Need a Chlorination Certificate for a Thames Water Connection?
A new mains connection can be delayed if the required disinfection and water testing have not been completed. We can help with chlorination of the new supply pipe, flushing, sampling and the documentation needed for the connection process.
New pipework can collect dust, debris and standing water during installation. Chlorination treats the system before it is brought into use, while water sampling provides evidence of the result.
If you have a proposed connection date, contact us beforehand. Tell us where the pipework is, what has been installed and when the paperwork is needed.
