Why Is Flushing and Chlorination Important?
Flushing and chlorination are key steps in maintaining water hygiene and preventing waterborne diseases. In the UK, this process isn’t just recommended—it’s often required by law. Here’s why it matters:
- Prevents Contamination: Eliminates harmful microorganisms like Legionella and E. coli.
- Meets Regulatory Standards: Ensures compliance with UK water safety regulations.
- Ensures Water Quality: Maintains consistent, high-quality water supply.
- Protects Public Health: Reduces the risk of waterborne illnesses.
- Extends System Lifespan: Prevents biofilm build-up, protecting pipes and equipment.
The Camelford Water Incident
In 1988, the Camelford water pollution incident in Cornwall highlighted the catastrophic consequences of improper water treatment. This event, where 20 tonnes of aluminium sulphate were accidentally added to the water supply, affected 20,000 people and underscored the critical importance of proper water management and treatment protocols.
When Is Flushing and Chlorination Necessary?
Several scenarios call for this essential process:
- New Installations: Before connecting new pipework to mains supply.
- System Modifications: After repairs or extensions to existing systems.
- After Periods of Inactivity: For seasonal businesses or holiday homes.
- Routine Maintenance: Often conducted annually as part of water safety plans.
- Contamination Incidents: Immediate action required if testing reveals harmful bacteria.
Risk assessments play a crucial role in determining the frequency of chlorination. Factors such as system complexity, usage patterns, and historical data inform these assessments.
The Flushing and Chlorination Process: A Step-by-Step Guide
- Initial Assessment: Our experts evaluate your water system, identifying potential risk areas and determining the most effective approach.
- Flushing: We run clean water through the system to remove debris, dirt, and installation residues. This crucial step ensures the effectiveness of subsequent chlorination.
- Chlorine Application: We introduce a chlorine solution at a concentration of at least 50 mg/l. The chlorine reacts with water to form hypochlorous acid, a powerful disinfectant.
- Contact Period: The chlorine solution remains in the system for about an hour. During this time, the disinfectant eliminates harmful microorganisms by disrupting their cellular processes.
- Neutralisation and Disposal: We neutralise the chlorine using sodium thiosulphate and flush the system again with clean water. This step ensures the water is safe for use and environmentally friendly disposal.
- Testing and Certification: We conduct comprehensive sampling and provide documentation certifying the process. Water samples are tested for residual chlorine levels and absence of harmful bacteria.
What are the signs of ineffective chlorination?
Signs may include persistent bacterial growth in water samples, recurring biofilm formation, or failure to meet regulatory standards in water quality tests.
UK-Specific Considerations for Flushing and Chlorination
In the UK, flushing and chlorination must comply with specific standards:
- BS 8558:2015 and PD 855468 guidelines for design, installation, and maintenance of water systems.
- Water Supply (Water Fittings) Regulations 1999, enforcing standards for water fittings and preventing contamination.
- UKAS-accredited laboratory certification to ensure reliable testing results.
- Local water authority guidelines, which may vary by region. For instance, Thames Water has specific requirements for new connections.
- Health and Safety Executive (HSE) guidance on managing Legionella risks.
The Drinking Water Inspectorate (DWI) plays a crucial role in setting and enforcing drinking water quality standards in England and Wales, influencing chlorination practices nationwide.

FAQs - Flushing and Chlorination
How often should water systems undergo flushing and chlorination?
The frequency depends on various factors, including system usage and risk assessment results. Generally, it’s recommended annually for most systems. High-risk facilities may require more frequent treatment.
Is flushing and chlorination safe for all types of pipework?
While suitable for most pipework, some materials may require special consideration. Our experts will assess your system and recommend the most appropriate treatment.
How long does the flushing and chlorination process take?
The duration varies depending on system size and complexity. Typically, it takes several hours to a full day. We’ll provide a detailed timeline during our initial assessment.
Can I use my water system during the flushing and chlorination process?
No, the system must be isolated during treatment. We’ll work with you to minimise disruption and schedule the process at a convenient time.
How do I know if my water system needs flushing and chlorination?
Signs include discoloured water, unusual odours, recent plumbing work, or positive tests for waterborne bacteria. If in doubt, contact us for a professional assessment.
What documentation will I receive after the flushing and chlorination process?
We provide a comprehensive chlorination certificate, detailing the process and results. This document is often required by water authorities and building inspectors.
How does chlorination affect water taste and smell?
Properly executed chlorination should not significantly affect taste or smell. If you notice strong chlorine odours, it may indicate over-chlorination, and you should contact a professional for assessment.
How has technology improved the chlorination process?
Recent advancements include automated dosing systems, real-time monitoring devices, and more efficient chlorine compounds. These innovations enhance accuracy and effectiveness while reducing environmental impact.
