New Mains Chlorination
When new water mains are installed, they must be flushed and disinfected before being connected to the public supply. This is a requirement set by local water authorities to ensure the pipework is free from contamination and suitable for supplying potable water, in line with their specific standards and approval processes.
internal pipework chlorination
Internal pipework chlorination is the process of disinfecting a building’s hot and cold domestic water systems prior to use. This is typically carried out during commissioning to ensure the system is free from contamination and safe to supply potable water to outlets such as taps, drinking points, and showers, in line with UK guidance.
Frequently Asked Questions
Do I need chlorination for new pipework?
Yes — in most cases, new pipework must be disinfected before it can be put into use or connected to the mains water supply. This is typically required by water authorities to ensure the system is safe and compliant before connection approval.
What standard is pipework chlorination carried out to?
Pipework chlorination is carried out in line with current water industry standards and guidance, including BS 8558, HSG 274 and ACoP L8 where applicable. This ensures systems are properly disinfected and certification is accepted for sign-off.
What ppm is used for chlorination?
For most new installations, chlorination is typically carried out at around 50 ppm chlorine concentration. In some cases, alternative methods may be used depending on system requirements and water authority specifications.
How long does pipework chlorination take?
Most pipework chlorination works can be completed within a few hours, including flushing, dosing, contact time and neutralisation. Larger or more complex systems may take longer depending on size and layout.
Do I need a chlorination certificate?
Yes — a chlorination certificate is usually required before a system can be signed off or connected to the mains water supply. We provide certification on completion, accepted by water authorities and clients.
What happens if a water sample fails after chlorination?
If microbiological test results fail, the system may need to be re-flushed and disinfected. We can identify potential causes such as stagnation, poor flushing or dead legs, and carry out any necessary remedial works.
Can you carry out chlorination at short notice?
Yes — we understand that many projects are time-sensitive. We offer fast turnaround and can often attend at short notice depending on availability and location.
Do you carry out mains water chlorination?
Yes — we carry out chlorination of new mains pipework for developers and groundworkers prior to connection. All work is completed in line with required standards, with certification provided for approval.
Do you offer water sampling and testing?
Yes — we provide microbiological water sampling and testing following chlorination to confirm systems are safe. This can include Legionella testing where required.
