Why Water Tank Chlorination is Important
Water tank chlorination is a vital safeguard for UK businesses, organisations, and homes that use water storage tanks. Here are the key reasons why this process matters:
- Eliminates Harmful Microorganisms: Chlorination effectively kills bacteria, viruses, and other pathogens, ensuring water safety.
- Prevents Biofilm Formation: Chlorine prevents the build-up of biofilm, a slimy layer where harmful microorganisms thrive.
- Regulatory Compliance: Adhering to chlorination guidelines ensures compliance with UK health and safety regulations, preventing legal and financial penalties.
- Protects Public Health: Clean, chlorinated water helps prevent outbreaks of diseases such as Legionnaires' disease.
Without regular chlorination, water systems can become breeding grounds for bacteria, leading to health risks and regulatory issues.
UK Regulations for Water Tank Chlorination
In the UK, water tank chlorination is regulated by several key standards. Compliance with these regulations is essential to avoid penalties and maintain water quality:
- The Water Supply (Water Quality) Regulations 2016: Governs the safety of drinking water in the UK.
- Health and Safety Executive’s Approved Code of Practice (ACoP) L8: Provides guidelines on controlling Legionella in water systems.
- British Standard BS 8558:2015: Covers the design, installation, and maintenance of water systems, including chlorination.
Regular cleaning and disinfection of water tanks are mandatory under these regulations. Failing to comply can result in contamination, public health risks, and legal consequences.
The Water Tank Chlorination Process
At Pipe Testing Services (PTS), we follow a meticulous chlorination process to ensure thorough disinfection and regulatory compliance. Here’s an overview of the steps involved:
- Draining and Cleaning the Tank: The water tank is emptied, and any sludge or debris is removed.
- Applying Chlorine Solution: A chlorine solution (usually sodium hypochlorite) is introduced to disinfect the tank.
- Contact Time: The chlorine is left to act for a specified period, ensuring it kills all microorganisms.
- Flushing the System: After disinfection, the system is thoroughly flushed to remove any residual chlorine.
- Testing Water Quality: Water samples are tested for chlorine residuals and microbial contaminants to confirm safety.
These steps ensure that the tank is not only clean but also free from harmful pathogens. PTS technicians use advanced technology to deliver fast, accurate results, giving you peace of mind.

It is also valuable for keeping accurate records, making it easier to demonstrate adherence to safety standards during audits or inspections.
Maintaining Water Quality Post-Chlorination
While chlorination is effective in eliminating bacteria, maintaining water quality requires ongoing attention. To keep your system in optimal condition, PTS recommends:
- Regular Water Testing: Frequent testing ensures that your water continues to meet safety standards.
- System Maintenance: Proper maintenance, including tank cleaning and pipe inspections, prevents bacterial growth.
- Temperature Control: Keeping water temperatures below 20°C or above 60°C helps inhibit the growth of Legionella.
- Tank Insulation and Covering: Proper insulation and covering protect your water tank from external contamination.
By following these best practices, you can ensure that your water remains safe and compliant long after chlorination.
