquifer.
The Riverside County Permit Process
Wildomar well destruction is regulated by the Riverside County Department of Environmental Health (DEH). A written application and valid permit are required before any sealing, and only a licensed C-57 contractor may perform the work. We prepare the application with the required destruction method, pay the fee, and submit it. Riverside County typically acts on complete applications within about six working days. After approval we do the work, coordinate the inspection, and file the DWR destruction report to close the permit.
How the Well Is Sealed
We follow DWR Bulletin 74-81 and 74-90:
- Verify depth, casing diameter and material, and water level.
- Clear the pump, drop pipe, wiring, and obstructions.
- Disinfect with chlorine.
- Seal from the bottom up using a tremie pipe and neat cement or bentonite grout, eliminating voids; pressure-grout perforated intervals.
- Restore the surface by cutting casing below grade, setting a concrete plug, and restoring the ground.
Inspection, Documentation, and Timeline
The county may witness or inspect the completed work. A typical Wildomar residential well is sealed in one day, and with the county's prompt review most projects finish within one to two weeks. You receive the destruction report for your records.
Costs in Wildomar
Most Wildomar projects run $1,500 to $5,000+, depending on depth, casing, and access. County permit fees add $200 to $800, and our $125 diagnostic fee is credited toward the work.
Why Use a Licensed C-57 Contractor
California law and Riverside County ordinance require well destruction by a registered, licensed C-57 contractor. Proper full-length sealing protects the Elsinore Valley groundwater and ensures your destruction is documented and accepted by the county. We bring the equipment, the registration, and the paperwork.
Serving Wildomar and the Elsinore Valley
We serve Wildomar including the Bundy Canyon and Palomar areas, plus neighboring Lake Elsinore, Murrieta, Menifee, and Canyon Lake. Call us for a straightforward assessment.
What Sets Wildomar Apart
Wildomar incorporated only in 2008, but its parcels are much older, and that gap matters for well owners. Many lots were developed as county land decades before the city existed, often with private wells and septic systems that were never formally documented when district services finally arrived. As a result, sellers and their agents are frequently surprised to learn during escrow that a long-forgotten well is still recorded on the property. Addressing it proactively, rather than during a 30-day closing window, keeps your sale on schedule. We routinely locate, assess, and decommission these legacy wells across the Bundy Canyon, Palomar Street, and Sedco Hills areas, and we provide the recorded destruction documentation that title companies and lenders ask for. Because the Elsinore Valley shares a connected groundwater system, sealing each abandoned well properly also protects the supply that active wells in Wildomar, Lake Elsinore, and Sedco still rely on.

What Happens If You Don't Decommission an Old Well
An abandoned well is not a passive hole in the ground. It is an open vertical pathway that connects the surface directly to the aquifer, bypassing the natural soil layers that normally filter contaminants. In Wildomar, leaving a well unsealed creates several distinct problems. In the semi-rural Elsinore Valley, older Wildomar homesteads frequently sit close to septic leach fields. Surface runoff, fertilizer, fuel, and bacteria can travel straight down a corroded or open casing and degrade the groundwater that neighboring wells still draw from. Old wells also collapse over time, and a hidden, partially filled shaft is a genuine physical hazard to children, pets, livestock, and equipment. From a financial standpoint, an undocumented well is a recorded liability that can surface during a title search and stop a sale cold. Decommissioning resolves all of these at once: it removes the contamination pathway, eliminates the safety hazard, and produces a recorded document proving the well was properly retired.
A Closer Look at the Sealing Materials
The heart of a proper decommissioning is the sealant, and Riverside County follows the California Department of Water Resources standards for what may be used. The acceptable materials are neat cement grout (cement and water, sometimes with a small bentonite addition), sand-cement grout, and bentonite grout. Each has a place: neat cement is the workhorse for sealing the casing itself, while bentonite is often used where a flexible, low-permeability seal is preferred. The material must be placed by tremie pipe from the bottom of the well upward so that the grout displaces water and fills every foot of the bore without trapping voids or bridging partway down. Simply dumping dry sacks or concrete from the top is not compliant and is the most common reason a do-it-yourself "abandonment" fails inspection. Where a well is gravel-packed or has perforated sections, the grout is placed under pressure so it penetrates the annular space and the surrounding formation, not just the inside of the casing.
The Riverside County Department of Environmental Health Permit, Step by Step
One advantage of working in Riverside County is the predictable permit timeline. The Riverside County Department of Environmental Health (DEH) is required to approve or deny a complete and accurate well permit application within about six working days, or the application is deemed approved. We prepare applications carefully the first time so they are not kicked back for missing information, which is the most common cause of delay. The same permit framework that governs new wells also governs destruction: no one may dig, drill, reconstruct, or destroy a water well in Wildomar without first filing a written application and holding a valid permit.
Once the permit is in hand, the field sequence is straightforward but exacting. We mobilize our rig to the wellhead, sound the well one more time to confirm conditions match the permit, pull the pump and any down-hole equipment, disinfect, and then grout from the bottom up. A county inspector may be present to witness the seal or may inspect the completed surface. When the work is done, we complete the Department of Water Resources Well Completion Report documenting the destruction, including the materials used and the volumes placed, and we file it with the county and the state. You receive copies for your permanent records, your insurance, and any future buyer's due diligence.
How to Prepare Your Wildomar Property
You can make the project faster and cheaper with a little preparation. Clear vegetation and stored items away from the wellhead so our equipment has a path. Locate any paperwork you have on the well, such as the original driller's report, the well's depth, or its construction details, which helps us size the job accurately. If the well is inside a pump house or under a structure, let us know during the diagnostic visit so we can plan access. If you are selling, start early; the permit and inspection cycle takes time, and rushing it during escrow adds stress. We are happy to coordinate directly with your real estate agent, escrow officer, or environmental consultant.
