Well Decommissioning in Lake Elsinore, California
Lake Elsinore wraps around the largest natural freshwater lake in Southern California, and the surrounding valley has a long history of private groundwater use. From the historic downtown and Lakeland Village to the hillside neighborhoods of Tuscany Hills and the rural reaches toward the Ortega Mountains, many properties were served by wells long before today's water districts expanded. When a Lake Elsinore property is sold, redeveloped, or connects to municipal water, the unused well must be properly decommissioned under California law and Riverside County ordinance.
Southern California Well Service is a licensed C-57 well contractor based in Ramona with a second office in Anza, serving Riverside County since 2020. We decommission wells throughout the Lake Elsinore area and handle the entire Riverside County permit and reporting process. Below is a clear explanation of the requirements, the procedure, and the cost.
When Decommissioning Is Required
- Selling or refinancing. Lenders and title companies require documented destruction of abandoned wells.
- Connecting to district water. Redundant private wells must be retired properly.
- Replacement wells. A new well requires the old one to be decommissioned.
- Inactive wells. Unused, unmaintained wells are legally abandoned and must be sealed.
- Contamination and safety risk. Wells near the lake's high water table, septic systems, or old agriculture can channel pollutants into the aquifer, and open casings are a hazard.
The Riverside County Permit Process
Lake Elsinore well destruction is permitted by the Riverside County Department of Environmental Health (DEH). A written application and valid permit are required before sealing, and the work must be done by a licensed C-57 contractor. We prepare the application with the destruction method the county requires and pay the fee. Riverside County generally acts on complete applications within about six working days. After approval we complete the work, coordinate inspection, and file the DWR destruction report so the permit is closed.
How the Well Is Destroyed
We follow DWR Bulletin 74-81 and 74-90:
- Verify total depth, casing diameter and material, and water level by sounding.
- Clear obstructions by pulling the pump, drop pipe, wiring, and debris.
- Disinfect the well.
- Seal from the bottom up with neat cement or bentonite grout placed through a tremie pipe, with no voids. The high groundwater common near the lake makes proper bottom-up tremie placement especially important to avoid dilution and bridging.
- Restore the surface by cutting casing below grade, setting a concrete plug, and restoring the ground.
Inspection, Documentation, and Timeline
The county may witness the sealing or inspect the finished work. Most residential Lake Elsinore wells are sealed in one day, and with the county's prompt review the full project usually finishes within one to two weeks. You receive copies of the destruction report.
Costs in Lake Elsinore
Most Lake Elsinore 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 a Licensed C-57 Contractor
California law and Riverside County ordinance require a registered C-57 contractor for well destruction. Near Lake Elsinore's shallow water table, correct grout selection and tremie placement are critical to a lasting seal. We provide the equipment, the county registration, and the documentation that protects you.

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 Lake Elsinore, leaving a well unsealed creates several distinct problems. The shallow water table around the lake makes a proper, void-free seal especially important in Lake Elsinore. 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 Lake Elsinore 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 Lake Elsinore 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.
