Potable Water Chlorination Services in Brentford – Ensuring Safe, Compliant, and Hygienic Water Systems with London Water Treatment

Access to clean and safe drinking water is not just a basic necessity—it's a legal and public health imperative. In Brentford and the wider London area, property owners, facilities managers, and developers are increasingly turning to professional chlorination services to ensure their potable water systems are free of harmful bacteria, meet legal standards, and are fully operational from day one.

At London Water Treatment, we specialise in potable water chlorination services in Brentford, ensuring that your water systems are not only compliant with UK legislation, but also safe, hygienic, and ready for use. With strict adherence to L8 Approved Code of Practice (ACOP) for Legionella prevention and BS8558 standards for water system design, flushing, testing, and disinfection, we provide a gold-standard service you can trust.

Why Chlorinate Potable Water Systems?

Potable water systems, particularly new pipework installations, extensions, and systems left dormant for any length of time, can be vulnerable to bacterial growth—including the potentially deadly Legionella bacteria. Chlorination serves as a critical line of defence, disinfecting your water systems and making them safe for use.

Key Reasons for Potable Water Chlorination:

• Elimination of harmful pathogens including Legionella, E. coli, and Pseudomonas
• Compliance with legal and industry standards (L8 ACOP, BS8558, Water Supply (Water Fittings) Regulations 1999)
• Safe commissioning of new water systems
• Removal of debris, biofilm, and contaminants from pipework
• Ensuring water is safe for human consumption

Our Comprehensive Potable Water Chlorination Process

Here’s how we ensure your potable water system is clean, safe, and fully compliant:

1. Initial Site Survey & Risk Assessment: We begin with a full site survey to understand your system and assess potential risks, particularly for Legionella and other waterborne pathogens. This helps us tailor our disinfection approach to suit the size, complexity, and condition of your water infrastructure.
2. Isolating the System: All necessary outlets are isolated to allow for effective disinfection. Valves are checked, and water is drained where needed to eliminate any stagnant areas that might harbour bacteria.
3. Flushing & Cleaning: The system is thoroughly flushed to remove debris, sediment, or organic matter. This step is vital for ensuring the chlorination process is effective and consistent throughout the system.
4. Dosing with Chlorine Solution: Using a carefully calculated chlorine dose (typically 50ppm – 100ppm for potable systems), we introduce the disinfectant solution and circulate it through the entire system, including pipework, storage tanks, and outlets.
5. Contact Time & Monitoring: We maintain the solution in the system for a defined contact time, typically between 1–12 hours depending on system size and condition. Chlorine residuals are monitored throughout the process to ensure adequate disinfection levels are maintained.
6. Neutralisation & Flushing: After disinfection, the system is flushed with clean water to remove any residual chlorine. We also neutralise any remaining disinfectant where necessary to ensure the system is safe for use.
7. Water Sampling & Microbiological Testing: We take water samples for UKAS-accredited lab testing, checking for bacteria such as Legionella, E. coli, and coliforms. These results confirm the efficacy of the disinfection process.
8. Certification & Reporting: Once tests are passed, we issue you a full chlorination certificate, which includes all compliance data, test results, method statements, and COSHH details—ideal for regulatory inspections or building handovers.

Why L8 ACOP Compliance Matters

The L8 Approved Code of Practice (ACOP) is issued by the UK’s Health and Safety Executive (HSE) and outlines the legal duties for managing and controlling the risk of Legionella in water systems. Failure to comply can lead to severe health risks and legal consequences, especially in environments where people may be more vulnerable, such as hospitals or care homes.

London Water Treatment strictly follows L8 ACOP guidance, ensuring:

• Regular Legionella risk assessments
• Proper system monitoring and maintenance
• Full documentation and record-keeping
• Safe disinfection procedures using approved methods
• Effective staff training and support

Understanding BS8558 – The Gold Standard for Chlorination

BS8558:2015 outlines the best practices for the design, commissioning, flushing, disinfection, and testing of potable water systems. It serves as a companion to the Water Supply (Water Fittings) Regulations 1999 and offers detailed guidance to ensure systems are safe for human consumption.

At London Water Treatment, we adopt BS8558 protocols at every stage of the chlorination process, ensuring:

• Proper calculation of chlorine dosage and contact time
• Accurate sampling and testing
• Full traceability and documentation
• Peace of mind for property owners, developers, and facilities managers

Frequently Asked Questions (FAQs)

Q1: How long does chlorination take?
Ans: Chlorination of potable water systems typically takes between half a day to a full day, depending on system size and complexity. Larger systems or those with significant contamination may require more time.

Q2: Is chlorinated water safe to drink?
Ans: After disinfection, the water system is thoroughly flushed and tested. Only once lab results confirm that the water is safe and meets potable standards, will we certify the system for use.

Q3: Do I need a certificate after chlorination?
Ans: Yes. A chlorination certificate is often required by local authorities, building control officers, or insurers to verify that your system is clean, safe, and compliant with health and safety regulations.

Q4: How often should I chlorinate my system?
Ans: Chlorination is essential when:

• Commissioning a new water system
• Recommissioning after building shutdowns
• After pipework repairs or modifications
• When microbiological testing fails
• At regular intervals as part of planned preventative maintenance
