We understand the critical role that chlorination plays in ensuring water safety across a wide range of systems. From public swimming pools to large-scale industrial cooling towers, each application presents its own unique challenges. To address these challenges, we offer tailored chlorination services designed to meet the specific needs of each system while ensuring full compliance with UK regulations.
In this guide, we explore the importance of chlorination for various specialised applications, outlining the specific requirements for each and highlighting how we deliver effective and environmentally responsible solutions for water treatment across the UK.

Why Chlorination is Important in the UK
Chlorination is one of the most effective methods for disinfecting water systems, ensuring that water remains safe and free from harmful pathogens such as Escherichia coli and Legionella. In the UK, chlorination is essential for maintaining public health, as well as meeting strict regulatory requirements for water safety.
The Water Supply (Water Quality) Regulations 2016 mandate chlorination for certain types of installations and maintenance activities, ensuring that water systems are properly disinfected before being put back into service. Regular chlorination also helps to prevent contamination, ensuring that newly installed or repaired water systems are free from harmful microorganisms and biofilm before being used.
Key Benefits of Chlorination:
Chlorination effectively kills harmful bacteria, viruses, and other microorganisms, preventing the spread of waterborne diseases.
Chlorination is required by UK law for certain water systems, ensuring compliance with the Water Supply (Water Quality) Regulations 2016 and other relevant guidelines.
Regular chlorination ensures that water systems remain free from biofilm and other contaminants that can compromise water quality and system performance.
Specialised Applications for Chlorination
Chlorination requirements can vary significantly depending on the application, with each type of water system requiring specific treatment approaches to ensure safety and effectiveness.
In the UK, swimming pools are subject to strict regulations to maintain water safety and clarity. Chlorination is essential for controlling bacteria, viruses, and other pathogens, as well as for preventing the buildup of organic material that can lead to the formation of chloramines.
Key Considerations for Pool Chlorination:
Maintaining Proper Chlorine Levels: Indoor swimming pools should have free chlorine levels between 1.0 and 3.0 mg/l, while outdoor pools may require closer monitoring due to exposure to environmental contaminants.
Balancing pH Levels: Chlorine works most effectively when the pool’s pH level is kept between 7.2 and 7.4. We ensure that both chlorine and pH levels are regularly tested and adjusted for optimal disinfection.
Chloramine Prevention: High bather loads and insufficient maintenance can lead to the formation of chloramines, which cause eye and skin irritation. We help prevent this through regular water testing and periodic shock chlorination.
Weather Factors for Outdoor Pools: Outdoor pools are more susceptible to contamination from environmental factors such as rain and wind, which can dilute chlorine levels and introduce debris. We provide customised maintenance plans to address these challenges.
How We Can Help:
Routine chlorination services
Shock treatments to reset chlorine levels
Comprehensive pool water quality management to ensure compliance and bather safety
Cooling towers face unique water safety challenges, particularly with the potential growth of Legionella bacteria, which can cause Legionnaires’ disease. The Health and Safety Executive (HSE) Approved Code of Practice (ACoP L8) and the Control of Substances Hazardous to Health (COSHH) Regulations 2002 provide strict guidelines for managing Legionella risks in cooling towers, including chlorination requirements.
Key Services for Cooling Tower Chlorination:
Chlorine Dosing: Cooling towers typically require a minimum free chlorine residual of 0.5 mg/l to control microbial growth. We provide precise dosing systems to ensure chlorine levels remain within the required range.
Shock Treatments: Periodic shock chlorination is used to break down biofilms and remove scale, which can protect bacteria from regular chlorine dosing.
Regular Monitoring: We offer ongoing testing and monitoring services to ensure cooling towers remain compliant with HSE guidelines and free from Legionella bacteria.
How We Can Help:
Continuous chlorine dosing solutions
Regular chlorine testing and Legionella risk management
Compliance with ACoP L8 and COSHH regulations
Internal pipework and water tanks, especially in commercial, industrial, or healthcare facilities, require thorough chlorination to ensure the system is safe for use after installation, repair, or periods of dormancy.
Challenges of Pipework Chlorination:
Uniform Distribution of Chlorine: Dormant pipes and tanks can develop biofilms or scale, which may prevent chlorine from reaching all areas. We use advanced methods to ensure even chlorine distribution throughout the system.
Flushing Systems: Flushing is required both before and after chlorination to remove any debris and ensure that residual chlorine levels are within safe drinking water standards.
Preventing Corrosion: High concentrations of chlorine can corrode certain materials. We carefully balance chlorine dosing to achieve effective disinfection while minimising the risk of corrosion.
How We Can Help:
Complete chlorination and flushing services for new or dormant systems
Compliance testing and certification
System monitoring to ensure long-term water quality
Healthcare environments, particularly hospitals, demand the highest standards of water safety due to the vulnerability of patients and the potential for the spread of infections. We follow the Department of Health’s HTM 04-01 guidelines to ensure that water systems in healthcare settings are properly chlorinated and safe for use.
Key Services for Healthcare Facilities:
Tailored Protocols: We develop custom chlorination plans that cater to the specific needs of critical care units, ensuring patient safety.
Legionella Control: We provide comprehensive Legionella risk assessments, along with testing and monitoring services to prevent the growth of harmful bacteria in healthcare water systems.
How We Can Help:
Expert chlorination services for critical healthcare environments
Ongoing monitoring and compliance with HTM 04-01
Legionella risk assessments and mitigation strategies
Many industries, including manufacturing and agriculture, depend on clean water for their operations. Contaminated water can disrupt processes, damage equipment, and affect product quality. In agricultural settings, ensuring clean water for irrigation is essential to crop health and food safety.
Key Services for Industrial and Agricultural Water Systems:
Customised Chlorination Plans: We design chlorination strategies that meet the specific needs of each industrial or agricultural application, balancing effective disinfection with cost-efficiency.
Environmental Considerations: In agricultural systems, we ensure compliance with the Water Supply (Water Fittings) Regulations 1999 by using environmentally responsible chlorination methods.
How We Can Help:
Chlorination solutions tailored to your industrial or agricultural processes
Environmental stewardship through sustainable water treatment practices
Minimising the Environmental Impact of Chlorination
While chlorination is vital for ensuring water safety, it can have environmental side effects, such as the formation of disinfection by-products (DBPs) and the presence of residual chlorine in discharged water. We are committed to minimising these impacts through environmentally responsible chlorination practices.
How We Minimise Environmental Impact:
We use advanced monitoring systems to apply only the necessary amount of chlorine, reducing excess dosing and limiting the formation of DBPs.
Before treated water is discharged, we neutralise residual chlorine to protect local ecosystems.
Our chlorination processes are designed to be energy-efficient, further reducing our environmental footprint.
