What is Pipework Chlorination?
Pipework chlorination is a specialised procedure where water pipes and associated systems are cleaned and disinfected using a chlorine-based solution. This process is designed to eradicate harmful bacteria, viruses, and other microorganisms. Ultimately, it’s a safety measure where chlorine is used to clean water pipes and protect public health.
When is Chlorinating Pipework Required?
Pipework chlorination is necessary in various scenarios, including:
- Installation of new water systems or pipework
- After major repairs or modifications to existing systems
- When contamination is suspected or detected
- Following periods of disuse or stagnation
As part of regular maintenance schedules for large-scale water systems and water mains.
The Pipework Chlorination Process – How to Chlorinate Pipework
Here’s the simplified process that we carry out for clients across the UK:
- Initial Assessment: Evaluate the system's condition and determine the appropriate chlorination method.
- System Preparation: Isolate the section to be chlorinated and ensure all fittings are secure.
- Flushing: Thoroughly flush the system with clean water to remove debris and sediment.
- Chlorine Solution Preparation: Mix a chlorine solution to the required concentration (typically 50mg/l or higher).
- Chlorination: Fill the system with the chlorine solution, ensuring all parts are in contact with the disinfectant.
- Contact Time: Allow the solution to remain in the system for a specified period, usually at least one hour.
- Flushing and Neutralization: Flush the system with clean water and neutralize any remaining chlorine.
- Testing: Conduct water quality tests to ensure the chlorination process was successful.
- Certification: Obtain necessary certifications to confirm the system meets required standards.
Differences in Chlorinating New vs. Old Pipework
New Pipework Chlorination
When chlorinating new pipework, or water mains chlorination, the focus is on removing manufacturing residues and preventing initial contamination:
- Thorough initial flushing to remove any debris from installation.
- May require higher chlorine concentrations (up to 100mg/l) to ensure complete disinfection.
- Shorter contact time often sufficient (1-2 hours) due to lack of established biofilms.
- Special attention to newly connected fittings and joints.
- Chlorination: Fill the system with the chlorine solution, ensuring all parts are in contact with the disinfectant.
New Pipework Chlorination
Chlorinating older, existing pipework presents unique challenges:
- More rigorous initial assessment to identify potential problem areas.
- May require descaling or mechanical cleaning before chlorination.
- Longer contact times (up to 24 hours) to penetrate established biofilms.
- Multiple chlorination cycles may be necessary for heavily contaminated systems.
- Additional testing for leaks or weaknesses in older pipes.
Do I need Pipework Chlorination?
Chlorinating pipework can be crucial in many situations.
Whether for new installations, system maintenance, or addressing contamination concerns, professional pipework chlorination is an essential service for businesses, municipalities, and property managers alike. You may need pipes chlorinated if;
