Why Chlorination is Important for Water Systems
Chlorination is one of the most effective ways to disinfect water systems, helping to eliminate harmful bacteria, viruses, and other pathogens. For both industrial and commercial applications, water quality is a top priority, especially when the water is used for drinking, cooling, or industrial processes.
Regular chlorination helps maintain water hygiene, ensuring the system remains free from microbial contaminants like Legionella.
The Role of Commercial Chlorination
For commercial water systems, proper chlorination ensures water remains safe for use, while also helping to extend the life of pipework by preventing biofilm build-up. It also helps control odours and taste issues caused by organic materials in water. In industrial settings, chlorination not only safeguards health but also protects equipment and processes that rely on clean water.
Types of Water Systems and Chlorination Methods
Small Internal Pipework Systems
For smaller systems, such as those found in offices, schools, or small commercial buildings, chlorination should be carried out periodically, particularly when systems are commissioned, repaired, or experience extended periods of disuse.
Regular testing ensures chlorine levels are maintained within the recommended limits. It’s essential to conduct a thorough flush of the system before reintroducing the water for regular use.
Best Practices for Small Systems
- Conduct chlorination at least annually or after any significant disruption.
- Use a measured amount of chlorine based on the volume of the system.
- Ensure all parts of the system are disinfected, including seldom-used outlets.
Large Industrial Water Systems
In industrial environments, water systems are often more complex and expansive, requiring a more comprehensive approach to chlorination. Systems like cooling towers, large-scale pipework, and storage tanks may need continuous dosing to prevent bacterial growth and biofilm development. For these systems, automated chlorine dosing systems are often employed to maintain consistent chlorine levels.
Best Practices for Large Systems
- Continuous chlorination may be necessary, depending on system complexity.
- Ensure regular monitoring of chlorine levels throughout the system.
- Use shock chlorination during scheduled maintenance or after contamination.
Commercial Chlorination Methods
Chlorination methods vary based on the system and water quality requirements. Here are the most commonly used methods in commercial and industrial applications:
Shock Chlorination
Shock chlorination involves using a high concentration of chlorine to disinfect a water system after contamination, during commissioning, or following major repairs. It’s an effective way to reset the system and remove biofilm or debris that regular chlorination might not eliminate.
Continuous Dosing
For larger systems or those in constant use, continuous dosing is often the best solution. An automatic dosing pump ensures that chlorine levels remain within safe limits, providing ongoing protection. This is particularly useful for cooling towers and industrial processes where water quality is critical.
Dechlorination
Regulations and Compliance for Commercial Chlorination
Chlorination must be carried out in accordance with relevant UK regulations, including the Water Supply (Water Quality) Regulations 2016 and the Health and Safety Executive’s (HSE) guidelines on Legionella control. Ensuring compliance is critical for avoiding fines, penalties, and operational disruptions.
Regular water quality testing and proper documentation are essential. By working with accredited service providers like Pipe Testing Services (PTS), you can ensure full compliance with UK standards, giving you peace of mind and maintaining the safety of your water systems.

Commercial Chlorination - FAQs
What is commercial chlorination?
Commercial chlorination refers to the process of disinfecting water systems in industrial or commercial settings using chlorine. It ensures that water systems remain free from harmful bacteria and comply with UK water quality regulations.
How often should chlorination be carried out?
For most commercial water systems, annual chlorination is recommended. However, more frequent chlorination may be necessary after repairs, commissioning, or periods of disuse.
Is shock chlorination safe for all water systems?
Yes, when performed correctly, shock chlorination is a safe and effective method for disinfecting water systems. It’s ideal for systems that have been contaminated or are being commissioned for the first time.
Can I chlorinate my own water system?
While it’s possible to chlorinate small systems yourself, it’s recommended to work with a professional for larger or more complex systems to ensure safety and compliance with regulations.
What happens if chlorine levels are too high?
Excessive chlorine can cause corrosion in pipes and equipment. It may also produce unpleasant tastes and odours. Regular monitoring and proper dosing prevent these issues.
Do I need to dechlorinate after chlorination?
Dechlorination is often necessary when discharging water into the environment or when high chlorine levels could interfere with industrial processes.
How does chlorination help with Legionella control?
Chlorination is a key method for controlling Legionella bacteria, particularly in large water systems like cooling towers. It eliminates the bacteria and prevents biofilm formation where Legionella can thrive.
