What Is Well Chlorination?
Well chlorination, also called shock chlorination, is a process of introducing a strong chlorine solution into your water well system to kill bacteria, viruses, and other microorganisms. It’s used to disinfect:
Newly drilled wells
Existing wells after repairs or flooding
Wells with confirmed contamination
Wells with persistent odor or taste issues
This process treats the well casing, piping system, and pressure tank to eliminate coliform bacteria and ensure the water supply is safe.
Why You Need to Chlorinate Your Well
Over time, private water wells can become contaminated with bacteria and organic matter. This can happen due to heavy rainfall, flooding, cracks in the casing, or simply from lack of regular maintenance. Contaminated water can pose serious health risks and lead to poor water taste, discoloration, and foul odors.
Chlorination is the recommended disinfection method by the EPA and public health departments. It’s an effective way to sanitize your well and restore water quality. If you’ve recently had a new pump installed, repaired the well, or noticed any signs of contamination, it’s time to consider shock chlorination — and 77 Water Well Inc. is here to help.
The 77 Water Well Inc. Chlorination Process
Our well water chlorination process is thorough, safe, and compliant with Texas Department of Licensing and Regulation (TDLR) and EPA guidelines. Here’s how it works:
1. Inspection and Water Testing
Before we start chlorination, we inspect the well system for potential causes of contamination and may recommend bacteria testing. This ensures that we understand the problem and apply the correct treatment dosage.
2. Mixing the Chlorine Solution
We calculate the appropriate chlorine dosage based on your well’s depth and diameter. Too much chlorine can damage equipment, and too little will be ineffective. We only use approved chlorine compounds for disinfection.
3. Circulation and Retention
The chlorine is circulated throughout your entire water system, including the pressure tank and piping. Then the solution sits — or “retains” — in the system for 12 to 24 hours. This is key to ensuring bacteria are fully eliminated.
4. Flushing the System
After the retention period, the system is flushed until all chlorine residual is gone. We ensure that no traces remain in your home plumbing and that the water is safe for consumption.
5. Post-Chlorination Testing
Once chlorination is complete, we recommend follow-up water testing to confirm the removal of bacteria and ensure that the water is suitable for drinking.
When Should You Chlorinate Your Well?
Routine well chlorination should be part of your home water safety plan, especially if you rely on a private well for your household supply. Here are some scenarios where you should contact 77 Water Well Inc. for service:
After new well construction
After pump installation or service
After flooding or heavy storms
After noticing sulfur odors or taste issues
If water tests show E. coli or coliform bacteria
Every 6 to 12 months as preventative maintenance
