What is a well video inspection?
A water well video inspection is a process of viewing wells using state-of-the-art water proof camera systems. This allows the inspector to view areas that physically can’t be viewed by human eyes, and analyze and diagnose issues within a water well system..
How does a well video inspection work?
Well inspections involve lowering a cable-suspended camera down the well to record downward and side views of the casing at indicated depths. The camera includes LED lights that illuminates the area, helping to create a clear image and video of the surrounding area. The video is transferred to a DVD or USB drive, and relevant findings are documented in a summary report. All information is copied for clients to keep for their records.
What are the benefits of a video well inspection?
There are numerous benefits to using a video recording device to inspect a water well including but not limited to the following:
- Encrustation such as rust, algae, or solids deposits
- Corrosion in areas of perforations or at welded seams
- Deformation from collapse or compression
- Breaches, such as holes
- Inspection prior to purchase for documentation and estimating any repairs or replacement
- Documenting post cleaning process success
- Inspection and Document obstruction such as: debris, residual pump parts, foreign objects
- Review wells that lack construction records
- Determining the possibility of a dry well
- Dropped pump removal
- Dropped pipe removal
How is a well video inspection data used?
Our well rehab and repair specialists use the inspection findings to outline next step suggestions. Our best practices approach has been fine-tuned during our 50 years of business, using our knowledge and expertise to offer the best analysis and solutions in all of Southern Arizona. These recommendations are then discussed with clients and may include – but are not limited to – the following services we professionally provide
Brush & bail
Brushing is done with steel or plastic bristles attached to a drilling rig. The walls of the well casing are scrubbed clean of mineral deposits and corrosive byproducts.
The sediment that’s brushed loose may settle to the bottom of the well. And, sometimes, other particulate matter has already accumulated in that area. The bailing procedure is done after brushing, using a special tool to capture and scoop out the settled material.
reverse circulation clean out
High-pressure jetting is one technique used to eliminate deposits. An adjustable, multi-head tool is lowered into the well, aiming jets of water at the debris.
acid washing
Well rehabilitation may require the use of chemicals. Chemicals are carefully chosen and blended to remove encrusted materials as effectively and safely as possible.
Mineral acids can be used to dissolve concentrations of carbonates, silicates, magnesium hydroxide, iron oxide and other mineral precipitates. Organic acids can work as a solvent for some sulfate and phosphate compounds, and they can be effective against microorganisms. For oil contamination or heavy biological clogging, rehabilitation may require the use of caustic or alkaline products.
The necessary chemicals are placed in the well and agitated frequently for one to three days. Finally, fresh water is pumped through to clean and flush the system.
liner installation
Well liners are used to repair damaged well casings that leak or are giving out. Liners protect against sediments and contaminants entering the water supply. Liners are easy to maintain and can be customized to fit specific needs.
