What is Pipework Chlorination?
Pipework chlorination involves treating water pipes with a chlorine solution to kill bacteria and ensure safe water quality. We perform chlorination services nationwide, ensuring thorough disinfection of pipework and internal water systems to provide clean, potable water.

When is Pipework Chlorination Required?
Chlorination of pipework is essential in various scenarios, including:
- New Water System Installations: Ensures initial cleanliness and safety.
- After Major Repairs or Modifications: Prevents contamination from construction activities.
- Suspected or Detected Contamination: Necessary if water quality tests reveal harmful bacteria.
- Following Periods of Disuse or Stagnation: Restores water safety in dormant systems.
- Regular Maintenance for Large-Scale Systems: Essential for ongoing water quality assurance in extensive networks.
The Pipework Chlorination Process
Here’s a simplified overview of our chlorination process:
Evaluate the system’s condition and determine the appropriate chlorination method.
Isolate the section to be chlorinated and secure all fittings.
Thoroughly flush the system with clean water to remove debris and sediment.
Mix a chlorine solution to the required concentration (typically 50mg/l or higher).
Mix a chlorine solution to the required concentration (typically 50mg/l or higher).
Fill the system with the chlorine solution, ensuring all parts are in contact with the disinfectant.
Allow the solution to remain in the system for a specified period, usually at least one hour.
Flush the system with clean water and neutralise any remaining chlorine.
Conduct water quality tests to ensure the chlorination process was successful.
Obtain necessary certifications to confirm the system meets required standards.
Differences in Chlorinating New vs. Existing Pipework
New Pipework Chlorination
When chlorinating new pipework, the focus is on removing manufacturing residues and preventing initial contamination:
- Initial Flushing: Remove any debris from installation.
- Higher Chlorine Concentrations: Up to 100mg/l to ensure complete disinfection.
- Shorter Contact Time: Typically 1-2 hours due to lack of established biofilms.
- Attention to New Fittings and Joints: Ensure all parts are properly disinfected.
Existing Pipework Chlorination
Chlorinating older pipework presents unique challenges:
- Rigorous Initial Assessment: Identify potential problem areas.
- Descaling or Mechanical Cleaning: May be required before chlorination.
- Longer Contact Times: Up to 24 hours to penetrate established biofilms.
- Multiple Chlorination Cycles: Necessary for heavily contaminated systems.
- Leak and Weakness Testing: Ensure the integrity of older pipes.
