What is Pipe Sterilization and Sanitisation?
Pipe sterilization is a thorough, intensive process that aims to eliminate all microorganisms from water pipes. This procedure is typically employed in several key scenarios:
- Installation of new pipework
- After major repairs or replacements
- Following contamination incidents or outbreaks
Sanitisation, on the other hand, is a regular maintenance procedure that reduces microorganisms to safe levels. It’s an ongoing process crucial for the day-to-day safety of our water supply.
The Sterilization Process: A Step-by-Step Guide
Flushing
We begin by flushing pipes with clean water to remove debris, sediment, and loose contaminants. This step is crucial for ensuring the effectiveness of the subsequent chemical treatment.
Chemical Treatment
Next, we introduce a strong disinfectant, usually chlorine-based. In the UK, sodium hypochlorite is commonly used due to its effectiveness and compliance with water regulations.
You can learn more about our chlorination services and chlorination in general, on our alternative pages via our website. Get in contact if you require pipework chlorination.
Contact Time
The disinfectant remains in the pipes for about 24 hours. This duration ensures that even stubborn biofilms and hard-to-reach areas are thoroughly treated.
Final Flush and Test
After the contact period, we flush the system again with clean water and conduct rigorous testing to ensure the absence of harmful microorganisms and chemical residues.
Sanitisation: The Key to Ongoing Pipe Cleanliness
Regular sanitisation is vital for maintaining water quality. It involves:
- Periodic flushing to remove sediment and biofilm build-up
- Maintaining proper chlorine levels to prevent microbial growth
- Ongoing water quality monitoring to ensure compliance with UK drinking water standards
Why These Processes Matter: Protecting Public Health
Clean pipes are the foundation of safe water delivery. These processes protect against a range of threats:
- Harmful bacteria like E. coli and Legionella
- Viruses that can survive in water systems
- Protozoa such as Cryptosporidium
- Biofilm formation, which can harbour pathogens
Moreover, they’re essential for compliance with UK water standards, ensuring that every tap in the country delivers safe, clean water.
UK Regulations and Standards: A Stringent Framework
In the UK, we adhere to some of the strictest water quality guidelines in the world:
- DWI Compliance: All procedures must meet Drinking Water Inspectorate standards, which oversee water quality and sufficiency in England and Wales.
- BS 8558:2015: This British Standard provides comprehensive recommendations for the design, installation, testing, and maintenance of services supplying water for domestic use within buildings and their curtilages.
- Water UK Standards: The water industry has developed a set of standards for the sterilization of water mains, widely adopted across the UK to ensure consistency and safety.
- WRAS Approval: All products used in water systems, including disinfectants, must be approved by the Water Regulations Advisory Scheme to ensure they do not contaminate the water supply.
- The Water Supply (Water Quality) Regulations 2016: These regulations set the legal framework for drinking water quality in England and Wales, with similar regulations in Scotland and Northern Ireland.

FAQs - Pipe Sterilization & Sanitisation
How often should pipes be sanitised?
The frequency depends on your system’s specifics, but generally, annual sanitisation is recommended for most systems. However, high-risk environments like hospitals may require more frequent treatments. We can assess your needs and create a tailored plan.
Is pipe sterilization necessary for new buildings?
Absolutely. New pipes can harbour contaminants from manufacturing and installation processes. Sterilization ensures that your new water system starts off clean and safe.
How long does pipe sterilization take?
The process typically takes 24-48 hours, depending on the system size and complexity. This includes the preparation, chemical contact time, and post-sterilization testing.
Can I use my water during the sterilization process?
No, you’ll need to avoid using water during this time to ensure the effectiveness of the treatment and for safety reasons. We’ll provide clear instructions to minimise disruption to your daily activities.
What's the difference between sterilization and sanitisation?
Sterilization aims to eliminate all microorganisms, while sanitisation reduces them to safe levels. Sterilization is more intensive and used less frequently, typically for new installations or after major works.
Are the chemicals used in pipe sterilization safe?
Yes, we use chemicals approved by the Drinking Water Inspectorate that are safe when properly applied and flushed. Our process ensures no harmful residues remain in your water system.
How do I know if my pipes need sterilization?
Signs that your pipes might need sterilization include discoloured water, odd tastes or smells, or recent contamination incidents. If you’re unsure, it’s best to contact us for a professional assessment.
